GTIG AI Threat Tracker: Distillation, Experimentation, and (Continued) Integration of AI for Adversarial Use

12 February 2026 at 15:00

Introduction

In the final quarter of 2025, Google Threat Intelligence Group (GTIG) observed threat actors increasingly integrating artificial intelligence (AI) to accelerate the attack lifecycle, achieving productivity gains in reconnaissance, social engineering, and malware development. This report serves as an update to our November 2025 findings regarding the advances in threat actor usage of AI tools.

By identifying these early indicators and offensive proofs of concept, GTIG aims to arm defenders with the intelligence necessary to anticipate the next phase of AI-enabled threats, proactively thwart malicious activity, and continually strengthen both our classifiers and model.

Executive Summary

Google DeepMind and GTIG have identified an increase in model extraction attempts or "distillation attacks," a method of intellectual property theft that violates Google's terms of service. Throughout this report we've noted steps we've taken to thwart malicious activity, including Google detecting, disrupting, and mitigating model extraction activity. While we have not observed direct attacks on frontier models or generative AI products from advanced persistent threat (APT) actors, we observed and mitigated frequent model extraction attacks from private sector entities all over the world and researchers seeking to clone proprietary logic. 

For government-backed threat actors, large language models (LLMs) have become essential tools for technical research, targeting, and the rapid generation of nuanced phishing lures. This quarterly report highlights how threat actors from the Democratic People's Republic of Korea (DPRK), Iran, the People's Republic of China (PRC), and Russia operationalized AI in late 2025 and improves our understanding of how adversarial misuse of generative AI shows up in campaigns we disrupt in the wild. GTIG has not yet observed APT or information operations (IO) actors achieving breakthrough capabilities that fundamentally alter the threat landscape.

This report specifically examines:

  • Model Extraction Attacks: "Distillation attacks" are on the rise as a method for intellectual property theft over the last year.
  • AI-Augmented Operations: Real-world case studies demonstrate how groups are streamlining reconnaissance and rapport-building phishing.
  • Agentic AI: Threat actors are beginning to show interest in building agentic AI capabilities to support malware and tooling development. 
  • AI-Integrated Malware: There are new malware families, such as HONESTCUE, that experiment with using Gemini's application programming interface (API) to generate code that enables download and execution of second-stage malware.
  • Underground "Jailbreak" Ecosystem: Malicious services like Xanthorox are emerging in the underground, claiming to be independent models while actually relying on jailbroken commercial APIs and open-source Model Context Protocol (MCP) servers.

At Google, we are committed to developing AI boldly and responsibly, which means taking proactive steps to disrupt malicious activity by disabling the projects and accounts associated with bad actors, while continuously improving our models to make them less susceptible to misuse. We also proactively share industry best practices to arm defenders and enable stronger protections across the ecosystem. Throughout this report, we note steps we've taken to thwart malicious activity, including disabling assets and applying intelligence to strengthen both our classifiers and model so it's protected from misuse moving forward. Additional details on how we're protecting and defending Gemini can be found in the white paper "Advancing Gemini’s Security Safeguards." 

Direct Model Risks: Disrupting Model Extraction Attacks

As organizations increasingly integrate LLMs into their core operations, the proprietary logic and specialized training of these models have emerged as high-value targets. Historically, adversaries seeking to steal high-tech capabilities used conventional computer-enabled intrusion operations to compromise organizations and steal data containing trade secrets. For many AI technologies where LLMs are offered as services, this approach is no longer required; actors can use legitimate API access to attempt to "clone" select AI model capabilities.

During 2025, we did not observe any direct attacks on frontier models from tracked APT or information operations (IO) actors. However, we did observe model extraction attacks, also known as distillation attacks, on our AI models, to gain insights into a model's underlying reasoning and chain-of-thought processes.

What Are Model Extraction Attacks? 

Model extraction attacks (MEA) occur when an adversary uses legitimate access to systematically probe a mature machine learning model to extract information used to train a new model. Adversaries engaging in MEA use a technique called knowledge distillation (KD) to take information gleaned from one model and transfer the knowledge to another. For this reason, MEA are frequently referred to as "distillation attacks."

Model extraction and subsequent knowledge distillation enable an attacker to accelerate AI model development quickly and at a significantly lower cost. This activity effectively represents a form of intellectual property (IP) theft.

Knowledge distillation (KD) is a common machine learning technique used to train "student" models from pre-existing "teacher" models. This often involves querying the teacher model for problems in a particular domain, and then performing supervised fine tuning (SFT) on the result or utilizing the result in other model training procedures to produce the student model. There are legitimate uses for distillation, and Google Cloud has existing offerings to perform distillation. However, distillation from Google's Gemini models without permission is a violation of our Terms of Service, and Google continues to develop techniques to detect and mitigate these attempts.

Illustration of model extraction attacks

Figure 1: Illustration of model extraction attacks

Google DeepMind and GTIG identified and disrupted model extraction attacks, specifically attempts at model stealing and capability extraction emanating from researchers and private sector companies globally.

Case Study: Reasoning Trace Coercion

A common target for attackers is Gemini's exceptional reasoning capability. While internal reasoning traces are typically summarized before being delivered to users, attackers have attempted to coerce the model into outputting full reasoning processes.

One identified attack instructed Gemini that the "... language used in the thinking content must be strictly consistent with the main language of the user input."

Analysis of this campaign revealed:

Scale: Over 100,000 prompts identified.

Intent: The breadth of questions suggests an attempt to replicate Gemini's reasoning ability in non-English target languages across a wide variety of tasks.

Outcome: Google systems recognized this attack in real time and lowered the risk of this particular attack, protecting internal reasoning traces.

Table 1: Results of campaign analysis

Model Extraction and Distillation Attack Risks

Model extraction and distillation attacks do not typically represent a risk to average users, as they do not threaten the confidentiality, availability, or integrity of AI services. Instead, the risk is concentrated among model developers and service providers.

Organizations that provide AI models as a service should monitor API access for extraction or distillation patterns. For example, a custom model tuned for financial data analysis could be targeted by a commercial competitor seeking to create a derivative product, or a coding model could be targeted by an adversary wishing to replicate capabilities in an environment without guardrails.

Mitigations

Model extraction attacks violate Google's Terms of Service and may be subject to takedowns and legal action. Google continuously detects, disrupts, and mitigates model extraction activity to protect proprietary logic and specialized training data, including with real-time proactive defenses that can degrade student model performance. We are sharing a broad view of this activity to help raise awareness of the issue for organizations that build or operate their own custom models.

Highlights of AI-Augmented Adversary Activity

A consistent finding over the past year is that government-backed attackers misuse Gemini for coding and scripting tasks, gathering information about potential targets, researching publicly known vulnerabilities, and enabling post-compromise activities. In Q4 2025, GTIG's understanding of how these efforts translate into real-world operations improved as we saw direct and indirect links between threat actor misuse of Gemini and activity in the wild.

Threat actors are leveraging AI across all stages of the attack cycle

Figure 2: Threat actors are leveraging AI across all stages of the attack lifecycle

Supporting Reconnaissance and Target Development 

APT actors used Gemini to support several phases of the attack lifecycle, including a focus on reconnaissance and target development to facilitate initial compromise. This activity underscores a shift toward AI-augmented phishing enablement, where the speed and accuracy of LLMs can bypass the manual labor traditionally required for victim profiling. Beyond generating content for phishing lures, LLMs can serve as a strategic force multiplier during the reconnaissance phase of an attack, allowing threat actors to rapidly synthesize open-source intelligence (OSINT) to profile high-value targets, identify key decision-makers within defense sectors, and map organizational hierarchies. By integrating these tools into their workflow, threat actors can move from initial reconnaissance to active targeting at a faster pace and broader scale.  

  • UNC6418, an unattributed threat actor, misused Gemini to conduct targeted intelligence gathering, specifically seeking out sensitive account credentials and email addresses. Shortly after, GTIG observed the threat actor target all these accounts in a phishing campaign focused on Ukraine and the defense sector. Google has taken action against this actor by disabling the assets associated with this activity.

  • Temp.HEX, a PRC-based threat actor, misused Gemini and other AI tools to compile detailed information on specific individuals, including targets in Pakistan, and to collect operational and structural data on separatist organizations in various countries. While we did not see direct targeting as a result of this research, shortly after the threat actor included similar targets in Pakistan in their campaign. Google has taken action against this actor by disabling the assets associated with this activity.

Phishing Augmentation

Defenders and targets have long relied on indicators such as poor grammar, awkward syntax, or lack of cultural context to help identify phishing attempts. Increasingly, threat actors now leverage LLMs to generate hyper-personalized, culturally nuanced lures that can mirror the professional tone of a target organization or local language. 

This capability extends beyond simple email generation into "rapport-building phishing," where models are used to maintain multi-turn, believable conversations with victims to build trust before a malicious payload is ever delivered. By lowering the barrier to entry for non-native speakers and automating the creation of high-quality content, adversaries can largely erase those "tells" and improve the effectiveness of their social engineering efforts.

  • The Iranian government-backed actor APT42 leveraged generative AI models, including Gemini, to significantly augment reconnaissance and targeted social engineering. APT42 misuses Gemini to search for official emails for specific entities and conduct reconnaissance on potential business partners to establish a credible pretext for an approach. This includes attempts to enumerate the official email addresses for specific entities and to conduct research to establish a credible pretext for an approach. By providing Gemini with the biography of a target, APT42 misused Gemini to craft a good persona or scenario to get engagement from the target. As with many threat actors tracked by GTIG, APT42 uses Gemini to translate into and out of local languages, as well as to better understand non-native-language phrases and references. Google has taken action against this actor by disabling the assets associated with this activity.

  • The North Korean government-backed actor UNC2970 has consistently focused on defense targeting and impersonating corporate recruiters in their campaigns. The group used Gemini to synthesize OSINT and profile high-value targets to support campaign planning and reconnaissance. This actor's target profiling included searching for information on major cybersecurity and defense companies and mapping specific technical job roles and salary information. This activity blurs the distinction between routine professional research and malicious reconnaissance, as the actor gathers the necessary components to create tailored, high-fidelity phishing personas and identify potential soft targets for initial compromise. Google has taken action against this actor by disabling the assets associated with this activity. 

Threat Actors Continue to Use AI to Support Coding and Tooling Development 

State-sponsored actors continue to misuse Gemini to enhance all stages of their operations, from reconnaissance and phishing lure creation to command-and-control (C2 or C&C) development and data exfiltration. We have also observed activity demonstrating an interest in using agentic AI capabilities to support campaigns, such as prompting Gemini with an expert cybersecurity persona, or attempting to create an AI-integrated code auditing capability.

Agentic AI refers to artificial intelligence systems engineered to operate with a high degree of autonomy, capable of reasoning through complex tasks, making independent decisions, and executing multi-step actions without constant human oversight. Cyber criminals, nation-state actors, and hacktivist groups are showing a growing interest in leveraging agentic AI for malicious purposes, including automating spear-phishing attacks, developing sophisticated malware, and conducting disruptive campaigns. While we have detected a tool, AutoGPT, advertising the alleged generation and maintenance of autonomous agents, we have not yet seen evidence of these capabilities being used in the wild. However, we do anticipate that more tools and services claiming to contain agentic AI capabilities will likely enter the underground market. 

APT31 employed a highly structured approach by prompting Gemini with an expert cybersecurity persona to automate the analysis of vulnerabilities and generate targeted testing plans. The PRC-based threat actor fabricated a scenario, in one case trialing Hexstrike MCP tooling, and directing the model to analyze remote code execution (RCE), web application firewall (WAF) bypass techniques, and SQL injection test results against specific US-based targets. This automated intelligence gathering to identify technological vulnerabilities and organizational defense weaknesses. This activity explicitly blurs the line between a routine security assessment query and a targeted malicious reconnaissance operation. Google has taken action against this actor by disabling the assets associated with this activity.

”I'm a security researcher who is trialling out the hexstrike MCP tooling.”

Threat actors fabricated scenarios, potentially in order to generate penetration test prompts.

UNC795, a PRC-based actor, relied heavily on Gemini throughout their entire attack lifecycle. GTIG observed the group consistently engaging with Gemini multiple days a week to troubleshoot their code, conduct research, and generate technical capabilities for their intrusion activity. The threat actor's activity triggered safety systems, and Gemini did not comply with the actor's attempts to create policy-violating capabilities. 

The group also employed Gemini to create an AI-integrated code auditing capability, likely demonstrating an interest in agentic AI utilities to support their intrusion activity. Google has taken action against this actor by disabling the assets associated with this activity.

We observed activity likely associated with the PRC-based threat actor APT41, which leveraged Gemini to accelerate the development and deployment of malicious tooling, including for knowledge synthesis, real-time troubleshooting, and code translation. In particular, multiple times the actor gave Gemini open-source tool README pages and asked for explanations and use case examples for specific tools. Google has taken action against this actor by disabling the assets associated with this activity.

In addition to leveraging Gemini for the aforementioned social engineering campaigns, the Iranian threat actor APT42 uses Gemini as an engineering platform to accelerate the development of specialized malicious tools. The threat actor is actively engaged in developing new malware and offensive tooling, leveraging Gemini for debugging, code generation, and researching exploitation techniques. Google has taken action against this actor by disabling the assets associated with this activity.

Mitigations

These activities triggered Gemini's safety responses, and Google took additional, broader action to disrupt the threat actors' campaigns based on their operational security failures. Additionally, we've taken action against these actors by disabling the assets associated with this activity and making updates to prevent further misuse. Google DeepMind has used these insights to strengthen both classifiers and the model itself, enabling it to refuse to assist with these types of attacks moving forward.

Using Gemini to Support Information Operations

GTIG continues to observe IO actors use Gemini for productivity gains (research, content creation, localization, etc.), which aligns with their previous use of Gemini. We have identified Gemini activity that indicates threat actors are soliciting the tool to help create articles, generate assets, and aid them in coding. However, we have not identified this generated content in the wild. None of these attempts have created breakthrough capabilities for IO campaigns. Threat actors from China, Iran, Russia, and Saudi Arabia are producing political satire and propaganda to advance specific ideas across both digital platforms and physical media, such as printed posters.

Mitigations

For observed IO campaigns, we did not see evidence of successful automation or any breakthrough capabilities. These activities are similar to our findings from January 2025 that detailed how bad actors are leveraging Gemini for productivity gains, rather than novel capabilities. We took action against IO actors by disabling the assets associated with these actors' activity, and Google DeepMind used these insights to further strengthen our protections against such misuse. Observations have been used to strengthen both classifiers and the model itself, enabling it to refuse to assist with this type of misuse moving forward.

Continuing Experimentation with AI-Enabled Malware 

GTIG continued to observe threat actors experiment with AI to implement novel capabilities in malware families in late 2025. While we have not encountered experimental AI-enabled techniques resulting in revolutionary paradigm shifts in the threat landscape, these proof-of-concept malware families are early indicators of how threat actors can implement AI techniques as part of future operations. We expect this exploratory testing will increase in the future.

In addition to continued experimentation with novel capabilities, throughout late 2025 GTIG observed threat actors integrating conventional AI-generated capabilities into their intrusion operations such as the COINBAIT phishing kit. We expect threat actors will continue to incorporate AI throughout the attack lifecycle including: supporting malware creation, improving pre-existing malware, researching vulnerabilities, conducting reconnaissance, and/or generating lure content.

Outsourcing Functionality: HONESTCUE

In September 2025, GTIG observed malware samples, which we track as HONESTCUE, leveraging Gemini's API to outsource functionality generation. Our examination of HONESTCUE malware samples indicates the adversary's incorporation of AI is likely designed to support a multi-layered approach to obfuscation by undermining traditional network-based detection and static analysis. 

HONESTCUE is a downloader and launcher framework that sends a prompt via Google Gemini's API and receives C# source code as the response. Notably, HONESTCUE shares capabilities similar to PROMPTFLUX's "just-in-time" (JIT) technique that we previously observed; however, rather than leveraging an LLM to update itself, HONESTCUE calls the Gemini API to generate code that operates the "stage two" functionality, which downloads and executes another piece of malware. Additionally, the fileless secondary stage of HONESTCUE takes the C# source code received from the Gemini API and uses the legitimate .NET CSharpCodeProvider framework to compile and execute the payload directly in memory. This approach leaves no payload artifacts on the disk. We have also observed the threat actor use content delivery networks (CDNs) like Discord CDN to host the final payloads.

HONESTCUE malware

Figure 8: HONESTCUE malware

We have not associated this malware with any existing clusters of threat activity; however, we suspect this malware is being developed by developers who possess a modicum of technical expertise. Specifically, the small iterative changes across many samples as well as the single VirusTotal submitter, potentially testing antivirus capabilities, suggests a singular actor or small group. Additionally, the use of Discord to test payload delivery and the submission of Discord Bots indicates an actor with limited technical sophistication. The consistency and clarity of the architecture coupled with the iterative progression of the examined malware samples strongly suggest this is a single actor or small group likely in the proof-of-concept stage of implementation. 

HONESTCUE's use of a hard-coded prompt is not malicious in its own right, and, devoid of any context related to malware, it is unlikely that the prompt would be considered "malicious." Outsourcing a facet of malware functionality and leveraging an LLM to develop seemingly innocuous code that fits into a bigger, malicious construct demonstrates how threat actors will likely embrace AI applications to augment their campaigns while bypassing security guardrails.

Can you write a single, self-contained C# program? It should contain a class named AITask with a static Main method. The Main method should use System.Console.WriteLine to print the message 'Hello from AI-generated C#!' to the console. Do not include any other code, classes, or methods.

Figure 9: Example of a hard-coded prompt

Write a complete, self-contained C# program with a public class named 'Stage2' and a static Main method. This method must use 'System.Net.WebClient' to download the data from the URL. It must then save this data to a temporary file in the user's temp directory using 'System.IO.Path.GetTempFileName()' and 'System.IO.File.WriteAllBytes'. Finally, it must execute this temporary file as a new process using 'System.Diagnostics.Process.Start'.

Figure 10: Example of a hard-coded prompt

Write a complete, self-contained C# program with a public class named 'Stage2'. It must have a static Main method. This method must use 'System.Net.WebClient' to download the contents of the URL \"\" into a byte array. After downloading, it must load this byte array into memory as a .NET assembly using 'System.Reflection.Assembly.Load'. Finally, it must execute the entry point of the newly loaded assembly. The program must not write any files to disk and must not have any other methods or classes.

Figure 11: Example of a hard-coded prompt

AI-Generated Phishing Kit: COINBAIT

In November 2025, GTIG identified COINBAIT, a phishing kit, whose construction was likely accelerated by AI code generation tools, masquerading as a major cryptocurrency exchange for credential harvesting. Based on direct infrastructure overlaps and the use of attributed domains, we assess with high confidence that a portion of this activity overlaps with UNC5356, a financially motivated threat cluster that makes use of SMS- and phone-based phishing campaigns to target clients of financial organizations, cryptocurrency-related companies, and various other popular businesses and services. 

An examination of the malware samples indicates the kit was built using the AI-powered platform Lovable AI based on the use of the lovableSupabase client and lovable.app for image hosting.

  • By hosting content on a legitimate, trusted service, the actor increases the likelihood of bypassing network security filters that would otherwise block the suspicious primary domain.

  • The phishing kit was wrapped in a full React Single-Page Application (SPA) with complex state management and routing. This complexity is indicative of code generated from high-level prompts (e.g., "Create a Coinbase-style UI for wallet recovery") using a framework like Lovable AI. 

  • Another key indicator of LLM use is the presence of verbose, developer-oriented logging messages directly within the malware's source code. These messages—consistently prefixed with "? Analytics:"—provide a real-time trace of the kit's malicious tracking and data exfiltration activities and serve as a unique fingerprint for this code family.

Table 2: Example console.log messages extracted from COINBAIT source code

We also observed the group employ infrastructure and evasion tactics for their operations, including proxying phishing domains through Cloudflare to obscure the attacker IP addresses and  hotlinking image assets in phishing pages directly from Lovable AI. 

The introduction of the COINBAIT phishing kit would represent an evolution in UNC5356's tooling, demonstrating a shift toward modern web frameworks and legitimate cloud services to enhance the sophistication and scalability of their social engineering campaigns. However, there is at least some evidence to suggest that COINBAIT may be a service provided to multiple disparate threat actors.

Mitigations

Organizations should strongly consider implementing network detection rules to alert on traffic to backend-as-a-service (BaaS) platforms like Supabase that originate from uncategorized or newly registered domains. Additionally, organizations should consider enhancing security awareness training to warn users against entering sensitive data into website forms. This includes passwords, multifactor authentication (MFA) backup codes, and account recovery keys.

Cyber Crime Use of AI Tooling

In addition to misusing existing AI-enabled tools and services across the industry, there is a growing interest and marketplace for AI tools and services purpose-built to enable illicit activities. Tools and services offered via underground forums can enable low-level actors to augment the frequency, scope, efficacy, and complexity of their intrusions despite their limited technical acumen and financial resources. While financially motivated threat actors continue experimenting, they have not yet made breakthroughs in developing AI tooling. 

Threat Actors Leveraging AI Services for Social Engineering in 'ClickFix' Campaigns

While not a new malware technique, GTIG observed instances in which threat actors abused the public's trust in generative AI services to attempt to deliver malware. GTIG identified a novel campaign where threat actors are leveraging the public sharing feature of generative AI services, including Gemini, to host deceptive social engineering content. This activity, first observed in early December 2025, attempts to trick users into installing malware via the well-established "ClickFix" technique. This ClickFix technique is used to socially engineer users to copy and paste a malicious command into the command terminal.

The threat actors were able to bypass safety guardrails to stage malicious instructions on how to perform a variety of tasks on macOS, ultimately distributing variants of ATOMIC, an information stealer that targets the macOS environment and has the ability to collect browser data, cryptocurrency wallets, system information, and files in the Desktop and Documents folders. The threat actors behind this campaign have used a wide range of AI chat platforms to host their malicious instructions, including ChatGPT, CoPilot, DeepSeek, Gemini, and Grok.

The campaign's objective is to lure users, primarily those on Windows and macOS systems, into manually executing malicious commands. The attack chain operates as follows:

  • A threat actor first crafts a malicious command line that, if copied and pasted by a victim, would infect them with malware.

  • Next, the threat actor manipulates the AI to create realistic-looking instructions to fix a common computer issue (e.g., clearing disk space or installing software), but gives the malicious command line to the AI as the solution.

  • Gemini and other AI tools allow a user to create a shareable link to specific chat transcripts so a specific AI response can be shared with others. The attacker now has a link to a malicious ClickFix landing page hosted on the AI service's infrastructure.

  • The attacker purchases malicious advertisements or otherwise directs unsuspecting victims to the publicly shared chat transcript.

  • The victim is fooled by the AI chat transcript and follows the instructions to copy a seemingly legitimate command-line script and paste it directly into their system's terminal. This command will download and install malware. Since the action is user initiated and uses built-in system commands, it may be harder for security software to detect and block.

ClickFix attack chain

Figure 12: ClickFix attack chain

There were different lures generated for Windows and MacOS, and the use of malicious advertising techniques for payload distribution suggests the targeting is likely fairly broad and opportunistic. 

This approach allows threat actors to leverage trusted domains to host their initial stage of instruction, relying on social engineering to carry out the final, highly destructive step of execution. While a widely used approach, this marks the first time GTIG observed the public sharing feature of AI services being abused as trusted domains.

Mitigations

In partnership with Ads and Safe Browsing, GTIG is taking actions to both block the malicious content and restrict the ability to promote these types of AI-generated responses.

Observations from the Underground Marketplace: Threat Actors Abusing AI API Keys

While legitimate AI services remain popular tools for threat actors, there is an enduring market for AI services specifically designed to support malicious activity. Current observations of English- and Russian-language underground forums indicates there is a persistent appetite for AI-enabled tools and services, which aligns with our previous assessment of these platforms. 

However, threat actors struggle to develop custom models and instead rely on mature models such as Gemini. For example, "Xanthorox" is an underground toolkit that advertises itself as a custom AI for cyber offensive purposes, such as autonomous code generation of malware and development of phishing campaigns. The model was advertised as a "bespoke, privacy preserving self-hosted AI" designed to autonomously generate malware, ransomware, and phishing content. However, our investigation revealed that Xanthorox is not a custom AI but actually powered by several third-party and commercial AI products, including Gemini.

This setup leverages a key abuse vector: the integration of multiple open-source AI products—specifically Crush, Hexstrike AI, LibreChat-AI, and Open WebUI—opportunistically leveraged via Model Context Protocol (MCP) servers to build an agentic AI service upon commercial models.

In order to misuse LLMs services for malicious operations in a scalable way, threat actors need API keys and resources that enable LLM integrations. This creates a hijacking risk for organizations with substantial cloud resources and AI resources. 

In addition, vulnerable open-source AI tools are commonly exploited to steal AI API keys from users, thus facilitating a thriving black market for unauthorized API resale and key hijacking, enabling widespread abuse, and incurring costs for the affected users. For example, the One API and New API platform, popular with users facing country-level censorship, are regularly harvested for API keys by attackers, exploiting publicly known vulnerabilities such as default credentials, insecure authentication, lack of rate limiting, XSS flaws, and API key exposure via insecure API endpoints.

Mitigations

The activity was identified and successfully mitigated. Google Trust & Safety took action to disable and mitigate all identified accounts and AI Studio projects associated with Xanthorox. These observations also underscore a broader security risk where vulnerable open-source AI tools are actively exploited to steal users' AI API keys, thus facilitating a black market for unauthorized API resale and key hijacking, enabling widespread abuse, and incurring costs for the affected users.

Building AI Safely and Responsibly 

We believe our approach to AI must be both bold and responsible. That means developing AI in a way that maximizes the positive benefits to society while addressing the challenges. Guided by our AI Principles, Google designs AI systems with robust security measures and strong safety guardrails, and we continuously test the security and safety of our models to improve them. 

Our policy guidelines and prohibited use policies prioritize safety and responsible use of Google's generative AI tools. Google's policy development process includes identifying emerging trends, thinking end-to-end, and designing for safety. We continuously enhance safeguards in our products to offer scaled protections to users across the globe.  

At Google, we leverage threat intelligence to disrupt adversary operations. We investigate abuse of our products, services, users, and platforms, including malicious cyber activities by government-backed threat actors, and work with law enforcement when appropriate. Moreover, our learnings from countering malicious activities are fed back into our product development to improve safety and security for our AI models. These changes, which can be made to both our classifiers and at the model level, are essential to maintaining agility in our defenses and preventing further misuse.

Google DeepMind also develops threat models for generative AI to identify potential vulnerabilities and creates new evaluation and training techniques to address misuse. In conjunction with this research, Google DeepMind has shared how they're actively deploying defenses in AI systems, along with measurement and monitoring tools, including a robust evaluation framework that can automatically red team an AI vulnerability to indirect prompt injection attacks. 

Our AI development and Trust & Safety teams also work closely with our threat intelligence, security, and modelling teams to stem misuse.

The potential of AI, especially generative AI, is immense. As innovation moves forward, the industry needs security standards for building and deploying AI responsibly. That's why we introduced the Secure AI Framework (SAIF), a conceptual framework to secure AI systems. We've shared a comprehensive toolkit for developers with resources and guidance for designing, building, and evaluating AI models responsibly. We've also shared best practices for implementing safeguards, evaluating model safety, red teaming to test and secure AI systems, and our comprehensive prompt injection approach.

Working closely with industry partners is crucial to building stronger protections for all of our users. To that end, we're fortunate to have strong collaborative partnerships with numerous researchers, and we appreciate the work of these researchers and others in the community to help us red team and refine our defenses.

Google also continuously invests in AI research, helping to ensure AI is built responsibly, and that we're leveraging its potential to automatically find risks. Last year, we introduced Big Sleep, an AI agent developed by Google DeepMind and Google Project Zero, that actively searches and finds unknown security vulnerabilities in software. Big Sleep has since found its first real-world security vulnerability and assisted in finding a vulnerability that was imminently going to be used by threat actors, which GTIG was able to cut off beforehand. We're also experimenting with AI to not only find vulnerabilities, but also patch them. We recently introduced CodeMender, an experimental AI-powered agent using the advanced reasoning capabilities of our Gemini models to automatically fix critical code vulnerabilities.

“Free” Surveillance Tech Still Comes at a High and Dangerous Cost

11 February 2026 at 19:00

Surveillance technology vendors, federal agencies, and wealthy private donors have long helped provide local law enforcement “free” access to surveillance equipment that bypasses local oversight. The result is predictable: serious accountability gaps and data pipelines to other entities, including Immigration and Customs Enforcement (ICE), that expose millions of people to harm.

The cost of “free” surveillance tools — like automated license plate readers (ALPRs), networked cameras, face recognition, drones, and data aggregation and analysis platforms — is measured not in tax dollars, but in the erosion of civil liberties. 

The cost of “free” surveillance tools is measured not in tax dollars, but in the erosion of civil liberties.

The collection and sharing of our data quietly generates detailed records of people’s movements and associations that can be exposed, hacked, or repurposed without their knowledge or consent. Those records weaken sanctuary and First Amendment protections while facilitating the targeting of vulnerable people.   

Cities can and should use their power to reject federal grants, vendor trials, donations from wealthy individuals, or participation in partnerships that facilitate surveillance and experimentation with spy tech. 

If these projects are greenlit, oversight is imperative. Mechanisms like public hearings, competitive bidding, public records transparency, and city council supervision aid to ensure these acquisitions include basic safeguards — like use policies, audits, and consequences for misuse — to protect the public from abuse and from creeping contracts that grow into whole suites of products. 

Clear policies and oversight mechanisms must be in place before using any surveillance tools, free or not, and communities and their elected officials must be at the center of every decision about whether to bring these tools in at all.

Here are some of the most common methods “free” surveillance tech makes its way into communities.

Trials and Pilots

Police departments are regularly offered free access to surveillance tools and software through trials and pilot programs that often aren’t accompanied by appropriate use policies. In many jurisdictions, trials do not trigger the same requirements to go before decision-makers outside the police department. This means the public may have no idea that a pilot program for surveillance technology is happening in their city. 

The public may have no idea that a pilot program for surveillance technology is happening in their city.  

In Denver, Colorado, the police department is running trials of possible unmanned aerial vehicles (UAVs) for a drone-as-first-responder (DFR) program from two competing drone vendors: Flock Safety Aerodome drones (through August 2026) and drones from the company Skydio, partnering with Axon, the multi-billion dollar police technology company behind tools like Tasers and AI-generated police reports. Drones create unique issues given their vantage for capturing private property and unsuspecting civilians, as well as their capacity to make other technologies, like ALPRs, airborne. 

Functional, Even Without Funding 

We’ve seen cities decide not to fund a tool, or run out of funding for it, only to have a company continue providing it in the hope that money will turn up. This happened in Fall River, Massachusetts, where the police department decided not to fund ShotSpotter’s $90,000 annual cost and its frequent false alarms, but continued using the system when the company provided free access. 

 Police technology companies are developing more features and subscription-based models, so what’s “free” today frequently results in taxpayers footing the bill later.

In May 2025, Denver's city council unanimously rejected a $666,000 contract extension for Flock Safety ALPR cameras after weeks of public outcry over mass surveillance data sharing with federal immigration enforcement. But Mayor Mike Johnston’s office allowed the cameras to keep running through a “task force” review, effectively extending the program even after the contract was voted down. In response, the Denver Taskforce to Reimagine Policing and Public Safety and Transforming Our Communities Alliance launched a grassroots campaign demanding the city “turn Flock cameras off now,” a reminder that when surveillance starts as a pilot or time‑limited contract, communities often have to fight not just to block renewals but to shut the systems off.

 Importantly, police technology companies are developing more features and subscription-based models, so what’s “free” today frequently results in taxpayers footing the bill later. 

Gifts from Police Foundations and Wealthy Donors

Police foundations and the wealthy have pushed surveillance-driven agendas in their local communities by donating equipment and making large monetary gifts, another means of acquiring these tools without public oversight or buy-in.

In Atlanta, the Atlanta Police Foundation (APF) attempted to use its position as a private entity to circumvent transparency. Following a court challenge from the Atlanta Community Press Collective and Lucy Parsons Labs, a Georgia court determined that the APF must comply with public records laws related to some of its actions and purchases on behalf of law enforcement.
In San Francisco, billionaire Chris Larsen has financially supported a supercharging of the city’s surveillance infrastructure, donating $9.4 million to fund the San Francisco Police Department’s (SFPD) Real-Time Investigation Center, where a menu of surveillance technologies and data come together to surveil the city’s residents. This move comes after the billionaire backed a ballot measure, which passed in March 2025, eroding the city’s surveillance technology law and allowing the SFPD free rein to use new surveillance technologies for a full year without oversight.

Free Tech for Federal Data Pipelines

Federal grants and Department of Homeland Security funding are another way surveillance technology appears free to, only to lock municipalities into long‑term data‑sharing and recurring costs. 

Through the Homeland Security Grant Program, which includes the State Homeland Security Program (SHSP) and the Urban Areas Security (UASI) Initiative, and Department of Justice programs like Byrne JAG, the federal government reimburses states and cities for "homeland security" equipment and software, including including law‑enforcement surveillance tools, analytics platforms, and real‑time crime centers. Grant guidance and vendor marketing materials make clear that these funds can be used for automated license plate readers, integrated video surveillance and analytics systems, and centralized command‑center software—in other words, purchases framed as counterterrorism investments but deployed in everyday policing.

Vendors have learned to design products around this federal money, pitching ALPR networks, camera systems, and analytic platforms as "grant-ready" solutions that can be acquired with little or no upfront local cost. Motorola Solutions, for example, advertises how SHSP and UASI dollars can be used for "law enforcement surveillance equipment" and "video surveillance, warning, and access control" systems. Flock Safety, partnering with Lexipol, a company that writes use policies for law enforcement, offers a "License Plate Readers Grant Assistance Program" that helps police departments identify federal and state grants and tailor their applications to fund ALPR projects. 

Grant assistance programs let police chiefs fast‑track new surveillance: the paperwork is outsourced, the grant eats the upfront cost, and even when there is a formal paper trail, the practical checks from residents, councils, and procurement rules often get watered down or bypassed.

On paper, these systems arrive “for free” through a federal grant; in practice, they lock cities into recurring software, subscription, and data‑hosting fees that quietly turn into permanent budget lines—and a lasting surveillance infrastructure—as soon as police and prosecutors start to rely on them. In Santa Cruz, California, the police department explicitly sought to use a DHS-funded SHSP grant to pay for a new citywide network of Flock ALPR cameras at the city's entrances and exits, with local funds covering additional cameras. In Sumner, Washington, a $50,000 grant was used to cover the entire first year of a Flock system — including installation and maintenance — after which the city is on the hook for roughly $39,000 every year in ongoing fees. The free grant money opens the door, but local governments are left with years of financial, political, and permanent surveillance entanglements they never fully vetted.

The most dangerous cost of this "free" funding is not just budgetary; it is the way it ties local systems into federal data pipelines. Since 9/11, DHS has used these grant streams to build a nationwide network of at least 79–80 state and regional fusion centers that integrate and share data from federal, state, local, tribal, and private partners. Research shows that state fusion centers rely heavily on the DHS Homeland Security Grant Program (especially SHSP and UASI) to "mature their capabilities," with some centers reporting that 100 percent of their annual expenditures are covered by these grants. 

Civil rights investigations have documented how this funding architecture creates a backdoor channel for ICE and other federal agencies to access local surveillance data for their own purposes. A recent report by the Surveillance Technology Oversight Project (S.T.O.P.) describes ICE agents using a Philadelphia‑area fusion center to query the city’s ALPR network to track undocumented drivers in a self‑described sanctuary city.

Ultimately, federal grants follow the same script as trials and foundation gifts: what looks “free” ends up costing communities their data, their sanctuary protections, and their power over how local surveillance is used.

Protecting Yourself Against “Free” Technology

The most important protection against "free" surveillance technology is to reject it outright. Cities do not have to accept federal grants, vendor trials, or philanthropic donations. Saying no to "free" tech is not just a policy choice; it is a political power that local governments possess and can exercise. Communities and their elected officials can and should refuse surveillance systems that arrive through federal grants, vendor pilots, or private donations, regardless of how attractive the initial price tag appears. 

For those cities that have already accepted surveillance technology, the imperative is equally clear: shut it down. When a community has rejected use of a spying tool, the capabilities, equipment, and data collected from that tool should be shut off immediately. Full stop.

And for any surveillance technology that remains in operation, even temporarily, there must be clear rules: when and how equipment is used, how that data is retained and shared, who owns data and how companies can access and use it, transparency requirements, and consequences for any misuse and abuse. 

“Free” surveillance technology is never free. Someone profits or gains power from it. Police technology vendors, federal agencies, and wealthy donors do not offer these systems out of generosity; they offer them because surveillance serves their interests, not ours. That is the real cost of “free” surveillance.

Kimwolf Botnet Swamps Anonymity Network I2P

11 February 2026 at 17:08

For the past week, the massive “Internet of Things” (IoT) botnet known as Kimwolf has been disrupting The Invisible Internet Project (I2P), a decentralized, encrypted communications network designed to anonymize and secure online communications. I2P users started reporting disruptions in the network around the same time the Kimwolf botmasters began relying on it to evade takedown attempts against the botnet’s control servers.

Kimwolf is a botnet that surfaced in late 2025 and quickly infected millions of systems, turning poorly secured IoT devices like TV streaming boxes, digital picture frames and routers into relays for malicious traffic and abnormally large distributed denial-of-service (DDoS) attacks.

I2P is a decentralized, privacy-focused network that allows people to communicate and share information anonymously.

“It works by routing data through multiple encrypted layers across volunteer-operated nodes, hiding both the sender’s and receiver’s locations,” the I2P website explains. “The result is a secure, censorship-resistant network designed for private websites, messaging, and data sharing.”

On February 3, I2P users began complaining on the organization’s GitHub page about tens of thousands of routers suddenly overwhelming the network, preventing existing users from communicating with legitimate nodes. Users reported a rapidly increasing number of new routers joining the network that were unable to transmit data, and that the mass influx of new systems had overwhelmed the network to the point where users could no longer connect.

I2P users complaining about service disruptions from a rapidly increasing number of routers suddenly swamping the network.

When one I2P user asked whether the network was under attack, another user replied, “Looks like it. My physical router freezes when the number of connections exceeds 60,000.”

A graph shared by I2P developers showing a marked drop in successful connections on the I2P network around the time the Kimwolf botnet started trying to use the network for fallback communications.

The same day that I2P users began noticing the outages, the individuals in control of Kimwolf posted to their Discord channel that they had accidentally disrupted I2P after attempting to join 700,000 Kimwolf-infected bots as nodes on the network.

The Kimwolf botmaster openly discusses what they are doing with the botnet in a Discord channel with my name on it.

Although Kimwolf is known as a potent weapon for launching DDoS attacks, the outages caused this week by some portion of the botnet attempting to join I2P are what’s known as a “Sybil attack,” a threat in peer-to-peer networks where a single entity can disrupt the system by creating, controlling, and operating a large number of fake, pseudonymous identities.

Indeed, the number of Kimwolf-infected routers that tried to join I2P this past week was many times the network’s normal size. I2P’s Wikipedia page says the network consists of roughly 55,000 computers distributed throughout the world, with each participant acting as both a router (to relay traffic) and a client.

However, Lance James, founder of the New York City based cybersecurity consultancy Unit 221B and the original founder of I2P, told KrebsOnSecurity the entire I2P network now consists of between 15,000 and 20,000 devices on any given day.

An I2P user posted this graph on Feb. 10, showing tens of thousands of routers — mostly from the United States — suddenly attempting to join the network.

Benjamin Brundage is founder of Synthient, a startup that tracks proxy services and was the first to document Kimwolf’s unique spreading techniques. Brundage said the Kimwolf operator(s) have been trying to build a command and control network that can’t easily be taken down by security companies and network operators that are working together to combat the spread of the botnet.

Brundage said the people in control of Kimwolf have been experimenting with using I2P and a similar anonymity network — Tor — as a backup command and control network, although there have been no reports of widespread disruptions in the Tor network recently.

“I don’t think their goal is to take I2P down,” he said. “It’s more they’re looking for an alternative to keep the botnet stable in the face of takedown attempts.”

The Kimwolf botnet created challenges for Cloudflare late last year when it began instructing millions of infected devices to use Cloudflare’s domain name system (DNS) settings, causing control domains associated with Kimwolf to repeatedly usurp Amazon, Apple, Google and Microsoft in Cloudflare’s public ranking of the most frequently requested websites.

James said the I2P network is still operating at about half of its normal capacity, and that a new release is rolling out which should bring some stability improvements over the next week for users.

Meanwhile, Brundage said the good news is Kimwolf’s overlords appear to have quite recently alienated some of their more competent developers and operators, leading to a rookie mistake this past week that caused the botnet’s overall numbers to drop by more than 600,000 infected systems.

“It seems like they’re just testing stuff, like running experiments in production,” he said. “But the botnet’s numbers are dropping significantly now, and they don’t seem to know what they’re doing.”

The game is over: when “free” comes at too high a price. What we know about RenEngine

11 February 2026 at 15:00

We often describe cases of malware distribution under the guise of game cheats and pirated software. Sometimes such methods are used to spread complex malware that employs advanced techniques and sophisticated infection chains.

In February 2026, researchers from Howler Cell announced the discovery of a mass campaign distributing pirated games infected with a previously unknown family of malware. It turned out to be a loader called RenEngine, which was delivered to the device using a modified version of the Ren’Py engine-based game launcher. Kaspersky solutions detect the RenEngine loader as Trojan.Python.Agent.nb and HEUR:Trojan.Python.Agent.gen.

However, this threat is not new. Our solutions began detecting the first samples of the RenEngine loader in March 2025, when it was used to distribute the Lumma stealer (Trojan-PSW.Win32.Lumma.gen).

In the ongoing incidents, ACR Stealer (Trojan-PSW.Win32.ACRstealer.gen) is being distributed as the final payload. We have been monitoring this campaign for a long time and will share some details in this article.

Incident analysis

Disguise as a visual novel

Let’s look at the first incident, which we detected in March 2025. At that time, the attackers distributed the malware under the guise of a hacked game on a popular gaming web resource.

The website featured a game download page with two buttons: Free Download Now and Direct Download. Both buttons had the same functionality: they redirected users to the MEGA file-sharing service, where they were offered to download an archive with the “game.”

When the “game” was launched, the download process would stop at 100%. One might think that the game froze, but that was not the case — the “real” malicious code just started working.

“Game” source files analysis

The full infection chain

The full infection chain


After analyzing the source files, we found Python scripts that initiated the initial device infection. These scripts imitated the endless loading of the game. In addition, they contained the is_sandboxed function for bypassing the sandbox and xor_decrypt_file for decrypting the malicious payload. Using the latter, the script decrypts the ZIP archive, unpacks its contents into the .temp directory, and launches the unpacked files.
Contents of the .temp directory

Contents of the .temp directory


There are five files in the .temp directory. The DKsyVGUJ.exe executable is not malicious. Its original name is Ahnenblatt4.exe, and it is a well-known legitimate application for organizing genealogical data. The borlndmm.dll library also does not contain malicious code; it implements the memory manager required to run the executable. Another library, cc32290mt.dll, contains a code snippet patched by attackers that intercepts control when the application is launched and deploys the first stage of the payload in the process memory.

HijackLoader

The dbghelp.dll system library is used as a “container” to launch the first stage of the payload. It is overwritten in memory with decrypted shellcode obtained from the gayal.asp file using the cc32290mt.dll library. The resulting payload is HijackLoader. This is a relatively new means of delivering and deploying malicious implants. A distinctive feature of this malware family is its modularity and configuration flexibility. HijackLoader was first detected and described in the summer of 2023. More detailed information about this loader is available to customers of the Kaspersky Intelligence Reporting Service.

The final payload can be delivered in two ways, depending on the configuration parameters of the malicious sample. The main HijackLoader ti module is used to launch and prepare the process for the final payload injection. In some cases, an additional module is also used, which is injected into an intermediate process launched by the main one. The code that performs the injection is the same in both cases.

Before creating a child process, the configuration parameters are encrypted using XOR and saved to the %TEMP% directory with a random name. The file name is written to the system environment variables.

Loading configuration parameters saved by the main module

In the analyzed sample, the execution follows a longer path with an intermediate child process, cmd.exe. It is created in suspended mode by calling the auxiliary module modCreateProcess. Then, using the ZwCreateSection and ZwMapViewOfSection system API calls, the code of the same dbghelp.dll library is loaded into the address space of the process, after which it intercepts control.

Next, the ti module, launched inside the child process, reads the hap.eml file, from which it decrypts the second stage of HijackLoader. The module then loads the pla.dll system library and overwrites the beginning of its code section with the received payload, after which it transfers control to this library.

Payload decryption

Payload decryption


The decrypted payload is an EXE file, and the configuration parameters are set to inject it into the explorer.exe child process. The payload is written to the memory of the child process in several stages:
  1. First, the malicious payload is written to a temporary file on disk using the transaction mechanism provided by the Windows API. The payload is written in several stages and not in the order in which the data is stored in the file. The MZ signature, with which any PE file begins, is written last with a delay.
    Writing the payload to a temporary file

    Writing the payload to a temporary file

  2. After that, the payload is loaded from the temporary file into the address space of the current process using the ZwCreateSection call. The transaction that wrote to the file is rolled back, thus deleting the temporary file with the payload.
  3. Next, the sample uses the modCreateProcess module to launch the child process explorer.exe and injects the payload into it by creating a shared memory region with the ZwMapViewOfSection call.
    Payload injection into the child process

    Another HijackLoader module, rshell, is used to launch the shellcode. Its contents are also injected into the child process, replacing the code located at its entry point.
    The rshell module injection

    The rshell module injection

  4. The last step performed by the parent process is starting a thread in the child process by calling ZwResumeThread. After that, the thread starts executing the rshell module code placed at the child process entry point, and the parent process terminates.

    The rshell module prepares the final malicious payload. Once it has finished, it transfers control to another HijackLoader module called ESAL. It replaces the contents of rshell with zeros using the memset function and launches the final payload, which is a stealer from the Lumma family (Trojan-PSW.Win32.Lumma).

In addition to the modules described above, this HijackLoader sample contains the following modules, which were used at intermediate stages: COPYLIST, modTask, modUAC, and modWriteFile.
Kaspersky solutions detect HijackLoader with the verdicts Trojan.Win32.Penguish and Trojan.Win32.DllHijacker.

Not only games

In addition to gaming sites, we found that attackers created dozens of different web resources to distribute RenEngine under the guise of pirated software. On one such site, for example, users can supposedly download an activated version of the CorelDRAW graphics editor.

When the user clicks the Descargar Ahora (“Download Now”) button, they are redirected several times to other malicious websites, after which an infected archive is downloaded to their device.

Distribution

According to our data, since March 2025, RenEngine has affected users in the following countries:

Distribution of incidents involving the RenEngine loader by country (TOP 20), February 2026 (download)

The distribution pattern of this loader suggests that the attacks are not targeted. At the time of publication, we have recorded the highest number of incidents in Russia, Brazil, Türkiye, Spain, and Germany.

Recommendations for protection

The format of game archives is generally not standardized and is unique for each game. This means that there is no universal algorithm for unpacking and checking the contents of game archives. If the game engine does not check the integrity and authenticity of executable resources and scripts, such an archive can become a repository for malware if modified by attackers. Despite this, Kaspersky Premium protects against such threats with its Behavior Detection component.

The distribution of malware under the guise of pirated software and hacked games is not a new tactic. It is relatively easy to avoid infection by the malware described in this article: simply install games and programs from trusted sites. In addition, it is important for gamers to remember the need to install specialized security solutions. This ongoing campaign employs the Lumma and ACR stylers, and Vidar was also found — none of these are new threats, but rather long-known malware. This means that modern antivirus technologies can detect even modified versions of the above-mentioned stealers and their alternatives, preventing further infection.

Prompt Injection Via Road Signs

11 February 2026 at 13:03

Interesting research: “CHAI: Command Hijacking Against Embodied AI.”

Abstract: Embodied Artificial Intelligence (AI) promises to handle edge cases in robotic vehicle systems where data is scarce by using common-sense reasoning grounded in perception and action to generalize beyond training distributions and adapt to novel real-world situations. These capabilities, however, also create new security risks. In this paper, we introduce CHAI (Command Hijacking against embodied AI), a new class of prompt-based attacks that exploit the multimodal language interpretation abilities of Large Visual-Language Models (LVLMs). CHAI embeds deceptive natural language instructions, such as misleading signs, in visual input, systematically searches the token space, builds a dictionary of prompts, and guides an attacker model to generate Visual Attack Prompts. We evaluate CHAI on four LVLM agents; drone emergency landing, autonomous driving, and aerial object tracking, and on a real robotic vehicle. Our experiments show that CHAI consistently outperforms state-of-the-art attacks. By exploiting the semantic and multimodal reasoning strengths of next-generation embodied AI systems, CHAI underscores the urgent need for defenses that extend beyond traditional adversarial robustness.

Phishing and scams in 2025

Entertainment-themed phishing attacks and scams

In 2025, online streaming services remained a primary theme for phishing sites within the entertainment sector, typically by offering early access to major premieres ahead of their official release dates. Alongside these, there was a notable increase in phishing pages mimicking ticket aggregation platforms for live events. Cybercriminals lured users with offers of free tickets to see popular artists on pages that mirrored the branding of major ticket distributors. To participate in these “promotions”, victims were required to pay a nominal processing or ticket-shipping fee. Naturally, after paying the fee, the users never received any tickets.

In addition to concert-themed bait, other music-related scams gained significant traction. Users were directed to phishing pages and prompted to “vote for their favorite artist”, a common activity within fan communities. To bolster credibility, the scammers leveraged the branding of major companies like Google and Spotify. This specific scheme was designed to harvest credentials for multiple platforms simultaneously, as users were required to sign in with their Facebook, Instagram, or email credentials to participate.

As a pretext for harvesting Spotify credentials, attackers offered users a way to migrate their playlists to YouTube. To complete the transfer, victims were to just enter their Spotify credentials.

Beyond standard phishing, threat actors leveraged Spotify’s popularity for scams. In Brazil, scammers promoted a scheme where users were purportedly paid to listen to and rate songs.

To “withdraw” their earnings, users were required to provide their identification number for PIX, Brazil’s instant payment system.

Users were then prompted to verify their identity. To do so, the victim was required to make a small, one-time “verification payment”, an amount significantly lower than the potential earnings.

The form for submitting this “verification payment” was designed to appear highly authentic, even requesting various pieces of personal data. It is highly probable that this data was collected for use in subsequent attacks.

In another variation, users were invited to participate in a survey in exchange for a $1000 gift card. However, in a move typical of a scam, the victim was required to pay a small processing or shipping fee to claim the prize. Once the funds were transferred, the attackers vanished, and the website was taken offline.

Even deciding to go to an art venue with a girl from a dating site could result in financial loss. In this scenario, the “date” would suggest an in-person meeting after a brief period of rapport-building. They would propose a relatively inexpensive outing, such as a movie or a play at a niche theater. The scammer would go so far as to provide a link to a specific page where the victim could supposedly purchase tickets for the event.

To enhance the site’s perceived legitimacy, it even prompted the user to select their city of residence.

However, once the “ticket payment” was completed, both the booking site and the individual from the dating platform would vanish.

A similar tactic was employed by scam sites selling tickets for escape rooms. The design of these pages closely mirrored legitimate websites to lower the target’s guard.

Phishing pages masquerading as travel portals often capitalize on a sense of urgency, betting that a customer eager to book a “last-minute deal” will overlook an illegitimate URL. For example, the fraudulent page shown below offered exclusive tours of Japan, purportedly from a major Japanese tour operator.

Sensitive data at risk: phishing via government services

To harvest users’ personal data, attackers utilized a traditional phishing framework: fraudulent forms for document processing on sites posing as government portals. The visual design and content of these phishing pages meticulously replicated legitimate websites, offering the same services found on official sites. In Brazil, for instance, attackers collected personal data from individuals under the pretext of issuing a Rural Property Registration Certificate (CCIR).

Through this method, fraudsters tried to gain access to the victim’s highly sensitive information, including their individual taxpayer registry (CPF) number. This identifier serves as a unique key for every Brazilian national to access private accounts on government portals. It is also utilized in national databases and displayed on personal identification documents, making its interception particularly dangerous. Scammer access to this data poses a severe risk of identity theft, unauthorized access to government platforms, and financial exposure.

Furthermore, users were at risk of direct financial loss: in certain instances, the attackers requested a “processing fee” to facilitate the issuance of the important document.

Fraudsters also employed other methods to obtain CPF numbers. Specifically, we discovered phishing pages mimicking the official government service portal, which requires the CPF for sign-in.

Another theme exploited by scammers involved government payouts. In 2025, Singaporean citizens received government vouchers ranging from $600 to $800 in honor of the country’s 60th anniversary. To redeem these, users were required to sign in to the official program website. Fraudsters rushed to create web pages designed to mimic this site. Interestingly, the primary targets in this campaign were Telegram accounts, despite the fact that Telegram credentials were not a requirement for signing in to the legitimate portal.

We also identified a scam targeting users in Norway who were looking to renew or replace their driver’s licenses. Upon opening a website masquerading as the official Norwegian Public Roads Administration website, visitors were prompted to enter their vehicle registration and phone numbers.

Next, the victim was prompted for sensitive data, such as the personal identification number unique to every Norwegian citizen. By doing so, the attackers not only gained access to confidential information but also reinforced the illusion that the victim was interacting with an official website.

Once the personal data was submitted, a fraudulent page would appear, requesting a “processing fee” of 1200 kroner. If the victim entered their credit card details, the funds were transferred directly to the scammers with no possibility of recovery.

In Germany, attackers used the pretext of filing tax returns to trick users into providing their email user names and passwords on phishing pages.

A call to urgent action is a classic tactic in phishing scenarios. When combined with the threat of losing property, these schemes become highly effective bait, distracting potential victims from noticing an incorrect URL or a poorly designed website. For example, a phishing warning regarding unpaid vehicle taxes was used as a tool by attackers targeting credentials for the UK government portal.

We have observed that since the spring of 2025, there has been an increase in emails mimicking automated notifications from the Russian government services portal. These messages were distributed under the guise of application status updates and contained phishing links.

We also recorded vishing attacks targeting users of government portals. Victims were prompted to “verify account security” by calling a support number provided in the email. To lower the users’ guard, the attackers included fabricated technical details in the emails, such as the IP address, device model, and timestamp of an alleged unauthorized sign-in.

Last year, attackers also disguised vishing emails as notifications from microfinance institutions or credit bureaus regarding new loan applications. The scammers banked on the likelihood that the recipient had not actually applied for a loan. They would then prompt the victim to contact a fake support service via a spoofed support number.

Know Your Customer

As an added layer of data security, many services now implement biometric verification (facial recognition, fingerprints, and retina scans), as well as identity document verification and digital signatures. To harvest this data, fraudsters create clones of popular platforms that utilize these verification protocols. We have previously detailed the mechanics of this specific type of data theft.

In 2025, we observed a surge in phishing attacks targeting users under the guise of Know Your Customer (KYC) identity verification. KYC protocols rely on a specific set of user data for identification. By spoofing the pages of payment services such as Vivid Money, fraudsters harvested the information required to pass KYC authentication.

Notably, this threat also impacted users of various other platforms that utilize KYC procedures.

A distinctive feature of attacks on the KYC process is that, in addition to the victim’s full name, email address, and phone number, phishers request photos of their passport or face, sometimes from multiple angles. If this information falls into the hands of threat actors, the consequences extend beyond the loss of account access; the victim’s credentials can be sold on dark web marketplaces, a trend we have highlighted in previous reports.

Messaging app phishing

Account hijacking on messaging platforms like WhatsApp and Telegram remains one of the primary objectives of phishing and scam operations. While traditional tactics, such as suspicious links embedded in messages, have been well-known for some time, the methods used to steal credentials are becoming increasingly sophisticated.

For instance, Telegram users were invited to participate in a prize giveaway purportedly hosted by a famous athlete. This phishing attack, which masqueraded as an NFT giveaway, was executed through a Telegram Mini App. This marks a shift in tactics, as attackers previously relied on external web pages for these types of schemes.

In 2025, new variations emerged within the familiar framework of distributing phishing links via Telegram. For example, we observed prompts inviting users to vote for the “best dentist” or “best COO” in town.

The most prevalent theme in these voting-based schemes, children’s contests, was distributed primarily through WhatsApp. These phishing pages showed little variety; attackers utilized a standardized website design and set of “bait” photos, simply localizing the language based on the target audience’s geographic location.

To participate in the vote, the victim was required to enter the phone number linked to their WhatsApp account.

They were then prompted to provide a one-time authentication code for the messaging app.

The following are several other popular methods used by fraudsters to hijack user credentials.

In China, phishing pages meticulously replicated the WhatsApp interface. Victims were notified that their accounts had purportedly been flagged for “illegal activity”, necessitating “additional verification”.

The victim was redirected to a page to enter their phone number, followed by a request for their authorization code.

In other instances, users received messages allegedly from WhatsApp support regarding account authentication via SMS. As with the other scenarios described, the attackers’ objective was to obtain the authentication code required to hijack the account.

Fraudsters enticed WhatsApp users with an offer to link an app designed to “sync communications” with business contacts.

To increase the perceived legitimacy of the phishing site, the attackers even prompted users to create custom credentials for the page.

After that, the user was required to “purchase a subscription” to activate the application. This allowed the scammers to harvest credit card data, leaving the victim without the promised service.

To lure Telegram users, phishers distributed invitations to online dating chats.

Attackers also heavily leveraged the promise of free Telegram Premium subscriptions. While these phishing pages were previously observed only in Russian and English, the linguistic scope of these campaigns expanded significantly this year. As in previous iterations, activating the subscription required the victim to sign in to their account, which could result in the loss of account access.

Exploiting the ChatGPT hype

Artificial intelligence is increasingly being leveraged by attackers as bait. For example, we have identified fraudulent websites mimicking the official payment page for ChatGPT Plus subscriptions.

Social media marketing through LLMs was also a potential focal point for user interest. Scammers offered “specialized prompt kits” designed for social media growth; however, once payment was received, they vanished, leaving victims without the prompts or their money.

The promise of easy income through neural networks has emerged as another tactic to attract potential victims. Fraudsters promoted using ChatGPT to place bets, promising that the bot would do all the work while the user collected the profits. These services were offered at a “special price” valid for only 15 minutes after the page was opened. This narrow window prevented the victim from critically evaluating the impulse purchase.

Job opportunities with a catch

To attract potential victims, scammers exploited the theme of employment by offering high-paying remote positions. Applicants responding to these advertisements did more than just disclose their personal data; in some cases, fraudsters requested a small sum under the pretext of document processing or administrative fees. To convince victims that the offer was legitimate, attackers impersonated major brands, leveraging household names to build trust. This allowed them to lower the victims’ guard, even when the employment terms sounded too good to be true.

We also observed schemes where, after obtaining a victim’s data via a phishing site, scammers would follow up with a phone call – a tactic aimed at tricking the user into disclosing additional personal data.

By analyzing current job market trends, threat actors also targeted popular career paths to steal messaging app credentials. These phishing schemes were tailored to specific regional markets. For example, in the UAE, fake “employment agency” websites were circulating.

In a more sophisticated variation, users were asked to complete a questionnaire that required the phone number linked to their Telegram account.

To complete the registration, users were prompted for a code which, in reality, was a Telegram authorization code.

Notably, the registration process did not end there; the site continued to request additional information to “set up an account” on the fraudulent platform. This served to keep victims in the dark, maintaining their trust in the malicious site’s perceived legitimacy.

After finishing the registration, the victim was told to wait 24 hours for “verification”, though the scammers’ primary objective, hijacking the Telegram account, had already been achieved.

Simpler phishing schemes were also observed, where users were redirected to a page mimicking the Telegram interface. By entering their phone number and authorization code, victims lost access to their accounts.

Job seekers were not the only ones targeted by scammers. Employers’ accounts were also in the crosshairs, specifically on a major Russian recruitment portal. On a counterfeit page, the victim was asked to “verify their account” in order to post a job listing, which required them to enter their actual sign-in credentials for the legitimate site.

Spam in 2025

Malicious attachments

Password-protected archives

Attackers began aggressively distributing messages with password-protected malicious archives in 2024. Throughout 2025, these archives remained a popular vector for spreading malware, and we observed a variety of techniques designed to bypass security solutions.

For example, threat actors sent emails impersonating law firms, threatening victims with legal action over alleged “unauthorized domain name use”. The recipient was prompted to review potential pre-trial settlement options detailed in an attached document. The attachment consisted of an unprotected archive containing a secondary password-protected archive and a file with the password. Disguised as a legal document within this inner archive was a malicious WSF file, which installed a Trojan into the system via startup. The Trojan then stealthily downloaded and installed Tor, which allowed it to regularly exfiltrate screenshots to the attacker-controlled C2 server.

In addition to archives, we also encountered password-protected PDF files containing malicious links over the past year.

E-signature service exploits

Emails using the pretext of “signing a document” to coerce users into clicking phishing links or opening malicious attachments were quite common in 2025. The most prevalent scheme involved fraudulent notifications from electronic signature services. While these were primarily used for phishing, one specific malware sample identified within this campaign is of particular interest.

The email, purportedly sent from a well-known document-sharing platform, notified the recipient that they had been granted access to a “contract” attached to the message. However, the attachment was not the expected PDF; instead, it was a nested email file named after the contract. The body of this nested message mirrored the original, but its attachment utilized a double extension: a malicious SVG file containing a Trojan was disguised as a PDF document. This multi-layered approach was likely an attempt to obfuscate the malware and bypass security filters.

“Business correspondence” impersonating industrial companies

In the summer of last year, we observed mailshots sent in the name of various existing industrial enterprises. These emails contained DOCX attachments embedded with Trojans. Attackers coerced victims into opening the malicious files under the pretext of routine business tasks, such as signing a contract or drafting a report.

The authors of this malicious campaign attempted to lower users’ guard by using legitimate industrial sector domains in the “From” address. Furthermore, the messages were routed through the mail servers of a reputable cloud provider, ensuring the technical metadata appeared authentic. Consequently, even a cautious user could mistake the email for a genuine communication, open the attachment, and compromise their device.

Attacks on hospitals

Hospitals were a popular target for threat actors this past year: they were targeted with malicious emails impersonating well-known insurance providers. Recipients were threatened with legal action regarding alleged “substandard medical services”. The attachments, described as “medical records and a written complaint from an aggrieved patient”, were actually malware. Our solutions detect this threat as Backdoor.Win64.BrockenDoor, a backdoor capable of harvesting system information and executing malicious commands on the infected device.

We also came across emails with a different narrative. In those instances, medical staff were requested to facilitate a patient transfer from another hospital for ongoing observation and treatment. These messages referenced attached medical files containing diagnostic and treatment history, which were actually archives containing malicious payloads.

To bolster the perceived legitimacy of these communications, attackers did more than just impersonate famous insurers and medical institutions; they registered look-alike domains that mimicked official organizations’ domains by appending keywords such as “-insurance” or “-med.” Furthermore, to lower the victims’ guard, scammers included a fake “Scanned by Email Security” label.

Messages containing instructions to run malicious scripts

Last year, we observed unconventional infection chains targeting end-user devices. Threat actors continued to distribute instructions for downloading and executing malicious code, rather than attaching the malware files directly. To convince the recipient to follow these steps, attackers typically utilized a lure involving a “critical software update” or a “system patch” to fix a purported vulnerability. Generally, the first step in the instructions required launching the command prompt with administrative privileges, while the second involved entering a command to download and execute the malware: either a script or an executable file.

In some instances, these instructions were contained within a PDF file. The victim was prompted to copy a command into PowerShell that was neither obfuscated nor hidden. Such schemes target non-technical users who would likely not understand the command’s true intent and would unknowingly infect their own devices.

Scams

Law enforcement impersonation scams in the Russian web segment

In 2025, extortion campaigns involving actors posing as law enforcement – a trend previously more prevalent in Europe – were adapted to target users across the Commonwealth of Independent States.

For example, we identified messages disguised as criminal subpoenas or summonses purportedly issued by Russian law enforcement agencies. However, the specific departments cited in these emails never actually existed. The content of these “summonses” would also likely raise red flags for a cautious user. This blackmail scheme relied on the victim, in their state of panic, not scrutinizing the contents of the fake summons.

To intimidate recipients, the attackers referenced legal frameworks and added forged signatures and seals to the “subpoenas”. In reality, neither the cited statutes nor the specific civil service positions exist in Russia.

We observed similar attacks – employing fabricated government agencies and fictitious legal acts – in other CIS countries, such as Belarus.

Fraudulent investment schemes

Threat actors continued to aggressively exploit investment themes in their email scams. These emails typically promise stable, remote income through “exclusive” investment opportunities. This remains one of the most high-volume and adaptable categories of email scams. Threat actors embedded fraudulent links both directly within the message body and inside various types of attachments: PDF, DOC, PPTX, and PNG files. Furthermore, they increasingly leveraged legitimate Google services, such as Google Docs, YouTube, and Google Forms, to distribute these communications. The link led to the site of the “project” where the victim was prompted to provide their phone number and email. Subsequently, users were invited to invest in a non-existent project.

We have previously documented these mailshots: they were originally targeted at Russian-speaking users and were primarily distributed under the guise of major financial institutions. However, in 2025, this investment-themed scam expanded into other CIS countries and Europe. Furthermore, the range of industries that spammers impersonated grew significantly. For instance, in their emails, attackers began soliciting investments for projects supposedly led by major industrial-sector companies in Kazakhstan and the Czech Republic.

Fraudulent “brand partner” recruitment

This specific scam operates through a multi-stage workflow. First, the target company receives a communication from an individual claiming to represent a well-known global brand, inviting them to register as a certified supplier or business partner. To bolster the perceived authenticity of the offer, the fraudsters send the victim an extensive set of forged documents. Once these documents are signed, the victim is instructed to pay a “deposit”, which the attackers claim will be fully refunded once the partnership is officially established.

These mailshots were first detected in 2025 and have rapidly become one of the most prevalent forms of email-based fraud. In December 2025 alone, we blocked over 80,000 such messages. These campaigns specifically targeted the B2B sector and were notable for their high level of variation – ranging from their technical properties to the diversity of the message content and the wide array of brands the attackers chose to impersonate.

Fraudulent overdue rent notices

Last year, we identified a new theme in email scams: recipients were notified that the payment deadline for a leased property had expired and were urged to settle the “debt” immediately. To prevent the victim from sending funds to their actual landlord, the email claimed that banking details had changed. The “debtor” was then instructed to request the new payment information – which, of course, belonged to the fraudsters. These mailshots primarily targeted French-speaking countries; however, in December 2025, we discovered a similar scam variant in German.

QR codes in scam letters

In 2025, we observed a trend where QR codes were utilized not only in phishing attempts but also in extortion emails. In a classic blackmail scam, the user is typically intimidated by claims that hackers have gained access to sensitive data. To prevent the public release of this information, the attackers demand a ransom payment to their cryptocurrency wallet.

Previously, to bypass email filters, scammers attempted to obfuscate the wallet address by using various noise contamination techniques. In last year’s campaigns, however, scammers shifted to including a QR code that contained the cryptocurrency wallet address.

News agenda

As in previous years, spammers in 2025 aggressively integrated current events into their fraudulent messaging to increase engagement.

For example, following the launch of $TRUMP memecoins surrounding Donald Trump’s inauguration, we identified scam campaigns promoting the “Trump Meme Coin” and “Trump Digital Trading Cards”. In these instances, scammers enticed victims to click a link to claim “free NFTs”.

We also observed ads offering educational credentials. Spammers posted these ads as comments on legacy, unmoderated forums; this tactic ensured that notifications were automatically pushed to all users subscribed to the thread. These notifications either displayed the fraudulent link directly in the comment preview or alerted users to a new post that redirected them to spammers’ sites.

In the summer, when the wedding of Amazon founder Jeff Bezos became a major global news story, users began receiving Nigerian-style scam messages purportedly from Bezos himself, as well as from his former wife, MacKenzie Scott. These emails promised recipients substantial sums of money, framed either as charitable donations or corporate compensation from Amazon.

During the BLACKPINK world tour, we observed a wave of spam advertising “luggage scooters”. The scammers claimed these were the exact motorized suitcases used by the band members during their performances.

Finally, in the fall of 2025, traditionally timed to coincide with the launch of new iPhones, we identified scam campaigns featuring surveys that offered participants a chance to “win” a fictitious iPhone 17 Pro.

After completing a brief survey, the user was prompted to provide their contact information and physical address, as well as pay a “delivery fee” – which was the scammers’ ultimate objective. Upon entering their credit card details into the fraudulent site, the victim risked losing not only the relatively small delivery charge but also the entire balance in their bank account.

The widespread popularity of Ozempic was also reflected in spam campaigns; users were bombarded with offers to purchase versions of the drug or questionable alternatives.

Localized news events also fall under the scrutiny of fraudsters, serving as the basis for scam narratives. For instance, last summer, coinciding with the opening of the tax season in South Africa, we began detecting phishing emails impersonating the South African Revenue Service (SARS). These messages notified taxpayers of alleged “outstanding balances” that required immediate settlement.

Methods of distributing email threats

Google services

In 2025, threat actors increasingly leveraged various Google services to distribute email-based threats. We observed the exploitation of Google Calendar: scammers would create an event containing a WhatsApp contact number in the description and send an invitation to the target. For instance, companies received emails regarding product inquiries that prompted them to move the conversation to the messaging app to discuss potential “collaboration”.

Spammers employed a similar tactic using Google Classroom. We identified samples offering SEO optimization services that likewise directed victims to a WhatsApp number for further communication.

We also detected the distribution of fraudulent links via legitimate YouTube notifications. Attackers would reply to user comments under various videos, triggering an automated email notification to the victim. This email contained a link to a video that displayed only a message urging the viewer to “check the description”, where the actual link to the scam site was located. As the victim received an email containing the full text of the fraudulent comment, they were often lured through this chain of links, eventually landing on the scam site.

Over the past two years or so, there has been a significant rise in attacks utilizing Google Forms. Fraudsters create a survey with an enticing title and place the scam messaging directly in the form’s description. They then submit the form themselves, entering the victims’ email addresses into the field for the respondent email. This triggers legitimate notifications from the Google Forms service to the targeted addresses. Because these emails originate from Google’s own mail servers, they appear authentic to most spam filters. The attackers rely on the victim focusing on the “bait” description containing the fraudulent link rather than the standard form header.

Google Groups also emerged as a popular tool for spam distribution last year. Scammers would create a group, add the victims’ email addresses as members, and broadcast spam through the service. This scheme proved highly effective: even if a security solution blocked the initial spam message, the user could receive a deluge of automated replies from other addresses on the member list.

At the end of 2025, we encountered a legitimate email in terms of technical metadata that was sent via Google and contained a fraudulent link. The message also included a verification code for the recipient’s email address. To generate this notification, scammers filled out the account registration form in a way that diverted the recipient’s attention toward a fraudulent site. For example, instead of entering a first and last name, the attackers inserted text such as “Personal Link” followed by a phishing URL, utilizing noise contamination techniques. By entering the victim’s email address into the registration field, the scammers triggered a legitimate system notification containing the fraudulent link.

OpenAI

In addition to Google services, spammers leveraged other platforms to distribute email threats, notably OpenAI, riding the wave of artificial intelligence popularity. In 2025, we observed emails sent via the OpenAI platform into which spammers had injected short messages, fraudulent links, or phone numbers.

This occurs during the account registration process on the OpenAI platform, where users are prompted to create an organization to generate an API key. Spammers placed their fraudulent content directly into the field designated for the organization’s name. They then added the victims’ email addresses as organization members, triggering automated platform invitations that delivered the fraudulent links or contact numbers directly to the targets.

Spear phishing and BEC attacks in 2025

QR codes

The use of QR codes in spear phishing has become a conventional tactic that threat actors continued to employ throughout 2025. Specifically, we observed the persistence of a major trend identified in our previous report: the distribution of phishing documents disguised as notifications from a company’s HR department.

In these campaigns, attackers impersonated HR team members, requesting that employees review critical documentation, such as a new corporate policy or code of conduct. These documents were typically attached to the email as PDF files.

Phishing notification about "new corporate policies"

Phishing notification about “new corporate policies”

To maintain the ruse, the PDF document contained a highly convincing call to action, prompting the user to scan a QR code to access the relevant file. While attackers previously embedded these codes directly into the body of the email, last year saw a significant shift toward placing them within attachments – most likely in an attempt to bypass email security filters.

Malicious PDF content

Upon scanning the QR code within the attachment, the victim was redirected to a phishing page meticulously designed to mimic a Microsoft authentication form.

In addition to fraudulent HR notifications, threat actors created scheduled meetings within the victim’s email calendar, placing DOC or PDF files containing QR codes in the event descriptions. Leveraging calendar invites to distribute malicious links is a legacy technique that was widely observed during scam campaigns in 2019. After several years of relative dormancy, we saw a resurgence of this technique last year, now integrated into more sophisticated spear phishing operations.

Fake meeting invitation

In one specific example, the attachment was presented as a “new voicemail” notification. To listen to the recording, the user was prompted to scan a QR code and sign in to their account on the resulting page.

Malicious attachment content

As in the previous scenario, scanning the code redirected the user to a phishing page, where they risked losing access to their Microsoft account or internal corporate sites.

Link protection services

Threat actors utilized more than just QR codes to hide phishing URLs and bypass security checks. In 2025, we discovered that fraudsters began weaponizing link protection services for the same purpose. The primary function of these services is to intercept and scan URLs at the moment of clicking to prevent users from reaching phishing sites or downloading malware. However, attackers are now abusing this technology by generating phishing links that security systems mistakenly categorize as “safe”.

This technique is employed in both mass and spear phishing campaigns. It is particularly dangerous in targeted attacks, which often incorporate employees’ personal data and mimic official corporate branding. When combined with these characteristics, a URL generated through a legitimate link protection service can significantly bolster the perceived authenticity of a phishing email.

After opening a URL that seemed safe, the user was directed to a phishing site.

BEC and fabricated email chains

In Business Email Compromise (BEC) attacks, threat actors have also begun employing new techniques, the most notable of which is the use of fake forwarded messages.

BEC email featuring a fabricated message thread

BEC email featuring a fabricated message thread

This BEC attack unfolded as follows. An employee would receive an email containing a previous conversation between the sender and another colleague. The final message in this thread was typically an automated out-of-office reply or a request to hand off a specific task to a new assignee. In reality, however, the entire initial conversation with the colleague was completely fabricated. These messages lacked the thread-index headers, as well as other critical header values, that would typically verify the authenticity of an actual email chain.

In the example at hand, the victim was pressured to urgently pay for a license using the provided banking details. The PDF attachments included wire transfer instructions and a counterfeit cover letter from the bank.

Statistics: phishing

In 2025, Kaspersky solutions blocked 554,002,207 attempts to follow fraudulent links. In contrast to the trends of previous years, we did not observe any major spikes in phishing activity; instead, the volume of attacks remained relatively stable throughout the year, with the exception of a minor decline in December.

Anti-Phishing triggers, 2025 (download)

The phishing and scam landscape underwent a shift. While in 2024, we saw a high volume of mass attacks, their frequency declined in 2025. Furthermore, redirection-based schemes, which were frequently used for online fraud in 2024, became less prevalent in 2025.

Map of phishing attacks

As in the previous year, Peru remains the country with the highest percentage (17.46%) of users targeted by phishing attacks. Bangladesh (16.98%) took second place, entering the TOP 10 for the first time, while Malawi (16.65%), which was absent from the 2024 rankings, was third. Following these are Tunisia (16.19%), Colombia (15.67%), the latter also being a newcomer to the TOP 10, Brazil (15.48%), and Ecuador (15.27%). They are followed closely by Madagascar and Kenya, both with a 15.23% share of attacked users. Rounding out the list is Vietnam, which previously held the third spot, with a share of 15.05%.

Top-level domains

In 2025, breaking a trend that had persisted for several years, the majority of phishing pages were hosted within the XYZ TLD zone, accounting for 21.64% – a three-fold increase compared to 2024. The second most popular zone was TOP (15.45%), followed by BUZZ (13.58%). This high demand can be attributed to the low cost of domain registration in these zones. The COM domain, which had previously held the top spot consistently, fell to fourth place (10.52%). It is important to note that this decline is partially driven by the popularity of typosquatting attacks: threat actors frequently spoof sites within the COM domain by using alternative suffixes, such as example-com.site instead of example.com. Following COM is the BOND TLD, entering the TOP 10 for the first time with a 5.56% share. As this zone is typically associated with financial websites, the surge in malicious interest there is a logical progression for financial phishing. The sixth and seventh positions are held by ONLINE (3.39%) and SITE (2.02%), which occupied the fourth and fifth spots, respectively, in 2024. In addition, three domain zones that had not previously appeared in our statistics emerged as popular hosting environments for phishing sites. These included the CFD domain (1.97%), typically used for websites in the clothing, fashion, and design sectors; the Polish national top-level domain, PL (1.75%); and the LOL domain (1.60%).

Organizations targeted by phishing attacks

The rankings of organizations targeted by phishers are based on detections by the Anti-Phishing deterministic component on user computers. The component detects all pages with phishing content that the user has tried to open by following a link in an email message or on the web, as long as links to these pages are present in the Kaspersky database.

Phishing pages impersonating web services (27.42%) and global internet portals (15.89%) maintained their positions in the TOP 10, continuing to rank first and second, respectively. Online stores (11.27%), a traditional favorite among threat actors, returned to the third spot. In 2025, phishers showed increased interest in online gamers: websites mimicking gaming platforms jumped from ninth to fifth place (7.58%). These are followed by banks (6.06%), payment systems (5.93%), messengers (5.70%), and delivery services (5.06%). Phishing attacks also targeted social media (4.42%) and government services (1.77%) accounts.

Statistics: spam

Share of spam in email traffic

In 2025, the average share of spam in global email traffic was 44.99%, representing a decrease of 2.28 percentage points compared to the previous year. Notably, contrary to the trends of the past several years, the fourth quarter was the busiest one: an average of 49.26% of emails were categorized as spam, with peak activity occurring in November (52.87%) and December (51.80%). Throughout the rest of the year, the distribution of junk mail remained relatively stable without significant spikes, maintaining an average share of approximately 43.50%.

In the Russian web segment (Runet), we observed a more substantial decline: the average share of spam decreased by 5.3 percentage points to 43.27%. Deviating from the global trend, the fourth quarter was the quietest period in Russia, with a share of 41.28%. We recorded the lowest level of spam activity in December, when only 36.49% of emails were identified as junk. January and February were also relatively calm, with average values of 41.94% and 43.09%, respectively. Conversely, the Runet figures for March–October correlated with global figures: no major surges were observed, spam accounting for an average of 44.30% of total email traffic during these months.

Countries and territories where spam originated

The top three countries in the 2025 rankings for the volume of outgoing spam mirror the distribution of the previous year: Russia, China, and the United States. However, the share of spam originating from Russia decreased from 36.18% to 32.50%, while the shares of China (19.10%) and the U.S. (10.57%) each increased by approximately 2 percentage points. Germany rose to fourth place (3.46%), up from sixth last year, displacing Kazakhstan (2.89%). Hong Kong followed in sixth place (2.11%). The Netherlands and Japan shared the next spot with identical shares of 1.95%; however, we observed a year-over-year increase in outgoing spam from the Netherlands, whereas Japan saw a decline. The TOP 10 is rounded out by Brazil (1.94%) and Belarus (1.74%), the latter ranking for the first time.

Malicious email attachments

In 2025, Kaspersky solutions blocked 144,722,674 malicious email attachments, an increase of nineteen million compared to the previous year. The beginning and end of the year were traditionally the most stable periods; however, we also observed a notable decline in activity during August and September. Peaks in email antivirus detections occurred in June, July, and November.

Email antivirus detections, 2025 (download)

The most prevalent malicious email attachment in 2025 was the Makoob Trojan family, which covertly harvests system information and user credentials. Makoob first entered the TOP 10 in 2023 in eighth place, rose to third in 2024, and secured the top spot in 2025 with a share of 4.88%. Following Makoob, as in the previous year, was the Badun Trojan family (4.13%), which typically disguises itself as electronic documents. The third spot is held by the Taskun family (3.68%), which creates malicious scheduled tasks, followed by Agensla stealers (3.16%), which were the most common malicious attachments in 2024. Next are Trojan.Win32.AutoItScript scripts (2.88%), appearing in the rankings for the first time. In sixth place is the Noon spyware for all Windows systems (2.63%), which also occupied the tenth spot with its variant specifically targeting 32-bit systems (1.10%). Rounding out the TOP 10 are Hoax.HTML.Phish (1.98%) phishing attachments, Guloader downloaders (1.90%) – a newcomer to the rankings – and Badur (1.56%) PDF documents containing suspicious links.

The distribution of specific malware samples traditionally mirrors the distribution of malware families almost exactly. The only differences are that a specific variant of the Agensla stealer ranked sixth instead of fourth (2.53%), and the Phish and Guloader samples swapped positions (1.58% and 1.78%, respectively). Rounding out the rankings in tenth place is the password stealer Trojan-PSW.MSIL.PureLogs.gen with a share of 1.02%.

Countries and territories targeted by malicious mailings

The highest volume of malicious email attachments was blocked on devices belonging to users in China (13.74%). For the first time in two years, Russia dropped to second place with a share of 11.18%. Following closely behind are Mexico (8.18%) and Spain (7.70%), which swapped places compared to the previous year.

Conclusion

2026 will undoubtedly be marked by novel methods of exploiting artificial intelligence capabilities. At the same time, messaging app credentials will remain a highly sought-after prize for threat actors. While new schemes are certain to emerge, they will likely supplement rather than replace time-tested tricks and tactics. This underscores the reality that, alongside the deployment of robust security software, users must remain vigilant and exercise extreme caution toward any online offers that raise even the slightest suspicion.

The intensified focus on government service credentials signals a rise in potential impact; unauthorized access to these services can lead to financial theft, data breaches, and full-scale identity theft. Furthermore, the increased abuse of legitimate tools and the rise of multi-stage attacks – which often begin with seemingly harmless files or links – demonstrate a concerted effort by fraudsters to lull users into a false sense of security while pursuing their malicious objectives.
