AWS European Sovereign Cloud achieves first compliance milestone: SOC 2 and C5 reports plus seven ISO certifications

In January 2026, we announced the general availability of the AWS European Sovereign Cloud, a new, independent cloud for Europe entirely located within the European Union (EU), and physically and logically separate from all other AWS Regions. The unique approach of the AWS European Sovereign Cloud provides the only fully featured, independently operated sovereign cloud backed by strong technical controls, sovereign assurances, and legal protections designed to meet the sensitive data needs of European governments and enterprises.

One of the foundational components of how AWS European Sovereign Cloud enables verifiable trust of technical controls and delivers assurance is through our compliance programs and assurance frameworks. These programs help customers understand the robust controls in place at AWS European Sovereign Cloud to maintain security and compliance of the cloud. To meet the needs of our customers, we committed that the AWS European Sovereign Cloud will maintain key certifications such as ISO/IEC 27001:2022, System and Organization Controls (SOC) reports, and Cloud Computing Compliance Criteria Catalogue (C5) attestation, all validated regularly by independent auditors to assure our controls are designed appropriately, operate effectively, and can help customers satisfy their compliance obligations.

Today, AWS European Sovereign Cloud is pleased to announce that SOC 2 and C5 Type 1 attestation reports, along with seven key ISO certifications (ISO 27001:2022, 27017:2015, 27018:2019, 27701:2019, 22301:2019, 20000-1:2018, and 9001:2015) are now available. These attestation reports and certifications cover 69 AWS services operating within the AWS European Sovereign Cloud, and this achievement marks a pivotal first step in our journey to establish the AWS European Sovereign Cloud as a trusted and compliant cloud for European organizations. By securing these foundational certifications and attestation reports early in our implementation, we are demonstrating our commitment to earning customer trust. AWS European Sovereign Cloud customers in Germany and across Europe can now run their applications with enhanced assurance and confidence that our infrastructure aligns with internationally recognized security standards and the AWS European Sovereign Cloud: Sovereign Reference Framework (ESC-SRF). These certifications and attestation reports provide independent validation of our security controls and operational practices, demonstrating our commitment to meeting the heightened expectations towards cloud service providers. Beyond compliance, these certifications and reports help customers meet regulatory requirements and innovate with confidence.

SOC 2 Type 1 report

SOC reports are independent third-party examinations that show how AWS European Sovereign Cloud meets compliance controls and sovereignty objectives. The AWS European Sovereign Cloud SOC 2 report addresses three critical AICPA Trust Services Criteria: Security, Availability, and Confidentiality and includes internal controls mapped to the ESC-SRF. The ESC-SRF establishes sovereignty criteria across key domains including governance independence, operational control, data residency, and technical isolation. As part of the SOC 2 Type 1 attestation, independent third-party auditors have validated suitability of the design and implementation of our controls addressing measures such as independent European Union (EU) corporate structures, operation by EU-resident AWS personnel, strict residency requirements for Customer Content and Customer-Created Metadata, and separation from all other AWS Regions. The ESC-SRF controls in our SOC 2 report show customers how AWS delivers on its sovereignty commitments.

C5 Type 1 report

C5 is a German Government-backed attestation scheme introduced in Germany by the Federal Office for Information Security (BSI) and represents one of the most comprehensive cloud security standards in Europe. The AWS European Sovereign Cloud C5 Type 1 report provides customers with independent third-party attestation on the suitability of the design and implementation of our controls to meet both C5 basic criteria and C5 additional criteria.

The basic criteria establish fundamental security requirements for cloud service providers, covering areas such as organization of information security, human resources security, asset management, access control, cryptography, physical security, operations security, communications security, system acquisition and development, supplier relationships, incident management, business continuity, and compliance. The additional criteria address enhanced requirements for handling sensitive data and critical applications, making this attestation particularly valuable for AWS European Sovereign Cloud customers with stringent data security and sovereignty requirements.

Key ISO certifications

AWS European Sovereign Cloud has achieved seven key ISO certifications that collectively demonstrate comprehensive operational excellence:

These certifications confirm that AWS European Sovereign Cloud has integrated rigorous security, privacy, continuity, service delivery, and quality programs into a comprehensive framework, helping to ensure sensitive information remains secure, services remain available, and operations meet the highest standards through systematic risk management processes and continuous improvement practices.

How to access the reports

To access SOC 2, C5 reports and ISO certifications, customers should sign in to their AWS European Sovereign Cloud account and navigate to AWS Artifact in the AWS Management Console. AWS Artifact is a self-service portal that provides on-demand access to AWS compliance reports and certifications.

We recognize that compliance is not a destination but a continuous journey, and these initial SOC 2, C5 reports and ISO certifications represent the beginning of our certification portfolio. They lay the essential groundwork upon which we will continue to build to meet AWS European Sovereign Cloud customers’ compliance needs as they continue to evolve. As we expand our compliance coverage in the months ahead, customers can be confident that security, transparency, and regulatory alignment have been part of the very DNA of the AWS European Sovereign Cloud design from day one.

9th March – Threat Intelligence Report

For the latest discoveries in cyber research for the week of 9th March, please download our Threat Intelligence Bulletin.

TOP ATTACKS AND BREACHES

  • AkzoNobel, a Netherlands-based global paint manufacturer, has confirmed a cyberattack affecting one of its United States sites. The company said the intrusion was contained, while the Anubis ransomware group claimed it stole 170 GB of data, including employee and financial records.
  • LexisNexis, a global legal data and analytics provider, has suffered a breach. Attackers claimed they stole 3.9 million records, including about 400,000 user profiles and some government accounts, while the company said the exposed systems mainly held legacy pre-2020 data.
  • The Wikimedia Foundation, the nonprofit behind Wikipedia, has faced a self-propagating JavaScript worm that vandalized pages and replaced editor scripts across multiple wikis. Engineers briefly restricted editing while cleaning up the incident, with about 3,996 pages modified and roughly 85 users’ personal scripts affected.
  • TriZetto Provider Solutions, an American healthcare technology company owned by Cognizant, has disclosed a breach affecting more than 3.4 million people. The exposed data includes insurance and medical information, with notifications issued this week after investigators determined the unauthorized access began in 2024.

AI THREATS

  • Researchers outlined how Pakistan-linked APT36 has used AI coding tools to produce large volumes of low-quality malware aimed at Indian government entities and embassies. The group generated variants in less common programming languages and used legitimate cloud services for command channels, complicating detection and response.
  • Researchers uncovered AI-themed Chrome and Edge extensions that harvest LLM chat histories and browsing activity. Distributed via the Chrome Web Store, they impersonate legitimate tools and have impacted 900,000 users across 20,000 enterprise environments.
  • Researchers tracked a campaign abusing interest in OpenClaw, an AI agent, by planting fake installers on GitHub that appeared in Bing search results. The installers delivered Vidar to steal credentials and cryptocurrency wallets and sometimes deployed GhostSocks, turning infected systems into residential proxies.
  • Researchers demonstrated indirect prompt injection campaigns against AI agents that read web content, cataloging 22 techniques across live sites. Hidden instructions can redirect agents to expose data, perform unauthorized transactions, and run server commands, and the researchers also observed a real-world bypass of an AI ad review system.

VULNERABILITIES AND PATCHES

  • Google has published patches for CVE-2026-0628, a high-severity vulnerability in Chrome’s Gemini AI panel that allowed malicious extensions to inject code and access cameras and microphones. Researchers showed attackers could also take screenshots, access local files, and launch phishing content inside the panel.
  • A patch was released for CVE-2026-1492, a critical (9.8 CVSS) privilege escalation flaw in the User Registration & Membership WordPress plugin. The vulnerability lets unauthenticated attackers create administrator accounts and take over sites.
  • VMware has patched CVE-2026-22719, a high-severity command injection flaw in Aria Operations, its cloud management platform. The vulnerability allows unauthenticated remote code execution during support-assisted migrations and affects versions 8 through 8.18.5 and 9 through 9.0.1, with patches and a workaround script available.
  • Qualcomm has addressed CVE-2026-21385, a memory corruption vulnerability affecting chipsets used in Android phones, tablets, and IoT devices. The flaw can trigger crashes and potentially allow code execution, and CISA said evidence of active exploitation prompted its addition to the Known Exploited Vulnerabilities catalog.

THREAT INTELLIGENCE REPORTS

  • Check Point Research have mapped Iran-linked cyber clusters conducting espionage, disruption, and influence operations, including Cotton Sandstorm, Educated Manticore, MuddyWater, Handala, and Agrius. Recent campaigns used impersonation and phishing to steal credentials, remote access tools to persist, and wipers or fake ransomware for impact.
  • Check Point Research revealed that, amid the ongoing conflict with Iran, IP cameras in Israel, Qatar, Bahrain, Kuwait, the UAE, and Cyprus have been intensively targeted. Notably, these countries have also experienced significant missile activity from Iran. The findings align with the assessment that Iran incorporates compromised cameras into its operational doctrine, using them both to support missile operations and to conduct ongoing battle damage assessment (BDA).
  • Check Point Research has profiled Silver Dragon, a Chinese-aligned group linked to APT41 that targeted government and enterprise networks across Southeast Asia and Europe. Recent operations used the GearDoor backdoor with SSHcmd and SilverScreen, enabling remote access, covert screen capture, and stealthy control after phishing and server exploitation.

Check Point Harmony Endpoint and Threat Emulation provide protection against these threats

  • Researchers have uncovered Coruna, an iPhone exploit kit used by Chinese scammers and Russia-linked operators to compromise devices through malicious websites. The toolkit used 23 exploits against iOS and deployed malware that stole cryptocurrency, emails, and photos.

Exploits and vulnerabilities in Q4 2025

The fourth quarter of 2025 went down as one of the most intense periods on record for high-profile, critical vulnerability disclosures, hitting popular libraries and mainstream applications. Several of these vulnerabilities were picked up by attackers and exploited in the wild almost immediately.

In this report, we dive into the statistics on published vulnerabilities and exploits, as well as the known vulnerabilities leveraged with popular C2 frameworks throughout Q4 2025.

Statistics on registered vulnerabilities

This section contains statistics on registered vulnerabilities. The data is taken from cve.org.

Let’s take a look at the number of registered CVEs for each month over the last five years, up to and including the end of 2025. As predicted in our last report, Q4 saw a higher number of registered vulnerabilities than the same period in 2024, and the year-end totals also cleared the bar set the previous year.

Total published vulnerabilities by month from 2021 through 2025 (download)

Now, let’s look at the number of new critical vulnerabilities (CVSS > 8.9) for that same period.

Total number of published critical vulnerabilities by month from 2021 to 2025< (download)

The graph shows that the volume of critical vulnerabilities remains quite substantial; however, in the second half of the year, we saw those numbers dip back down to levels seen in 2023. This was due to vulnerability churn: a handful of published security issues were revoked. The widespread adoption of secure development practices and the move toward safer languages also pushed those numbers down, though even that couldn’t stop the overall flood of vulnerabilities.

Exploitation statistics

This section contains statistics on the use of exploits in Q4 2025. The data is based on open sources and our telemetry.

Windows and Linux vulnerability exploitation

In Q4 2025, the most prevalent exploits targeted the exact same vulnerabilities that dominated the threat landscape throughout the rest of the year. These were exploits targeting Microsoft Office products with unpatched security flaws.

Kaspersky solutions detected the most exploits on the Windows platform for the following vulnerabilities:

  • CVE-2018-0802: a remote code execution vulnerability in Equation Editor.
  • CVE-2017-11882: another remote code execution vulnerability, also affecting Equation Editor.
  • CVE-2017-0199: a vulnerability in Microsoft Office and WordPad that allows an attacker to assume control of the system.

The list has remained unchanged for years.

We also see that attackers continue to adapt exploits for directory traversal vulnerabilities (CWE-35) when unpacking archives in WinRAR. They are being heavily leveraged to gain initial access via malicious archives on the Windows operating system:

  • CVE-2023-38831: a vulnerability stemming from the improper handling of objects within an archive.
  • CVE-2025-6218 (formerly ZDI-CAN-27198): a vulnerability that enables an attacker to specify a relative path and extract files into an arbitrary directory. This can lead to arbitrary code execution. We covered this vulnerability in detail in our Q2 2025 report.
  • CVE-2025-8088: a vulnerability we analyzed in our previous report, analogous to CVE-2025-6218. The attackers used NTFS streams to circumvent controls on the directory into which files were being unpacked.

As in the previous quarter, we see a rise in the use of archiver exploits, with fresh vulnerabilities increasingly appearing in attacks.

Below are the exploit detection trends for Windows users over the last two years.

Dynamics of the number of Windows users encountering exploits, Q1 2024 – Q4 2025. The number of users who encountered exploits in Q1 2024 is taken as 100% (download)

The vulnerabilities listed here can be used to gain initial access to a vulnerable system. This highlights the critical importance of timely security updates for all affected software.

On Linux-based devices, the most frequently detected exploits targeted the following vulnerabilities:

  • CVE-2022-0847, also known as Dirty Pipe: a vulnerability that allows privilege escalation and enables attackers to take control of running applications.
  • CVE-2019-13272: a vulnerability caused by improper handling of privilege inheritance, which can be exploited to achieve privilege escalation.
  • CVE-2021-22555: a heap overflow vulnerability in the Netfilter kernel subsystem.
  • CVE-2023-32233: another vulnerability in the Netfilter subsystem that creates a use-after-free condition, allowing for privilege escalation due to the improper handling of network requests.

Dynamics of the number of Linux users encountering exploits, Q1 2024 – Q4 2025. The number of users who encountered exploits in Q1 2024 is taken as 100% (download)

We are seeing a massive surge in Linux-based exploit attempts: in Q4, the number of affected users doubled compared to Q3. Our statistics show that the final quarter of the year accounted for more than half of all Linux exploit attacks recorded for the entire year. This surge is primarily driven by the rapidly growing number of Linux-based consumer devices. This trend naturally attracts the attention of threat actors, making the installation of security patches critically important.

Most common published exploits

The distribution of published exploits by software type in Q4 2025 largely mirrors the patterns observed in the previous quarter. The majority of exploits we investigate through our monitoring of public research, news, and PoCs continue to target vulnerabilities within operating systems.

Distribution of published exploits by platform, Q2 2025 (download)

Distribution of published exploits by platform, Q3 2025 (download)

Distribution of published exploits by platform, Q4 2025 (download)

In Q4 2025, no public exploits for Microsoft Office products emerged; the bulk of the vulnerabilities were issues discovered in system components. When calculating our statistics, we placed these in the OS category.

Vulnerability exploitation in APT attacks

We analyzed which vulnerabilities were utilized in APT attacks during Q4 2025. The following rankings draw on our telemetry, research, and open-source data.

TOP 10 vulnerabilities exploited in APT attacks, Q4 2025 (download)

In Q4 2025, APT attacks most frequently exploited fresh vulnerabilities published within the last six months. We believe that these CVEs will remain favorites among attackers for a long time, as fixing them may require significant structural changes to the vulnerable applications or the user’s system. Often, replacing or updating the affected components requires a significant amount of resources. Consequently, the probability of an attack through such vulnerabilities may persist. Some of these new vulnerabilities are likely to become frequent tools for lateral movement within user infrastructure, as the corresponding security flaws have been discovered in network services that are accessible without authentication. This heavy exploitation of very recently registered vulnerabilities highlights the ability of threat actors to rapidly implement new techniques and adapt old ones for their attacks. Therefore, we strongly recommend applying the security patches provided by vendors.

C2 frameworks

In this section, we will look at the most popular C2 frameworks used by threat actors and analyze the vulnerabilities whose exploits interacted with C2 agents in APT attacks.

The chart below shows the frequency of known C2 framework usage in attacks against users during Q4 2025, according to open sources.

TOP 10 C2 frameworks used by APTs to compromise user systems in Q4 2025 (download)

Despite the significant footprints it can leave when used in its default configuration, Sliver continues to hold the top spot among the most common C2 frameworks in our Q4 2025 analysis. Mythic and Havoc were second and third, respectively. After reviewing open sources and analyzing malicious C2 agent samples that contained exploits, we found that the following vulnerabilities were used in APT attacks involving the C2 frameworks mentioned above:

  • CVE-2025-55182: a React2Shell vulnerability in React Server Components that allows an unauthenticated user to send commands directly to the server and execute them from RAM.
  • CVE-2023-36884: a vulnerability in the Windows Search component that allows the execution of commands on a system, bypassing security mechanisms built into Microsoft Office applications.
  • CVE-2025-53770: a critical insecure deserialization vulnerability in Microsoft SharePoint that allows an unauthenticated user to execute commands on the server.
  • CVE-2020-1472, also known as Zerologon, allows for compromising a vulnerable domain controller and executing commands as a privileged user.
  • CVE-2021-34527, also known as PrintNightmare, exploits flaws in the Windows print spooler subsystem, enabling remote access to a vulnerable OS and high-privilege command execution.
  • CVE-2025-8088 and CVE-2025-6218 are similar directory-traversal vulnerabilities that allow extracting files from an archive to a predefined path without the archiving utility notifying the user.

The set of vulnerabilities described above suggests that attackers have been using them for initial access and early-stage maneuvers in vulnerable systems to create a springboard for deploying a C2 agent. The list of vulnerabilities includes both zero-days and well-known, established security issues.

Notable vulnerabilities

This section highlights the most noteworthy vulnerabilities that were publicly disclosed in Q4 2025 and have a publicly available description.

React2Shell (CVE-2025-55182): a vulnerability in React Server Components

We typically describe vulnerabilities affecting a specific application. CVE-2025-55182 stood out as an exception, as it was discovered in React, a library primarily used for building web applications. This means that exploiting the vulnerability could potentially disrupt a vast number of applications that rely on the library. The vulnerability itself lies in the interaction mechanism between the client and server components, which is built on sending serialized objects. If an attacker sends serialized data containing malicious functionality, they can execute JavaScript commands directly on the server, bypassing all client-side request validation. Technical details about this vulnerability and an example of how Kaspersky solutions detect it can be found in our article.

CVE-2025-54100: command injection during the execution of curl (Invoke-WebRequest)

This vulnerability represents a data-handling flaw that occurs when retrieving information from a remote server: when executing the curl or Invoke-WebRequest command, Windows launches Internet Explorer in the background. This can lead to a cross-site scripting (XSS) attack.

CVE-2025-11001: a vulnerability in 7-Zip

This vulnerability reinforces the trend of exploiting security flaws found in file archivers. The core of CVE-2025-11001 lies in the incorrect handling of symbolic links. An attacker can craft an archive so that when it is extracted into an arbitrary directory, its contents end up in the location pointed to by a symbolic link. The likelihood of exploiting this vulnerability is significantly reduced because utilizing such functionality requires the user opening the archive to possess system administrator privileges.

This vulnerability was associated with a wave of misleading news reports claiming it was being used in real-world attacks against end users. This misconception stemmed from an error in the security bulletin.

RediShell (CVE-2025-49844): a vulnerability in Redis

The year 2025 saw a surge in high-profile vulnerabilities, several of which were significant enough to earn a unique nickname. This was the case with CVE-2025-49844, also known as RediShell, which was unveiled during a hacking competition. This vulnerability is a use-after-free issue related to how the load command functions within Lua interpreter scripts. To execute the attack, an attacker needs to prepare a malicious script and load it into the interpreter.

As with any named vulnerability, RediShell was immediately weaponized by threat actors and spammers, albeit in a somewhat unconventional manner. Because technical details were initially scarce following its disclosure, the internet was flooded with fake PoC exploits and scanners claiming to test for the vulnerability. In the best-case scenario, these tools were non-functional; in the worst, they infected the system. Notably, these fraudulent projects were frequently generated using LLMs. They followed a standardized template and often cross-referenced source code from other identical fake repositories.

CVE-2025-24990: a vulnerability in the ltmdm64.sys driver

Driver vulnerabilities are often discovered in legitimate third-party applications that have been part of the official OS distribution for a long time. Thus, CVE-2025-24990 has existed within code shipped by Microsoft throughout nearly the entire history of Windows. The vulnerable driver has been shipped since at least Windows 7 as a third-party driver for Agere Modem. According to Microsoft, this driver is no longer supported and, following the discovery of the flaw, was removed from the OS distribution entirely.

The vulnerability itself is straightforward: insecure handling of IOCTL codes leading to a null pointer dereference. Successful exploitation can lead to arbitrary command execution or a system crash resulting in a blue screen of death (BSOD) on modern systems.

CVE-2025-59287: a vulnerability in Windows Server Update Services (WSUS)

CVE-2025-59287 represents a textbook case of insecure deserialization. Exploitation is possible without any form of authentication; due to its ease of use, this vulnerability rapidly gained traction among threat actors. Technical details and detection methodologies for our product suite have been covered in our previous advisories.

Conclusion and advice

In Q4 2025, the rate of vulnerability registration has shown no signs of slowing down. Consequently, consistent monitoring and the timely application of security patches have become more critical than ever. To ensure resilient defense, it is vital to regularly assess and remediate known vulnerabilities while implementing technology designed to mitigate the impact of potential exploits.

Continuous monitoring of infrastructure, including the network perimeter, allows for the timely identification of threats and prevents them from escalating. Effective security also demands tracking the current threat landscape and applying preventative measures to minimize risks associated with system flaws. Kaspersky Next serves as a reliable partner in this process, providing real-time identification and detailed mapping of vulnerabilities within the environment.

Securing the workplace remains a top priority. Protecting corporate devices requires the adoption of solutions capable of blocking malware and preventing it from spreading. Beyond basic measures, organizations should implement adaptive systems that allow for the rapid deployment of security updates and the automation of patch management workflows.

The list of vulnerabilities includes both zero-days and well-known, established security issues.

Notable vulnerabilities

This section highlights the most noteworthy vulnerabilities that were publicly disclosed in Q4 2025 and have a publicly available description.

React2Shell (CVE-2025-55182): a vulnerability in React Server Components

We typically describe vulnerabilities affecting a specific application. CVE-2025-55182 stood out as an exception, as it was discovered in React, a library primarily used for building web applications. This means that exploiting the vulnerability could potentially disrupt a vast number of applications that rely on the library. The vulnerability itself lies in the interaction mechanism between the client and server components, which is built on sending serialized objects. If an attacker sends serialized data containing malicious functionality, they can execute JavaScript commands directly on the server, bypassing all client-side request validation. Technical details about this vulnerability and an example of how Kaspersky solutions detect it can be found in our article.

CVE-2025-54100: command injection during the execution of curl (Invoke-WebRequest)

This vulnerability represents a data-handling flaw that occurs when retrieving information from a remote server: when executing the curl or Invoke-WebRequest command, Windows launches Internet Explorer in the background. This can lead to a cross-site scripting (XSS) attack.

CVE-2025-11001: a vulnerability in 7-Zip

This vulnerability reinforces the trend of exploiting security flaws found in file archivers. The core of CVE-2025-11001 lies in the incorrect handling of symbolic links. An attacker can craft an archive so that when it is extracted into an arbitrary directory, its contents end up in the location pointed to by a symbolic link. The likelihood of exploiting this vulnerability is significantly reduced because utilizing such functionality requires the user opening the archive to possess system administrator privileges.

This vulnerability was associated with a wave of misleading news reports claiming it was being used in real-world attacks against end users. This misconception stemmed from an error in the security bulletin.

RediShell (CVE-2025-49844): a vulnerability in Redis

The year 2025 saw a surge in high-profile vulnerabilities, several of which were significant enough to earn a unique nickname. This was the case with CVE-2025-49844, also known as RediShell, which was unveiled during a hacking competition. This vulnerability is a use-after-free issue related to how the load command functions within Lua interpreter scripts. To execute the attack, an attacker needs to prepare a malicious script and load it into the interpreter.

As with any named vulnerability, RediShell was immediately weaponized by threat actors and spammers, albeit in a somewhat unconventional manner. Because technical details were initially scarce following its disclosure, the internet was flooded with fake PoC exploits and scanners claiming to test for the vulnerability. In the best-case scenario, these tools were non-functional; in the worst, they infected the system. Notably, these fraudulent projects were frequently generated using LLMs. They followed a standardized template and often cross-referenced source code from other identical fake repositories.

CVE-2025-24990: a vulnerability in the ltmdm64.sys driver

Driver vulnerabilities are often discovered in legitimate third-party applications that have been part of the official OS distribution for a long time. Thus, CVE-2025-24990 has existed within code shipped by Microsoft throughout nearly the entire history of Windows. The vulnerable driver has been shipped since at least Windows 7 as a third-party driver for Agere Modem. According to Microsoft, this driver is no longer supported and, following the discovery of the flaw, was removed from the OS distribution entirely.

The vulnerability itself is straightforward: insecure handling of IOCTL codes leading to a null pointer dereference. Successful exploitation can lead to arbitrary command execution or a system crash resulting in a blue screen of death (BSOD) on modern systems.

CVE-2025-59287: a vulnerability in Windows Server Update Services (WSUS)

CVE-2025-59287 represents a textbook case of insecure deserialization. Exploitation is possible without any form of authentication; due to its ease of use, this vulnerability rapidly gained traction among threat actors. Technical details and detection methodologies for our product suite have been covered in our previous advisories.

Conclusion and advice

In Q4 2025, the rate of vulnerability registration has shown no signs of slowing down. Consequently, consistent monitoring and the timely application of security patches have become more critical than ever. To ensure resilient defense, it is vital to regularly assess and remediate known vulnerabilities while implementing technology designed to mitigate the impact of potential exploits.

Continuous monitoring of infrastructure, including the network perimeter, allows for the timely identification of threats and prevents them from escalating. Effective security also demands tracking the current threat landscape and applying preventative measures to minimize risks associated with system flaws. Kaspersky Next serves as a reliable partner in this process, providing real-time identification and detailed mapping of vulnerabilities within the environment.

Securing the workplace remains a top priority. Protecting corporate devices requires the adoption of solutions capable of blocking malware and preventing it from spreading. Beyond basic measures, organizations should implement adaptive systems that allow for the rapid deployment of security updates and the automation of patch management workflows.

Mobile malware evolution in 2025

Starting from the third quarter of 2025, we have updated our statistical methodology based on the Kaspersky Security Network. These changes affect all sections of the report except for the installation package statistics, which remain unchanged.

To illustrate trends between reporting periods, we have recalculated the previous year’s data; consequently, these figures may differ significantly from previously published numbers. All subsequent reports will be generated using this new methodology, ensuring accurate data comparisons with the findings presented in this article.

Kaspersky Security Network (KSN) is a global network for analyzing anonymized threat intelligence, voluntarily shared by Kaspersky users. The statistics in this report are based on KSN data unless explicitly stated otherwise.

The year in figures

According to Kaspersky Security Network, in 2025:

  • Over 14 million attacks involving malware, adware or unwanted mobile software were blocked.
  • Adware remained the most prevalent mobile threat, accounting for 62% of all detections.
  • Over 815 thousand malicious installation packages were detected, including 255 thousand mobile banking Trojans.

The year’s highlights

In 2025, cybercriminals launched an average of approximately 1.17 million attacks per month against mobile devices using malicious, advertising, or unwanted software. In total, Kaspersky solutions blocked 14,059,465 attacks throughout the year.

Beyond the malware mentioned in previous quarterly reports, 2025 saw the discovery of several other notable Trojans. Among these, in Q4 we uncovered the Keenadu preinstalled backdoor. This malware is integrated into device firmware during the manufacturing stage. The malicious code is injected into libandroid_runtime.so – a core library for the Android Java runtime environment – allowing a copy of the backdoor to enter the address space of every app running on the device. Depending on the specific app, the malware can then perform actions such as inflating ad views, displaying banners on behalf of other apps, or hijacking search queries. The functionality of Keenadu is virtually unlimited, as its malicious modules are downloaded dynamically and can be updated remotely.

Cybersecurity researchers also identified the Kimwolf IoT botnet, which specifically targets Android TV boxes. Infected devices are capable of launching DDoS attacks, operating as reverse proxies, and executing malicious commands via a reverse shell. Subsequent analysis revealed that Kimwolf’s reverse proxy functionality was being leveraged by proxy providers to use compromised home devices as residential proxies.

Another notable discovery in 2025 was the LunaSpy Trojan.

TOP ATTACKS AND BREACHES

  • France’s Ministry of Economy has disclosed a data breach resulted from an unauthorized access to the national bank account registry FICOBA, impacting information tied to 1.2 million accounts. Exposed data includes names, addresses, account identifiers and, in some cases, tax-related identifiers. Officials said the intrusion involved compromised government credentials.
  • Japanese tech giant Advantest Corporation was hit by a ransomware attack that resulted in the deployment of ransomware within portions of its network following unauthorized access by a third party on February 15. The incident may have impacted certain internal systems, and the potential compromise of customer or employee data remains unclear.
  • University of Mississippi Medical Center, an academic healthcare system in Mississippi, has suffered a ransomware attack that forced closures across its clinic network and disrupted access to electronic medical records. The organization canceled elective procedures and shifted to manual processes. Systems were taken offline and no ransomware group claimed responsibility.
  • Ukraine’s central bank, the National Bank of Ukraine (NBU), has faced a supply-chain incident affecting a contractor that runs its collectible coin online store. Exposed information includes customer registration data, such as names, emails, phone numbers, and delivery addresses. The bank indicated that payment information was not affected.

AI THREATS

  • Check Point Research unveiled a technique that repurposes AI assistants like Grok and Microsoft Copilot as covert C2 proxies by abusing web-browsing URL fetch features without authentication. Malware exfiltrates host data via query parameters and retrieves commands from AI-generated summaries through hidden WebView2, bypassing inspection of AI traffic.
