From Automation to Infection: How OpenClaw AI Agent Skills Are Being Weaponized

2 February 2026 at 21:52

The fastest-growing personal AI agent ecosystem just became a new delivery channel for malware. Over the last few days, VirusTotal has detected hundreds of OpenClaw skills that are actively malicious. What started as an ecosystem for extending AI agents is rapidly becoming a new supply-chain attack surface, where attackers distribute droppers, backdoors, infostealers and remote access tools disguised as helpful automation.

What is OpenClaw (formerly Clawdbot / Moltbot)?

Unless you’ve been completely disconnected from the internet lately, you’ve probably heard about the viral success of OpenClaw and its small naming soap opera. What started as Clawdbot, briefly became Moltbot, and finally settled on OpenClaw, after a trademark request made the original name off-limits.

At its core, OpenClaw is a self-hosted AI agent that runs on your own machine and can execute real actions on your behalf: shell commands, file operations, network requests. Which is exactly why it’s powerful, and also why, unless you actively sandbox it, the security blast radius is basically your entire system.

Skills: powerful by design, dangerous by default

OpenClaw skills are essentially small packages that extend what the agent can do. Each skill is built around a SKILL.md file (with some metadata and instructions) and may include scripts or extra resources. Skills can be loaded locally, but most users discover and install them from ClawHub, the public marketplace for OpenClaw extensions.

This is what makes the ecosystem so powerful: instead of hardcoding everything into the agent, you just add skills and suddenly it can use new tools, APIs, and workflows. The agent reads the skill documentation on demand and follows its instructions.

The problem is that skills are also third-party code, running in an environment with real system access. And many of them come with β€œsetup” steps users are trained to trust: paste this into your terminal, download this binary and run it, export these environment variables. From an attacker’s perspective, it’s a perfect social-engineering layer.

So yes, skills are a gift for productivity and, unsurprisingly, a gift for malware authors too. Same mechanism, very different intentions.

What we added: OpenClaw Skill support in VirusTotal Code Insight

To help detect this emerging abuse pattern, we’ve added native support in VirusTotal Code Insight for OpenClaw skill packages, including skills distributed as ZIP files. Under the hood, we use Gemini 3 Flash to perform a fast security-focused analysis of the entire skill, starting from SKILL.md and including any referenced scripts or resources.

The goal is not to understand what the skill claims to do, but to summarize what it actually does from a security perspective: whether it downloads and executes external code, accesses sensitive data, performs network operations, or embeds instructions that could coerce the agent into unsafe behavior. In practice, this gives analysts a concise, security-first description of the real behavior of a skill, making it much easier to spot malicious patterns hidden behind β€œhelpful” functionality.

What we’re seeing in the wild

At the time of writing, VirusTotal Code Insight has already analyzed more than 3,016 OpenClaw skills, and hundreds of them show malicious characteristics.

Not all of these cases are the same. On one side, we are seeing many skills flagged as dangerous because they contain poor security practices or outright vulnerabilities: insecure use of APIs, unsafe command execution, hardcoded secrets, excessive permissions, or sloppy handling of user input. This is increasingly common in the era of vibe coding, where code is generated quickly, often without a real security model, and published straight into production.

But more worrying is the second group: skills that are clearly and intentionally malicious. These are presented as legitimate tools, but their real purpose is to perform actions such as sensitive data exfiltration, remote control via backdoors, or direct malware installation on the host system.

Case study: hightower6eu, a malware publisher in plain sight

One of the most illustrative cases we’ve observed is the ClawHub user "hightower6eu", who is highly active publishing skills that appear legitimate but are consistently used to deliver malware



At the time of writing, VirusTotal Code Insight has already analyzed 314 skills associated with this single user, and the number is still growing, all of them identified as malicious. The skills cover a wide range of apparently harmless use cases (crypto analytics, finance tracking, social media analysis, auto-updaters, etc) but they all follow a similar pattern: users are instructed to download and execute external code from untrusted sources as part of the "setup" process.



To make this more tangible, the screenshot below shows how VirusTotal Code Insight analyzes one of the skills published by hightower6eu, in this case a seemingly harmless skill called "Yahoo Finance".

On the surface, the file looks clean: no antivirus engines flag it as malicious, and the ZIP itself contains almost no real code. This is exactly why traditional detection fails.

VT Code Insight, however, looks at the actual behavior described in the skill. In this case, it identifies that the skill instructs users to download and execute external code from untrusted sources as a mandatory prerequisite, both on Windows and macOS. From a security perspective, that’s a textbook malware delivery pattern: the skill acts as a social engineering wrapper whose only real purpose is to push remote execution. In other words, nothing in the file is technically "malware" by itself. The malware is the workflow. And that’s precisely the kind of abuse pattern Code Insight is designed to surface.


79e8f3f7a6113773cdbced2c7329e6dbb2d0b8b3bf5a18c6c97cb096652bc1f2

If you actually read the SKILL.md, the real behavior becomes obvious. For Windows users, the skill instructs them to download a ZIP file from an external GitHub account, protected with the password 'openclaw', extract it, and run the contained executable: openclaw-agent.exe.


When submitted to VirusTotal, this executable is detected as malicious by multiple security vendors, with classifications consistent with packed trojans.

17703b3d5e8e1fe69d6a6c78a240d8c84b32465fe62bed5610fb29335fe42283

When the system is macOS, the skill doesn't provide a binary directly. Instead, it points the user to a shell script hosted on glot.io, which is obfuscated using Base64:


Once the Base64 payload is decoded, the real behavior becomes visible: the script simply downloads and executes another file from a remote server over plain HTTP:


The final stage is the file x5ki60w1ih838sp7, a Mach-O executable. When submitted to VirusTotal, this binary is detected as malicious by 16 security engines, with classifications consistent with stealer trojans and generic malware families:

1e6d4b0538558429422b71d1f4d724c8ce31be92d299df33a8339e32316e2298

When the file is analyzed by multiple automated reversing tools and Gemini 3 Pro, the results are consistent: the binary is identified as a trojan infostealer, and more specifically as a variant of Atomic Stealer (AMOS).


This family of malware is well known in the macOS ecosystem. It is designed to run stealthily in the background and systematically harvest sensitive user data, including system and application passwords, browser cookies and stored credentials, and cryptocurrency wallets and related artifacts.

What OpenClaw users (and platforms) should do right now

OpenClaw itself provides reasonable security building blocks, but they only help if people actually use them:

  • Treat skill folders as trusted-code boundaries and strictly control who can modify them.
  • Prefer sandboxed executions and keep agents away from sensitive credentials and personal data.
  • Be extremely skeptical of any skill that requires pasting commands into a shell or running downloaded binaries.
  • If you operate a registry or marketplace, add publish-time scanning and flag skills that include remote execution, obfuscated scripts, or instructions designed to bypass user oversight.

And if you’re installing community skills: scan them first. For personal AI agents, the supply chain is not a detail, it’s the whole product.

Finally, we want to give full credit to Peter Steinberger, the creator of OpenClaw, for the success, traction, and energy around the project. From our side, we’d love to collaborate and explore ways to integrate VirusTotal directly into the OpenClaw publishing and review workflow, so that developers and users can benefit from security analysis without getting in the way of innovation.

HowΒ Manifest v3Β forced us to rethinkΒ Browser Guard, and whyΒ that’sΒ a good thingΒ 

2 February 2026 at 19:11

As a Browser Guard user, you might not have noticed much difference lately. Browser Guard still blocks scams and phishing attempts just like always, and, in many cases, even better.

But behind the scenes, almost everything changed. The rules that govern how browser extensions work went through a major overhaul, and we had to completely rebuild how Browser Guard protects you.

First,Β whatΒ is Manifest v3Β (andΒ v2)?Β 

Browser extensions include a configuration file called a β€œmanifest”. Think of it as an instruction manual that tells your browser what an extension can do and how it’s allowed to do it.

Manifest v3 is the latest version of that system, and it’s now the only option allowed in major browsers like Chrome and Edge.

In Manifest v2, Browser Guard could use highly customized logic to analyze and block suspicious activity as it happened, protecting you as you browsed the web.

With Manifest v3, that flexibility is mostly gone. Extensions can no longer run deeply complex, custom logic in the same way. Instead, we can only pass static rule lists to the browser, called Declarative Net Request (DNR) rules.

But those DNR rules come with strict constraints.

Rule sets are size-limited by the browser to save space. Because rules are stored as raw JSON files, developers can’t use other data types to make them smaller. And updating those DNR rules can only be done by updating the extension entirely.

This is less of a problem on Chrome, which allows developers to push updates quickly, but other browsers don’t currently support this fast-track process. Dynamic rule updates exist, but they’re limited, and nowhere near large enough to hold the full set of rules.

In short, we couldn’t simply port Browser Guard from Manifest v2 to v3. The old approach wouldn’t keep our users protected.

AΒ noteΒ about Firefox and BraveΒ 

Firefox and Brave chose a different path and continue to support the more flexible Manifest v2 method of blocking requests.

However, since Brave doesn’t have its own extension store, users can only install extensions they already had before Google removed Manifest v2 extensions from the Chrome Web Store. Though Brave also has strong out-of-the-box ad protection.

For Browser Guard users on Firefox, rest assured the same great blocking techniques will continue to work.

How Browser GuardΒ still protectsΒ youΒ 

Given all of this, we had to get creative.

Many ad blockers already support pattern-based matching to stop ads and trackers. We asked a different question: what if we could use similar techniques to catch scam and phishing attempts before we know the specific URL is malicious?

Better yet, what if we did it without relying on the new DNR APIs?

So, we built a new pattern-matching system focused specifically on scam and phishing behavior, supporting:

  • Full regex-based URL matching
  • Full XPath and querySelector support
  • Matching against any content on the page
  • Favicon spoof detection

For example, if a site is hosted on Amazon S3, contains a password-input field, and uses a homoglyph in the URL to trick users into thinking they were logging into Facebook, Browser Guard can detect that combinationβ€”even if we’ve never seen the URL before.

Fake Facebook login screen

Why this matters more nowΒ 

With AI,Β attackersΒ canΒ createΒ near-perfect duplicates of websitesΒ easier than ever.Β And did you spot the homoglyph in the URL? Nope, neither did I!Β Β 

That’sΒ why we designed this system so weΒ canΒ updateΒ itsΒ rulesΒ every 30 minutes,Β instead of waiting for full extension updates.Β Β 

ButΒ I still seeΒ staticΒ blockingΒ rulesΒ in Browser GuardΒ 

That’sΒ trueβ€”for now.Β Β 

We’ve found a temporary workaround that lets us support all the rules that we had before. However, we had to remove some of the more advanced logic that used to sit on top of them.

For example, we can’t use these large datasets to block subframe requests, only main frame requests. Nor can we stack multiple logic layers together; blocking is limited to simple matches (regex, domains and URLs).

ThoseΒ limits are a big reasonΒ we’reΒ investingΒ moreΒ heavily inΒ pattern-basedΒ andΒ heuristicΒ protection.Β 

PureΒ heuristicsΒ 

From day one, Browser Guard has used heuristics (behavior) to detect scams and phishing, monitoring behavior on the page to match suspicious activity.

For example, some scam pages deliberately break your browser’s back button by abusing window.replaceState, then trick you into calling that scammer’s β€œcomputer helpline.” Others try to convince you to run malicious commands on your computer.

Browser Guard canΒ detectΒ theseΒ behaviorsΒ andΒ warnΒ youΒ before you fall for them.Β 

What’sΒ next?Β 

Did someone say AI?Β Β 

You’veΒ probably seenΒ Scam GuardΒ inΒ other Malwarebytes products.Β We’re currently working on a version tailored specifically for Browser Guard. More soon!

Final thoughtsΒ 

While Manifest v3 introduced meaningful improvements to browser security, it also created real challenges for security tools like Browser Guard.

Rather than scaling back, the Browser Guard team rebuilt our approach from the ground up, focusing on behavior, patterns, and faster response times. The result is protection that’s different under the hood, but just as committed to keeping you safe online.

2nd February – Threat Intelligence Report

By: lorenf
2 February 2026 at 14:35

For the latest discoveries in cyber research for the week of 2nd February, please download our Threat Intelligence Bulletin.

TOP ATTACKS AND BREACHES

  • MicroWorld Technologies, maker of eScan antivirus, has suffered a supply-chain compromise. Malicious updates were pushed via the legitimate eScan updater, delivering multi-stage malware that establishes persistence, enables remote access, and blocks automatic updates. In response, eScan shut down its global update service for more than eight hours.
  • Crunchbase, a private company intelligence platform, has confirmed a data breach of over 2 million records claimed by ShinyHunters threat group after a ransom demand was refused. The published files were stolen from its corporate network and include customer names, contact details, partner contracts and other internal documents. Crunchbase said that their operations were not disrupted.
  • Qilin ransomware group has leaked an alleged database belonging to Tulsa International Airport in Oklahoma. The database include financial records, internal emails, and employee identification data. The airport authority has not yet confirmed compromise, and operations reportedly continue.

Check Point Threat Emulation provides protection against this threat (Ransomware.Wins.Qilin.ta.*; Ransomware.Wins.Qilin)

  • WorldLeaks extortion group has claimed responsibility for a data breach on the sportswear giant Nike. The threat group allegedly exposed samples totaling 1.4 terabytes of internal data including documents and archives related to the company’s supply chain and manufacturing operations.

AI THREATS

  • Clawdbot, an open source AI agent gateway, has more than 900 publicly exposed and often unauthenticated instances due to localhost auto approval behind reverse proxies. It enables credential theft, access to chat histories, and remote code execution.
  • Researchers uncovered RedKitten, a 2026 campaign with LLM-assisted development indicators targeting Iranian activists and NGOs. The campaign uses password-protected Excel lures to deliver SloppyMIO, a C# implant that uses Telegram for C2 and GitHub/Google Drive for payloads, with steganographic configuration, AppDomain Manager injection, and scheduled task persistence.
  • Researchers identified 16 malicious Chrome extensions for ChatGPT that exfiltrate authorization details and session tokens. The extensions inject scripts into the ChatGPT web application to monitor outbound requests, allowing attackers to hijack sessions and access chat histories.
  • Researchers analyzed publicly accessible open-source LLM deployments via Ollama and revealed many with disabled guardrails and exposed system prompts, enabling spam, phishing, disinformation, and other abuse.

VULNERABILITIES AND PATCHES

  • A critical path traversal vulnerability (CVE-2025-8088) in WinRAR is actively exploited by government backed threat actors linked to Russia and China as well as financially motivated threat actors. Weaponized phishing forces WinRAR to write malware into the Windows Startup folder, enabling automatic execution for ransomware and credential theft. A patch is available on WinRAR 7.13.

Check Point IPS provides protection against this threat (RARLAB WinRAR Directory Traversal (CVE-2025-8088))

  • SmarterTools addressed two critical SmarterMail flaws, including CVE-2026-24423 enabling remote code execution and CVE-2026-23760 allowing unauthenticated admin account takeover. The second flaw is actively exploited, and over 6,000 exposed SmarterMail servers are reportedly vulnerable.

Check Point IPS provides protection against this threat (SmarterTools SmarterMail Remote Code Execution (CVE-2026-24423); SmarterTools SmarterMail Authentication Bypass (CVE-2026-23760))

  • Fortinet has fixed CVE-2026-24858, an authentication bypass in FortiCloud single sign on which allowed unauthorized access and admin creation on downstream devices. The flaw carries CVSS 9.4 and is actively exploited via FortiCloud SSO.

THREAT INTELLIGENCE REPORTS

  • Check Point Research has published the 2026 Cyber Security Report, highlighting AI as a force multiplier across attacks, fragmentation in ransomware with data only extortion, and multi-channel social engineering attacks. It maps threat activity to geopolitics and identity driven paths, quantifies risky AI usage, and provides sector and regional breakouts.
  • Polish CERT detailed coordinated destructive attacks on Polish energy and manufacturing sectors, attributed to Static Tundra, using FortiGate SSL VPN access. The attackers conducted reconnaissance, firmware damage, lateral movement, and deployed DynoWiper and LazyWiper that corrupt files.
  • Researchers have uncovered renewed Matanbuchus downloader campaigns using Microsoft Installer files disguised as legitimate installers, with frequent component changes to evade antivirus and machine learning detection. In many cases, the loader is used for further ransomware deployment.

Check Point Harmony Endpoint and Threat Emulation provide protection against this threat (Trojan-Downloader.Wins.Matanbuchus.ta.*; Trojan-Downloader.Wins.Matanbuchus; Trojan-Downloader.Win.Matanbuchus)

  • Researchers have identified PyRAT, a Python based cross platform RAT for Windows and Linux, using unencrypted HTTP POST C2, fingerprinting victims, and file and screenshot exfiltration. Persistence uses a deceptive autostart on Linux and a user Run key on Windows, with semi persistent identifiers.
  • Researchers have found an Android campaign distributing a RAT via fake security alerts installing TrustBastion, which retrieves a second-stage payload from Hugging Face. The malware abuses Accessibility Services, deploys credential-stealing overlays, and uses server-side polymorphism to regenerate payloads every 15 minutes.

How fake party invitations are being used to install remote access tools

2 February 2026 at 11:18

β€œYou’re invited!” 

It soundsΒ friendly,Β familiarΒ and quiteΒ harmless.Β But in aΒ scamΒ we recentlyΒ spotted, thatΒ simpleΒ phrase is beingΒ usedΒ to trick victims into installing a full remote access tool on theirΒ WindowsΒ computersβ€”giving attackers complete control of the system.Β 

What appears to be aΒ casual party or event invitationΒ leads toΒ the silent installation ofΒ ScreenConnect, a legitimate remoteΒ supportΒ toolΒ quietly installedΒ in the background and abused byΒ attackers.Β 

Here’s how theΒ scamΒ works, whyΒ it’sΒ effective, andΒ how to protect yourself.Β 

TheΒ email: AΒ partyΒ invitationΒ 

Victims receive an email framed as a personal invitationβ€”often written to look like it came from a friend or acquaintance. The message is deliberately informal and social, lowering suspicion and encouraging quick action.Β 

In the screenshot below, the email arrived from a friend whose email account had been hacked, but it could just as easily come from a sender you don’t know.

So far,Β we’veΒ only seenΒ thisΒ campaignΒ targetingΒ peopleΒ in theΒ UK,Β butΒ there’s nothingΒ stoppingΒ it from expandingΒ elsewhere.Β 

Clicking the link in the email leadsΒ to a polishedΒ invitationΒ page hosted on an attacker-controlled domain.Β 

Party invitation email from a contact

TheΒ invite: TheΒ landing pageΒ thatΒ leads to an installerΒ 

The landing page leans heavily into theΒ partyΒ theme,Β but instead of showing event details, the pageΒ nudgesΒ the user toward opening a file. None of them look dangerous on their own, but together theyΒ keep the user focused on theΒ β€œinvitation” file:Β 

  • A boldΒ β€œYou’re Invited!” headlineΒ 
  • The suggestion that aΒ friend had sent the invitationΒ 
  • AΒ messageΒ sayingΒ the invitation is best viewed on aΒ Windows laptop or desktop
  • A countdownΒ suggestingΒ yourΒ invitation is already β€œdownloading” 
  • A message implying urgency and social proof (β€œI opened mine and it was so easy!”)Β 

Within seconds, the browser is redirected to downloadΒ RSVPPartyInvitationCard.msiΒ 

The page even triggers the download automatically to keep the victim moving forward without stopping to think.Β 

This MSI fileΒ isn’tΒ an invitation.Β It’sΒ an installer.Β 

The landing page

TheΒ guest: What the MSIΒ actuallyΒ doesΒ 

When theΒ user opens theΒ MSI file, it launchesΒ msiexec.exeΒ andΒ silentlyΒ installsΒ ScreenConnectΒ Client, a legitimate remote access tool often used by IT support teams.Β Β 

There’sΒ noΒ invitation, RSVP form, or calendar entry.Β 

What happens instead:Β 

  • ScreenConnectΒ binaries areΒ installedΒ underΒ C:\Program Files (x86)\ScreenConnectΒ Client\Β 
  • AΒ persistent Windows serviceΒ is createdΒ (for example,Β ScreenConnectΒ ClientΒ 18d1648b87bb3023)Β 
  • ScreenConnectΒ installsΒ multiple .NET-based componentsΒ 
  • There is no clear user-facingΒ indicationΒ that a remote access tool is being installedΒ 

From the victim’s perspective,Β very littleΒ seems to happen. But at this point, the attackerΒ can now remotely accessΒ theirΒ computer.Β 

TheΒ after-party: RemoteΒ accessΒ isΒ establishedΒ 

Once installed, the ScreenConnect client initiates encrypted outbound connections to ScreenConnect’s relay servers, including a uniquely assigned instance domain.

That connectionΒ givesΒ the attacker theΒ same level of access as a remote ITΒ technician, including theΒ ability to:Β 

  • SeeΒ the victim’s screen in real time
  • ControlΒ theΒ mouse and keyboardΒ 
  • Upload or downloadΒ filesΒ 
  • KeepΒ accessΒ even after the computer is restartedΒ 

BecauseΒ ScreenConnectΒ is legitimate softwareΒ commonlyΒ usedΒ for remote support,Β its presenceΒ isn’tΒ always obvious. On a personal computer, the first signs are often behavioral, such as unexplained cursor movement, windows opening on their own, or a ScreenConnect process the user doesn’t remember installing.Β 

WhyΒ thisΒ scamΒ worksΒ 

This campaign is effective because it targetsΒ normal, predictable human behavior. From a behavioral security standpoint, it exploitsΒ our naturalΒ curiosityΒ andΒ appears to beΒ a lowΒ risk.Β 

Most peopleΒ don’tΒ think of invitations as dangerous. Opening one feels passive,Β like glancing at a flyer or checking a message, not installing software.Β 

Even security-aware users are trained to watch out for warnings and pressure. A friendly β€œyou’re invited” messageΒ doesn’tΒ trigger those alarms.Β 

By the time something feels off, the software is already installed.Β 

Signs your computer may be affectedΒ 

Watch for:Β 

  • A download or executed file namedΒ RSVPPartyInvitationCard.msiΒ 
  • AnΒ unexpected installation ofΒ ScreenConnectΒ ClientΒ 
  • AΒ Windows serviceΒ namedΒ ScreenConnectΒ ClientΒ with random charactersΒ Β 
  • Your computer makes outbound HTTPS connections toΒ ScreenConnectΒ relay domainsΒ 
  • Your system resolvesΒ the invitation-hosting domain used in this campaign,Β xnyr[.]digitalΒ 

How to stay safeΒ Β 

This campaign is a reminder that modern attacks oftenΒ don’tΒ break inβ€”they’reΒ invited in.Β Remote access tools give attackers deep control over a system. Acting quickly can limitΒ the damage.Β Β 

For individualsΒ 

If you receive an email like this:Β 

  • Be suspicious of invitations that ask you to download or open softwareΒ 
  • Never run MSI files from unsolicited emailsΒ 
  • Verify invitations through another channel before opening anythingΒ 

If you already clicked or ran the file:Β Β 

  • Disconnect from the internetΒ immediatelyΒ 
  • Check forΒ ScreenConnectΒ and uninstall it if presentΒ 
  • Run a full security scanΒ 
  • Change important passwords from a clean, unaffected deviceΒ 

ForΒ organisationsΒ (especially in the UK)Β 

  • Alert onΒ unauthorizedΒ ScreenConnectΒ installations
  • Restrict MSI execution whereΒ feasibleΒ 
  • Treat β€œremote support tools” as high-risk software
  • Educate users:Β invitationsΒ don’tΒ come as installersΒ 

This scam works by installing a legitimate remote access tool without clear user intent. That’s exactly the gap Malwarebytes is designed to catch.

Malwarebytes now detects newly installed remote access tools and alerts you when one appears on your system. You’re then given a choice: confirm that the tool is expected and trusted, or remove it if it isn’t.
