The OpenClaw ecosystem has had a turbulent few months on the security front. In late January 2026, researchers discovered that roughly 12 percent of all ClawHub skills were malicious — 341 packages across multiple campaigns. By mid-February the number swelled to 824 malicious skills spanning 12 publisher accounts. The primary operation, dubbed ClawHavoc, distributed the Atomic Stealer (AMOS) macOS infostealer, targeting crypto wallets, SSH credentials, and browser-stored passwords. A separate wave pushed Vidar and GhostSocks malware through seemingly innocent automation skills.
OpenClaw responded with a VirusTotal partnership that now scans every new ClawHub upload, but that only catches threats at publish time. What about skills already installed on your machine, or novel attack vectors that emerge between scans? That gap is exactly what openclaw-security-monitor was built to fill.
What It Does
openclaw-security-monitor is an open-source OpenClaw skill created by developer adibirzu that runs proactive, continuous security checks against your live OpenClaw deployment. Rather than waiting for ClawHub’s server-side VirusTotal scan to flag a problem, this skill monitors your local installation from the inside — inspecting installed skills, watching for suspicious behavior patterns, and alerting you the moment something looks wrong.
Think of it as an intrusion detection system purpose-built for the OpenClaw runtime. It understands the specific threat landscape that OpenClaw deployments face and checks for attack patterns that a generic antivirus would miss entirely.
The Threat Coverage
The skill’s detection library is impressively comprehensive. It covers the major named campaigns and vulnerability classes that have hit the OpenClaw ecosystem so far:
Known malware campaigns: ClawHavoc (the 824-skill AMOS stealer campaign), Vidar infostealer variants, and GhostSocks proxy malware — all of which were distributed through ClawHub between January and February 2026.
Critical CVEs: The tool tracks over 60 CVEs, including CVE-2026-25253, the WebSocket hijacking vulnerability that allowed full remote code execution on any OpenClaw instance through a single crafted link — even instances bound to localhost.
Supply chain attacks: Detection for workspace plugin auto-loading exploits, shared-auth scope escalation, approval replay and integrity bypasses, TAR path traversal, and SHA-1 cache poisoning — the kinds of subtle attacks that slip through file-level malware scanning.
Runtime manipulation: Memory poisoning, log poisoning, MCP tool poisoning, browser relay hijacking, and even SANDWORM-style worm propagation between connected agents. These are the threats that only matter once a skill is already running inside your environment.
Who Needs This
If you are running OpenClaw with any ClawHub skills installed — and especially if your agent has access to sensitive resources like email, cloud credentials, smart home devices, or financial accounts — this skill fills a real gap in the security stack. The VirusTotal partnership catches known-bad skills at upload time, but it does not help with zero-day exploits, skills that were installed before scanning was introduced, or attack patterns that operate at the runtime level rather than the file level.
Self-hosters running OpenClaw on a home server or VPS should pay particular attention. Security researchers found over 30,000 publicly exposed OpenClaw instances in early 2026, many with default configurations that grant broad permissions. The security monitor skill adds a layer of defense that is especially valuable when your deployment is internet-facing.
Installation
Install it directly from ClawHub:
npx clawhub@latest install openclaw-security-monitorAlternatively, you can clone the repository directly from GitHub if you want to inspect every line of code before granting it access to your system — which, given the subject matter, is entirely reasonable.
A Note on Trust
There is an inherent irony in installing a security skill from a third-party developer to protect yourself from malicious third-party skills. The skill requests broad access to inspect your OpenClaw environment, which means you need to trust its author and its code. Before installing, review the SKILL.md and the source repository carefully. Check the commit history, look at open issues, and verify that the permission requests make sense for what the tool claims to do. This is good practice for any security-sensitive skill, and doubly so for one that is itself a security tool.
The Bigger Picture
The emergence of dedicated security monitoring skills like this one signals a maturing ecosystem. When ClawHub crossed 13,000 skills in February 2026, a Snyk audit flagged 13.4 percent of them for critical issues — a number that makes clear the scale of the supply chain challenge. OpenClaw’s VirusTotal integration, the community’s security audit tools, and now proactive runtime monitors like openclaw-security-monitor represent different layers of a defense-in-depth approach that the ecosystem badly needs.
No single tool solves the problem. But if you are running OpenClaw in any environment where security matters — and it should matter everywhere — adding a runtime security monitor to your skill stack is a practical step you can take today.
