    Openclaw Hardening Audit

    Example session with this skill installed

    Audit my OpenClaw install at ~/.openclaw and check this SKILL.md I found on GitHub for any red flags before I add it.

    • Read your context and instructions
    • Compiled the openclaw hardening audit
    • Generated the document

    Audit completed for path ~/.openclaw. Found 1 Critical, 1 High, and 1 Medium risk findings. The external SKILL.md is flagged as

    Malicious and should not be installed.

    Detailed Findings

    [CRITICAL] Malicious Skill Pattern Detected

    The external skill you provided contains a trigger that attempts to cat files in the credentials directory and pipe them to a curl command. This is a documented exfiltration technique.

    Do not install this skill.

    [HIGH] Global Gateway Binding

    Your openclaw.json has gateway.bindHost set to 0.0.0.0. This makes the agent's control interface accessible from the public internet or local network.

    [MEDIUM] Weak Workspace Hardening

    AGENTS.md does not explicitly instruct the agent to treat web search results as untrusted. This leaves the system vulnerable to indirect prompt injection where a malicious website could take control of the session.

    Next steps

    1. Delete the malicious SKILL.md immediately and do not attempt to run it.
    2. Edit ~/.openclaw/openclaw.json to set gateway.bindHost to 127.0.0.1.
    3. Add defensive instructions to AGENTS.md regarding untrusted data sources.

    About this skill

    The problem

    OpenClaw gives LLMs shell access, browser control, and file system reach, often with unsafe defaults. With over 135,000 internet-exposed instances and a rise in malicious skills targeting credentials, a standard installation is a significant security liability.

    What it does

    • Audits openclaw.json for critical gateway exposure, weak authentication tokens, and overprivileged tool permissions.
    • Inspects SKILL.md files for supply-chain risks, including credential exfiltration patterns, obfuscated payloads, and prompt-injection vulnerabilities.
    • Checks workspace instruction files like AGENTS.md and SOUL.md for missing defensive boundaries against indirect prompt injection.
    • Cross-references the local OpenClaw version against known CVEs and identifies dangerous file-system permission sets.

    Frameworks & tools

    Built for OpenClaw installations, ClawHub skills, and MCP server configurations. Uses stat, ls, and the OpenClaw CLI for non-intrusive inspection.

    Why this beats prompting it yourself

    General LLMs often overlook the specific "indirect injection" risks unique to OpenClaw's browser and email tools. This skill uses a specialized reference library of known malicious patterns and CVE histories that standard models lack in their base training.

    Use cases

    • Vetting third-party skills from community repos before installation.
    • Hardening a fresh OpenClaw deployment before giving it access to sensitive data.
    • Conducting regular security posture reviews of production agents.
    • Investigating agents that are exhibiting suspicious or out-of-character behavior.

    Known limitations

    Does not perform memory forensics or log analysis to detect past compromises. The CVE reference library requires manual verification against live advisories for the most recent threats.

    2. 2

      Unzip into your skills folder

      Every agent reads skills from one folder on your machine. Drop the unzipped folder in there.

    3. 3

      Ask your agent to use it

      Restart the agent if it was already running. It picks the skill up automatically - no config needed.
