Security Shield

Security Shield

This plugin is active by default and protects against:

Dangerous command blocking

Tool calls containing destructive patterns are blocked before execution:

• rm -rf, mkfs, dd of=/dev/, shred — file/disk destruction
• curl ... | bash, base64 -d | sh — remote code execution
• shutdown, reboot, kill -9 -1 — system disruption
• Reverse shell patterns (bash -i >&, /dev/tcp/)
• Crypto mining (xmrig, stratum+tcp)
• Access to ~/.ssh/, ~/.aws/credentials, .env files

Secret leak detection

Tool output is scanned for known credential patterns:

• OpenAI (sk-proj-*), Anthropic (sk-ant-api*), Google (AIza*)
• GitHub tokens (ghp_*, github_pat_*)
• AWS keys (AKIA*), Stripe (sk_live_*), Slack (xox*-*)
• PEM private keys, Bearer tokens, credentials in URLs

Detected secrets are replaced with [REDACTED:rule-id] before reaching the LLM.

Audit log

All tool calls are logged to ~/.openclaw/security-audit.jsonl with:

• Timestamp, tool name, parameters (truncated to 500 chars)
• Whether the call was blocked and why
• Security findings (rule matches)
• Execution duration and errors

Configuration

In ~/.openclaw/openclaw.json under plugins.security-shield:

• enforcement: "block" (default), "warn", or "off"
• auditLog: true (default) or false
• leakDetection: true (default) or false
