OpenClaw Security: Runtime Protection for AI Assistants
Native interceptor-based security for OpenClaw agents
OpenClaw is the most popular open-source AI assistant with 50+ integrations, shell access, file I/O, and browser automation. But every tool call is an attack surface. Over 1,000 malicious skills have been discovered on ClawHub. Rune's plugin hooks into OpenClaw's native interceptor pipeline to scan every tool call and message before execution.

Why OpenClaw Agents Need Runtime Security
OpenClaw agents run locally with access to your file system, shell, email, calendar, and messaging apps. A single malicious skill or prompt injection can exfiltrate SSH keys, send unauthorized emails, or execute destructive commands. The January 2026 audit found 512 vulnerabilities including 8 critical ones, and CVE-2026-25253 enables remote code execution.
Top Threats to OpenClaw Agents
Over 1,000 malicious skills discovered on ClawHub deploying info-stealers and backdoors. The ClawHavoc campaign planted 1,184 coordinated malicious skills. Skills can instruct agents to read SSH keys, forward emails, or exfiltrate API tokens.
OpenClaw agents have shell execution, file system read/write, browser automation, and messaging access. CVE-2026-25253 enables remote code execution via URL parameter validation. 21,639 instances found publicly exposed with leaked API keys.
Third-party OpenClaw plugins execute with full agent permissions. A compromised plugin update can introduce backdoors silently. No built-in integrity verification for plugin code changes.
What Rune Does for OpenClaw
Native Interceptor Integration
Hooks into OpenClaw's before_tool_call/after_tool_call pipeline. No monkey-patching, no wrappers — native plugin integration that scans every tool call at the framework level.
Tool Call Scanning
Every tool invocation is scanned before execution. Arguments are checked for injection patterns, command injection, and policy violations. Results are scanned for data exfiltration.
Message Injection Detection
message_sending hook catches prompt injection in messages before they're processed. Protects against attacks via WhatsApp, Telegram, Discord, and all other channels.
Policy Enforcement
YAML policies control which tools OpenClaw can use, what parameters are allowed, and rate limits. Pre-built templates for default, strict, and monitoring modes.
Common OpenClaw Use Cases
- Personal AI assistants with access to email, calendar, and messaging
- Development agents with shell execution and file system access
- Enterprise OpenClaw deployments across multiple channels
- Securing third-party ClawHub skills and plugins
