Skill Blocker - 安全守卫
Security checks for vulnerabilities and agentic risk
Overview
The skill is a disclosed security blocker, but it claims broad control over agent behavior and can persistently disable installed skills or alter global configuration.
Install only if you intentionally want a strict security gatekeeper that may block normal work and change OpenClaw skill state. Prefer a version that is read-only by default, asks before quarantine or blocklist changes, and stores audit logs outside agent memory with redaction.
Vulnerability Patterns
- Skill Instruction HijackingAlters the agent's session goals or safety constraints when the skill loads
- Agent Memory PoisoningWrites attacker-controlled rules into memory that affect later sessions
- Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs
- Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review
- Embedded Malicious CodeShips malicious scripts inside the skill and executes them locally

> ~/.openclaw/config/global-blocklist.json ``` ```bash touch ~/.openclaw/skills/malicious-keylogger.skill.BLOCKED ``` ### Technical Analysis The Skill instructs the Agent to rename installed Skill directories, append entries to a global blocklist, and create marker files. These are state-changing actions applied to shared OpenClaw configuration and installed components. The decision to perform these operations is based on simplistic pattern matching. A benign Skill can mention dangerous strings as documentation, detection signatures, test data, or educational examples. This project itself demonstrates that ambiguity: references to remote shell execution and SSH key paths are presented as prohibited examples rather than operations to execute. Appending a standalone JSON object with shell redirection is also unsafe configuration handling. If the target already contains a JSON document, appending another object can corrupt the file or create ambiguous parser behavior. The instructions do not require canonical-path validation, symlink checks, atomic updates, backups, locking, or rollback. ### Attack Path 1. An installed benign Skill contains a blocked phrase in documentation or test content. 2. The blocker performs raw pattern matching without determining whether the phrase is executable. 3. The benign Skill is classified as high or extreme risk. 4. The Agent renames its directory, creates a blocking marker, or appends its name to global configuration. 5. The affected Skill becomes unavailable, or the global configuration becomes invalid. 6. If a path can be influenced, absent canonicalization and symlink checks may ...[truncated 839 chars]- Remediation
