Clawhub Verify
Security checks for vulnerabilities and agentic risk
Overview
This skill is a small verification helper that sends a server address to brick.blue for safety and pricing checks before a user connects.
Installers should understand that endpoint URLs submitted for verification are shared with brick.blue, and a fresh verification can trigger live calls from brick.blue to the target server. Avoid using it on private or sensitive internal endpoints unless that disclosure and probing behavior is acceptable.
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
- 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
- Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs
Vulnerability Patterns
- Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
- Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
- Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
- Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code
- Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep
