Feishu/Lark Setup and Troubleshooting
Security checks for vulnerabilities and agentic risk
Overview
This skill is a straightforward Feishu/Lark troubleshooting guide for Hermes Agent with disclosed, purpose-aligned commands and no hidden execution behavior.
Before installing, be aware that troubleshooting may expose Feishu/Lark app secrets or gateway logs to the local agent. Use an allowlist in production, avoid sharing logs containing sensitive values, and restart the gateway only when you intend to apply configuration changes.
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
