Billy Emergency Repair
Security checks for vulnerabilities and agentic risk
Overview
This skill is narrowly described as Neill-only emergency repair, but it asks an agent to run unbundled local scripts that use SSH keys to change authentication state on a remote Billy system.
Install only if you are Neill or explicitly manage the Billy/SAPCONET environment and have independently reviewed the referenced repair and SSH key setup scripts. Do not use it as a general repair skill or allow it to run without explicit, current authorization.
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
