Security audit

Skill Security Auditor Jack

Security checks for vulnerabilities and agentic risk

Overview

This is a documentation-only security auditing skill that tells an agent to flag risky patterns, not to perform them.

This skill is appropriate for helping review other skills, but its output is intentionally conservative and should be treated as audit guidance rather than an automatic install or reject decision.

A.I.G

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

Credential Access

High
Category
Privilege Escalation
Confidence
60% confidence
Finding

Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.

- `eval`, `exec`, `Function()` — code execution
- `curl` / `wget` with pipe to shell — remote code download
- `chmod +x` / `sudo` — privilege escalation
- Reading `~/.ssh`, `/etc/passwd`, environment secrets
- Network calls to unknown hosts
- Base64-encoded or obfuscated commands
- Install scripts that fetch from unknown URLs
