Security audit

GoG-ifocus

Security checks for vulnerabilities and agentic risk

Overview

This skill is a coherent Google Workspace CLI helper, but it asks users to install an unpinned third-party executable and grant broad Google account access.

Review the gog CLI and its Homebrew tap before installing, grant only the Google services you actually need, avoid unattended mutating commands unless you have checked the target account and document IDs, and be prepared to revoke the OAuth grant if you no longer use it.

Vulnerability Patterns
  • Insecure DependenciesIntroduces malicious components through unsafe dependency sources
  • 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

Credential Access

Category
Privilege Escalation
Confidence
70% confidence
Finding

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