Security audit

ChainWard

Security checks for vulnerabilities and agentic risk

Overview

This skill is a coherent ChainWard wallet-monitoring helper, but users should understand it installs an external CLI and uses a ChainWard API key.

Install only if you trust ChainWard and are comfortable giving its CLI access to CHAINWARD_API_KEY. Review the npm package/version you install, keep the API key limited to ChainWard use, and check ~/.chainward/config.json and alert delivery channels for sensitive configuration.

A.I.G

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

Session Persistence

Medium
Category
Rogue Agent
Confidence
60% confidence
Finding

Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.
