Episode notes
Delay And Inspect Dependency Updates
- Check dependency versions and lockfiles immediately after supply-chain incidents and audit for malicious postinstall scripts.
- Wes Bos recommended using pnpm features like minimumReleaseAge and approving scripts to delay and block malicious quick releases.
Semver Point Releases Enable Rapid Supply Chain Attacks
- The Axios compromise used a semver point release and a post-install script to drop a RAT (Remote Access Trojan) on developer machines.
- Because many projects depend on Axios transitively, even non-axios users could have executed the malicious postinstall.
Sandbox Agent Workloads Instead Of YOLOing Locally
- Run third-party or agent code in sandboxes and avoid running everything locally with full privileges.
- Wes Bos warned that postinstall scripts can execute arbitrary code and recommended sandboxing and stricter approvals while agents and tools mature.
