audit-tools@0.36.0

Portable hybrid code auditing + remediation orchestrators for arbitrary repositories.

AI Security Review

scanned 7d ago · by lpm-firewall-ai

LPM flags this version as an AI-agent control-surface risk. npm postinstall silently installs global AI-agent commands, skills, plugins, and OpenCode configuration. It also modifies the consuming project's .gitignore.

Static reason

High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review

Trigger

npm install of audit-tools

Impact

Changes behavior and permissions of Codex, Claude, OpenCode, and Gemini/Antigravity without an explicit setup command.

Mechanism

install-time mutation of global AI-agent control surfaces

Policy narrative

Installing the package automatically launches two host-asset deployers. They write global Codex and Claude skills/commands, global OpenCode configuration, Antigravity plugins, and a Claude Desktop plugin; no user command opts into this setup. The top-level postinstall also changes the consuming repository's .gitignore.

Rationale

This is a concrete unconsented postinstall mutation of multiple foreign, global AI-agent control surfaces. Hardened permission defaults do not remove the install-time control-surface takeover.
