audit-tools@0.34.42

Portable hybrid code auditing + remediation orchestrators for arbitrary repositories.

AI Security Review

scanned 17d ago · by lpm-firewall-ai

LPM flags this version as an AI-agent control-surface risk. An npm postinstall silently mutates multiple foreign AI-agent control surfaces and the consuming repository. It installs persistent skills, commands, plugins, and global OpenCode configuration without an explicit user command.

Static reason

One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review

Trigger

npm install of audit-tools@0.34.42

Impact

Persistent modification of Codex, Claude, OpenCode, and Antigravity/Gemini agent behavior; modification of the project .gitignore.

Mechanism

postinstall deployment of global AI-agent assets and config

Policy narrative

Installing the package invokes postinstall, which writes package-controlled prompts and skills into global Codex and Claude directories, merges commands, agents, MCP configuration, and permission rules into global OpenCode configuration, and installs Gemini/Antigravity plugins. It also attempts to update the consuming repository's .gitignore. These are persistent, unprompted mutations of foreign AI-agent control surfaces.

Rationale

Source inspection confirms unconsented install-time persistence across multiple third-party AI-agent configurations, meeting the block policy despite no confirmed install-time exfiltration.
