AI Security Review

scanned 27d ago · by lpm-firewall-ai

LPM flags this version as an AI-agent control-surface risk. A global npm installation automatically changes agent configuration in the user's home directory. It adds always-on hooks and can register a local agent plugin and marketplace entry.

Static reason

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

Trigger

Installing the package globally through npm.

Impact

Claude, Codex, ChatGPT desktop, and Hermes agent behavior can be altered without an explicit setup command or consent prompt.

Mechanism

Postinstall-driven AI-agent configuration and hook installation.

Policy narrative

A global npm install runs the postinstall script, which calls setupGlobal. That code detects agent homes and installs instruction cards, skills, and persistent command hooks. Where Codex is available, it can additionally create a plugin tree and register it in the shared local agent marketplace. This is an unconsented install-time mutation of broad AI-agent control surfaces.

AI rationale

The package has a concrete automatic postinstall chain that modifies multiple AI-agent homes and installs hooks, rather than requiring an explicit setup command. This meets the install-control-surface blocking policy even though this inspection found no secret exfiltration or self-dependency chain.
