AI Security Review

scanned 2d ago · by lpm-firewall-ai

LPM flags this version as an AI-agent control-surface risk. The npm postinstall hook automatically adds agent profiles and skills to the user's GitHub Copilot control surface when no interactive terminal is available.

Static reason

High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review; previous stored version diff introduced dangerous source

Trigger

Package installation with lifecycle scripts enabled, successful binary provisioning, and no available interactive terminal.

Impact

Package-supplied instructions become available to the user's AI coding harness beyond the installed package.

Mechanism

The hook defaults to GitHub Copilot and copies bundled agent and skill files into its user-level directories without confirmation.

Policy narrative

Installation activates the postinstall hook. After binary provisioning, the hook attempts harness asset setup. When no terminal is available, it selects GitHub Copilot automatically and writes bundled agent profiles and skills beneath the user's home directory. This mutates a foreign AI-agent control surface without consent. Interactive prompts and preservation of customized files do not guard the noninteractive creation path.

AI rationale

Inspected source establishes unconsented postinstall mutation of a foreign user-level AI-agent control surface, which meets the supplied blocking policy. The verdict does not rely on scanner similarity labels or inferred credential theft.
