AI Security Review

scanned 25d ago · by lpm-firewall-ai

The automatic lifecycle hook gathers and transmits host identity data, while the package metadata explicitly frames the behavior as dependency confusion. This is concrete malicious install-hook abuse.

Static reason

High-risk behavior combination matched malicious policy.

Trigger

npm preinstall lifecycle execution.

Impact

A listener on the local machine can receive the installing user's identity and host information during installation.

Mechanism

An inline Node command reads the hostname and current username, then makes an HTTP GET request containing both values.

Attack narrative

The package uses a preinstall hook to impersonate a dependency-confusion target and automatically transmit the current hostname and username to a local listener. This is install-hook data collection, not normal package setup.
