AI Security Review

scanned 25d ago · by lpm-firewall-ai

The package contains a concrete preinstall data-collection and HTTP-send operation. Automatic execution during installation makes this malicious install-time behavior.

Static reason

High-risk behavior combination matched malicious policy.

Trigger

Installing the package runs the preinstall hook.

Impact

Package installation discloses local host and user identity data without an application-level user action.

Mechanism

The hook invokes Node inline, reads the hostname and current user name, and performs an HTTP GET request containing both values.

Attack narrative

On installation, the preinstall lifecycle script runs automatically. It obtains the hostname and current operating-system user name and places them in a request to a local HTTP service. The package description also frames the release as a dependency-confusion proof of concept, but that claim does not remove the active install-time collection and transmission behavior.

AI rationale

The package contains a concrete preinstall data-collection and HTTP-send operation. Automatic execution during installation makes this malicious install-time behavior.
