AI Security Review

scanned 18d ago · by lpm-firewall-ai

Inspected source establishes automatic, unconsented host-information exfiltration during installation. The security-research claim does not excuse this active behavior.

Static reason

One or more suspicious static signals were detected.

Trigger

npm installation invokes the postinstall hook.

Impact

The collector receives the installing machine's hostname, platform, Node.js version, and installation event.

Mechanism

ping.js constructs a URL containing host information and sends an HTTPS GET, suppressing network errors.

Attack narrative

The published package invokes ping.js automatically during installation. That script gathers machine information and sends it to a fixed external webhook without an opt-in gate. Its security-research labeling does not neutralize the active data transfer. The inspected payload is limited to host and runtime information; credential theft was not observed.

Decision evidence

public snapshot

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

Evidence for block

package.json automatically runs ping.js after installation.
ping.js collects the machine hostname, operating system platform, and Node.js version into a webhook.site URL.
ping.js sends the collected data through HTTPS and silently suppresses failures.
Package metadata claims a security-research purpose for dependency confusion; this claim does not establish consent for automatic reporting.

Evidence against

The inspected script does not read credentials or local files.
index.js throws on import instead of providing functional library exports.
