AI Security Review
scanned 9d ago · by lpm-firewall-aiThe manifest activates an install-time probe that automatically sends identifying network metadata to a publisher-selected endpoint. This matches the installation beacon policy and supports blocking publication.
Static reason
One or more suspicious static signals were detected.
Trigger
The package’s postinstall hook runs during installation.
Impact
The endpoint receives the installer’s public egress IP, identifying the installation environment.
Mechanism
The script queries public IP lookup services, then requests the Zireku probe endpoint with the discovered IP in the query string; no installer consent guard is present.
Attack narrative
During installation, the postinstall hook launches a script that discovers the installer’s public IP through external lookup services and sends it to the package’s Zireku endpoint. The source shows no consent guard for this disclosure.
AI rationale
The manifest activates an install-time probe that automatically sends identifying network metadata to a publisher-selected endpoint. This matches the installation beacon policy and supports blocking publication.

Decision evidence
public snapshotAI called this Malicious at 96.0% confidence as Malware with low false-positive risk.
Evidence for block
- The postinstall hook automatically runs scripts/install-probe.js.
- The script queries public IP lookup services to obtain the installer’s public IP.
- It sends that IP as an `ip` query parameter to the Zireku probe endpoint without an effective consent guard.
- The probe runs immediately when the script is invoked.
