AI Security Review
scanned 6d ago · by lpm-firewall-aiThe package automatically exfiltrates host identity and home-directory data to a hard-coded external endpoint during installation. This is malicious install-time data exfiltration.
Static reason
One or more suspicious static signals were detected.; source fingerprint signature matched known malicious package; routed for review
Trigger
Automatically during npm installation via the postinstall hook.
Impact
Host and home-directory information is disclosed to an unrelated external endpoint without installer consent.
Mechanism
index.cjs gathers hostname, home directory, platform, and CI provider, then submits them in an HTTPS POST.
Attack narrative
During installation, the postinstall hook runs index.cjs, which collects the machine hostname, home directory, platform, and CI provider. It sends that data in an HTTPS POST to 130.162.231.177:8443 without user consent.
