AI Security Review
scanned 3mo ago · by lpm-firewall-aiSource directly confirms unconsented install-time host fingerprint exfiltration. The nested archive contains the same malicious 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 installation
Impact
Leaks host identity, home-directory location, and configured DNS resolvers to a third party.
Mechanism
collects host metadata and POSTs it externally
Attack narrative
Installing the package invokes index.js through preinstall. The script gathers local host and DNS metadata, serializes it, and sends it to an external OAST endpoint without consent.
AI rationale
Source directly confirms unconsented install-time host fingerprint exfiltration. The nested archive contains the same malicious 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, home directory, platform, architecture, and DNS servers.
- index.js POSTs collected host data to an external oastify.com host.
- Manifest describes a dependency-confusion proof of concept.
