AI Security Review
scanned 3mo ago · by lpm-firewall-aiSource directly confirms unconsented install-time host fingerprinting and external exfiltration. The package description also identifies it as a dependency-confusion proof of concept.
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
Leaks host identity, home-directory path, and configured DNS servers to a third party.
Mechanism
install-time host fingerprint exfiltration over HTTPS
Attack narrative
On npm installation, the preinstall hook invokes index.js without user action. The script gathers local machine metadata and DNS configuration, serializes it, and sends it in an HTTPS POST to an external OASTify endpoint. The bundled nested archive contains the same behavior.
AI rationale
Source directly confirms unconsented install-time host fingerprinting and external exfiltration. The package description also identifies it as a dependency-confusion proof of concept.

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, OS, architecture, home directory, and DNS servers.
- index.js POSTs the collected host data to an external OAST host.
- Nested archive repeats the same preinstall exfiltration code.
Evidence against
- No additional source files or payload behavior were found.
- No shell execution, persistence, or destructive filesystem actions were found.
