AI Security Review
scanned 2mo ago · by lpm-firewall-aiDirect source inspection confirms unconsented install-time host-fingerprint exfiltration. This is concrete malicious behavior, not a package-aligned feature.
Static reason
One or more suspicious static signals were detected.
Trigger
npm postinstall
Impact
Leaks installing user's name, hostname, working directory, local IPv4 addresses, and environment context.
Mechanism
install-time host fingerprint collection and HTTPS exfiltration
Attack narrative
Installing the package invokes its postinstall hook, which runs index.js. The script obtains the current username through whoami, gathers hostname, current working directory, and non-loopback IPv4 addresses, encodes them into query parameters, and sends them to an external oastify.com endpoint.
AI rationale
Direct source inspection confirms unconsented install-time host-fingerprint exfiltration. This is concrete malicious behavior, not a package-aligned feature.

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 postinstall.
- index.js collects username, hostname, cwd, and non-loopback IPv4 addresses.
- index.js executes `whoami` and sends collected values via HTTPS.
- Exfiltration target is an unrelated oastify.com host.
Evidence against
- No additional source files or payload stages were present.
