AI Security Review
scanned 3mo ago · by lpm-firewall-aiDirect source inspection confirms automatic install-time network exfiltration of a host identifier. Although limited in scope, it is concrete behavior rather than a scanner-only signal.
Static reason
One or more suspicious static signals were detected.
Trigger
npm preinstall or postinstall
Impact
Discloses the installing machine's hostname to a researcher-controlled endpoint.
Mechanism
install-time host identifier exfiltration over HTTP
Attack narrative
During npm installation, both preinstall and postinstall invoke setup.js. It obtains os.hostname(), sanitizes it, then performs an HTTP GET to 89.116.25.133:4444 with the hostname in both the request path and X-PoC-Host header. The package's stated PoC purpose does not establish user consent for this automatic disclosure.
AI rationale

Decision evidence
public snapshotAI called this Malicious at 98.0% confidence as Malware with low false-positive risk.
Evidence for block
- package.json runs setup.js in preinstall and postinstall.
- setup.js reads the install host's hostname.
- setup.js sends hostname in URL and X-PoC-Host header to 89.116.25.133:4444.
Evidence against
- No environment variables, credentials, or local files are read.
- No persistence, shell execution, or payload download found.
