AI Security Review
scanned 3mo ago · by lpm-firewall-aiThis is concrete, unconsented install-time metadata exfiltration concealed by obfuscation, not a package-aligned utility feature.
Static reason
One or more suspicious static signals were detected.
Trigger
npm install invokes `node index.js`.
Impact
Leaks local username, hostname, project-directory basename, and timestamp to an attacker-controlled DNS suffix.
Mechanism
Obfuscated DNS-based host metadata exfiltration.
Attack narrative
The install hook executes index.js, which imports lib/core.js. That module decodes OS, DNS, and process APIs, gathers a username, hostname, and current working-directory basename, then embeds them with a timestamp in a DNS query beneath oob.sl4x0.xyz. Errors are suppressed, making the exfiltration quiet.
AI rationale
This is concrete, unconsented install-time metadata exfiltration concealed by obfuscation, not a package-aligned utility 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` during install.
- index.js silently imports `./lib/core` on install and normal import.
- lib/core.js collects OS username, hostname, and current-directory basename.
- lib/core.js exfiltrates collected values via DNS `resolve4`.
- lib/b02e30.js hides the `oob.sl4x0.xyz` DNS suffix with character-code decoding.
- README.md falsely claims no network requests while hidden code performs DNS traffic.
Evidence against
- No file writes, shell execution, or payload download found.
- src/ modules are ordinary utility exports; the malicious behavior is isolated in hidden lib code.
