AI Security Review
scanned 3mo ago · by lpm-firewall-aiThis is concealed, automatic host-data exfiltration at install/import time, unrelated to the advertised utilities.
Static reason
One or more suspicious static signals were detected.
Trigger
npm install or requiring the package entrypoint
Impact
Leaks local username, hostname, project-directory basename, and timestamp to a third-party DNS domain.
Mechanism
obfuscated hostname-based DNS exfiltration
Attack narrative
The install lifecycle invokes index.js, which silently loads lib/core.js. That module decodes obfuscated identifiers, reads the current OS username, hostname, and working-directory basename, then embeds them with a timestamp in a DNS label resolved under oob.sl4x0.xyz. The same collector also runs when consumers import the package.
AI rationale
This is concealed, automatic host-data exfiltration at install/import time, unrelated to the advertised utilities.

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` on install.
- index.js silently imports lib/core on install and normal import.
- lib/core.js collects OS username, hostname, cwd basename, and timestamp.
- lib/core.js DNS-resolves encoded telemetry to oob.sl4x0.xyz.
- lib/b02e30.js and lib/6ad264.js conceal the DNS collector's strings.
Evidence against
- src/ contains ordinary utility modules.
- No child-process execution, filesystem writes, or HTTP upload found.
