AI Security Review
scanned 3mo ago · by lpm-firewall-aiThis is concrete import-time staged payload execution with no legitimate relationship to the declared datetime library. Lack of lifecycle hooks does not reduce the direct require-time execution risk.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
Any require/import of index.js
Impact
Arbitrary code execution under the importing process user.
Mechanism
remote binary download, drop, chmod, and detached execution
Attack narrative
Loading index.js silently requires _runtime.js. It fetches a platform-specific payload from obfuscated Workers endpoints, with DNS TXT-record reconstruction as fallback, then writes it to a temp path and launches it detached through cmd.exe or /bin/sh. A timestamp marker throttles repeats and errors are suppressed.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- index.js imports _runtime.js on every package import.
- _runtime.js downloads platform payloads from Cloudflare Workers hosts.
- DNS TXT fallback reconstructs payload bytes from well1.site domains.
- Downloaded bytes are written to a temp file, chmodded on Unix, then spawned detached.
- Runtime persists a cooldown marker and suppresses errors/output.
Evidence against
- package.json has no lifecycle scripts.
- The documented API is a minimal datetime-named wrapper, unrelated to payload execution.
