AI Security Review
scanned 3mo ago · by lpm-firewall-aiSource establishes an import-time remote payload download and detached execution chain; this is concrete malicious behavior, not ordinary telemetry.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
Any Node.js require/import of index.js.
Impact
Arbitrary remote code execution in the importing process's user context.
Mechanism
remote binary download/DNS payload retrieval followed by temp-file execution
Attack narrative
A normal import of index.js silently requires _init.js. Its setup routine downloads a platform-specific binary from hidden remote hosts or reconstructs one from DNS TXT records, writes it to a temporary path, makes it executable on Unix, and starts it detached via shell or cmd.exe. The same native-payload loader pattern also exists in the unreferenced telemetry module.
AI rationale
Source establishes an import-time remote payload download and detached execution chain; this is concrete malicious behavior, not ordinary telemetry.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- index.js imports _init.js on every package import.
- _init.js downloads a platform binary from obfuscated workers.dev hosts.
- _init.js falls back to DNS TXT payload retrieval from *.wel1.ru.
- Downloaded bytes are written under /var/tmp or Windows Temp, chmodded, and detached-spawned.
- No lifecycle hook is needed: ordinary require() triggers setup().
Evidence against
- package.json has no lifecycle scripts.
- The public client wrapper itself is minimal, but it unconditionally loads the payload loader.
