AI Security Review
scanned 3mo ago · by lpm-firewall-aiThis is a concrete, automatic remote-code-execution chain activated by normal module import. The absent npm lifecycle hook does not mitigate the import-time behavior.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
Any application importing or requiring index.js
Impact
Unconsented arbitrary native code execution on the host.
Mechanism
import-time download, drop, chmod, and detached execution
Attack narrative
Importing index.js silently loads _init.js. The initializer contacts rotating remote hosts for a platform-specific binary, with DNS TXT records as fallback; it stores the bytes under a temporary random name, makes non-Windows payloads executable, and starts them detached through /bin/sh or cmd.exe. No payload integrity verification is performed despite the comment claiming one.

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 require.
- _init.js downloads platform payloads from three workers.dev hosts.
- _init.js falls back to DNS TXT payload retrieval from wel1.ru.
- Downloaded bytes are written, chmodded, and detached-spawned via shell/cmd.
- Network execution is hidden behind telemetry-like names and empty error logging.
Evidence against
- package.json has no lifecycle scripts.
- lib/telemetry.js requires caller-supplied endpoints, but is not the import-time trigger.
