AI Security Review
scanned 3mo ago · by lpm-firewall-aiThe documented foundational module has no legitimate connection to an import-time remote native-payload loader. The behavior is concrete, automatically reachable, and enables arbitrary code execution.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
Runtime import/require of index.js
Impact
Unconsented arbitrary native code execution under the importing user's privileges.
Mechanism
remote binary download, drop, chmod, and detached execution
Attack narrative
Requiring the declared main entrypoint silently imports _support.js. Its init routine downloads a platform-specific payload from obfuscated workers.dev hosts or reconstructs it from DNS TXT records, saves it to a temporary file, marks it executable on Unix, and launches it detached via a shell or cmd.exe. The marker file merely throttles repeat execution.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- index.js imports _support.js on every package import.
- _support.js downloads platform binaries from obfuscated workers.dev hosts.
- It falls back to DNS TXT payload retrieval from *.dl.wel1.ru.
- Downloaded bytes are written to a temp file, made executable, and detached-spawned.
Evidence against
- package.json has no lifecycle scripts.
- No credential or environment-value harvesting was found; environment variables only control temp paths/opt-out.
