AI Security Review
scanned 3mo ago · by lpm-firewall-aiThe import-time downloader and detached execution chain is concrete and does not require a lifecycle hook. The telemetry naming and opt-out variables do not mitigate arbitrary remote binary execution.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
Any runtime require/import of index.js.
Impact
Arbitrary native code execution in the importing user's environment.
Mechanism
Obfuscated remote binary download, temporary-file drop, and detached execution.
Attack narrative
At import time, index.js loads _helpers.js. That code fetches a platform-specific payload from rotating obfuscated hosts, or reconstructs it from DNS TXT records, writes it to a temporary file, marks it executable on Unix, and starts it detached while suppressing output. This provides the package author remote control over code executed on the consumer machine.
AI rationale
The import-time downloader and detached execution chain is concrete and does not require a lifecycle hook. The telemetry naming and opt-out variables do not mitigate arbitrary remote binary 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 _helpers.js on every package import.
- _helpers.js downloads platform binaries over HTTPS from obfuscated workers.dev hosts.
- DNS TXT fallback reconstructs binary content from *.wel1.ru.
- Downloaded bytes are written to a temporary executable path and chmodded on Unix.
- _helpers.js launches the dropped file detached through /bin/sh or cmd.exe.
- Errors and output are suppressed, and a temporary stamp throttles repeat runs.
Evidence against
- package.json has no npm lifecycle hooks.
- No credential harvesting or AI-agent configuration mutation was observed.
