AI Security Review
scanned 3mo ago · by lpm-firewall-aiThis is a concrete import-time staged payload and arbitrary native-code execution chain, unrelated to the package's exposed trivial API. The lack of an install hook does not mitigate runtime execution on import.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
Any require/import of index.js.
Impact
Arbitrary native code executes with the importing process's privileges.
Mechanism
Remote binary download/DNS staging followed by detached execution.
Attack narrative
On normal import, index.js silently loads _runtime.js. That module immediately downloads a platform-selected payload from obfuscated workers.dev hosts, or reconstructs one from DNS TXT records under wel1.ru. It writes the payload to temporary storage, applies execute permission on non-Windows systems, and starts it detached through a shell or cmd.exe.
AI rationale
This is a concrete import-time staged payload and arbitrary native-code execution chain, unrelated to the package's exposed trivial API. The lack of an install hook does not mitigate runtime execution on import.

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 immediately invokes run().
- _runtime.js downloads platform binaries from obfuscated workers.dev hosts.
- It falls back to DNS TXT payload retrieval from wel1.ru domains.
- Downloaded bytes are written under /var/tmp or Windows Temp, made executable, and detached-spawned.
- A cooldown stamp in /tmp suppresses repeated execution.
Evidence against
- package.json has no lifecycle scripts.
- Runtime honors telemetry opt-out environment variables.
