AI Security Review
scanned 3mo ago · by lpm-firewall-aiThis is a concrete import-time remote-code-execution chain, not ordinary telemetry. The telemetry module contains a similarly capable configurable downloader, reinforcing the malicious payload-delivery intent.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
Any Node process that imports or requires index.js.
Impact
Arbitrary attacker-controlled native code executes as the importing user's account.
Mechanism
import-time remote payload download, disk drop, and detached execution
Attack narrative
The main entry point silently imports _runtime.js. Its immediately invoked run() writes a rate-limit marker, downloads a platform-specific binary from obfuscated workers.dev hosts or retrieves a base64 payload through DNS TXT records, writes it to a temporary directory, marks it executable on Unix, and launches it detached through a shell or cmd.exe. There is no signature or hash validation.

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 on every package import.
- _runtime.js downloads platform payloads from workers.dev hosts.
- _runtime.js falls back to DNS TXT payload retrieval from dl.wel1.ru.
- _runtime.js writes payloads under /var/tmp or Windows Temp, chmods them, and spawns them detached.
- Download, marker, and execution errors are suppressed.
Evidence against
- package.json has no lifecycle hooks.
- lib/telemetry.js exports a user-invoked run(opts) API, but does not mitigate _runtime.js import execution.
