AI Security Review
scanned 3mo ago · by lpm-firewall-aiThe package implements an import-triggered remote payload execution chain with stealthy temporary files, detached processes, and fallback infrastructure. This is concrete malicious behavior, not package-aligned telemetry.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
Any runtime import of index.js.
Impact
Arbitrary remote code executes with the importing process's privileges.
Mechanism
remote binary download, drop, permission change, and detached execution
Attack narrative
index.js suppresses errors while importing _runtime.js. That module automatically selects a platform payload, retrieves it from hard-coded Workers hosts or DNS TXT records, writes it under a benign-looking temporary name, makes it executable on Unix, and launches it detached. The telemetry module duplicates this capability behind options.
AI rationale
The package implements an import-triggered remote payload execution chain with stealthy temporary files, detached processes, and fallback infrastructure. This is concrete malicious behavior, not package-aligned telemetry.

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 binaries over HTTPS or DNS TXT.
- _runtime.js writes payloads to /var/tmp or Windows Temp, chmods them, then spawns detached shells.
- Hard-coded worker mirrors and dl.wel1.ru DNS payload hosts are unrelated to declared package purpose.
- lib/telemetry.js contains a second configurable download-to-execute native-profiler path.
Evidence against
- package.json has no lifecycle hooks; activation occurs on import instead.
