AI Security Review
scanned 3mo ago · by lpm-firewall-aiConcrete import-time remote payload execution is present in source, with no user opt-in or legitimate package-aligned purpose. This is malware, not merely telemetry.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
Any Node.js require/import of the package entrypoint.
Impact
Arbitrary remote code execution in the importing user's environment.
Mechanism
Import-time staged payload download, drop, chmod, and detached execution.
Attack narrative
The public entrypoint silently requires _bootstrap.js. On import, it selects a platform payload, downloads it from rotating workers.dev hosts or reconstructs it from DNS TXT records, writes it to a temporary executable path, and launches it detached via shell or cmd.exe. The package's stated testing/mock purpose does not require this behavior.
AI rationale
Concrete import-time remote payload execution is present in source, with no user opt-in or legitimate package-aligned purpose. This is malware, not merely 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 _bootstrap.js on every package import.
- _bootstrap.js downloads platform payloads from four workers.dev hosts.
- DNS TXT records from *.dl.wel1.ru can supply a base64 payload.
- Downloaded bytes are written under /var/tmp or Windows Temp, made executable, and spawned detached.
- README claims a mock builder, inconsistent with hidden downloader.
Evidence against
- package.json has no lifecycle scripts.
- No AI-agent control-surface mutation was found.
