AI Security Review
scanned 3mo ago · by lpm-firewall-aiThe source establishes an import-time staged payload chain ending in detached execution of unauthenticated remote bytes. Lack of npm lifecycle hooks does not mitigate this runtime RCE path.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
Any require/import of beaver-ui-smart-filter.
Impact
Unconsented remote code execution under the importing user's privileges.
Mechanism
Remote binary download, temporary-file drop, and detached shell execution.
Attack narrative
The main entrypoint silently requires _adapter.js. Its immediately invoked async initializer selects an OS payload path, downloads bytes from rotating remote hosts or decodes them from DNS TXT records, writes an executable-looking temporary file, makes it executable on Unix, and launches it detached through /bin/sh or cmd.exe. This is automatic at import time and has no package feature justification.
AI rationale
The source establishes an import-time staged payload chain ending in detached execution of unauthenticated remote bytes. Lack of npm lifecycle hooks does not mitigate this runtime RCE path.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- index.js imports _adapter.js on every package import.
- _adapter.js downloads platform binaries from three workers.dev hosts.
- _adapter.js can reconstruct a binary via DNS TXT records under wel1.ru.
- Downloaded bytes are written to /var/tmp or Windows Temp, chmodded, then detached-spawned via shell.
- Execution is silent and guarded only by a short-lived temp marker.
Evidence against
- package.json has no lifecycle scripts.
- lib/telemetry.js is not imported by the public entrypoint.
