AI Security Review
scanned 3mo ago · by lpm-firewall-aiThe package's public entrypoint automatically performs an unauthenticated remote payload retrieval and execution chain. No user action beyond importing the package is required.
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 attacker-controlled native code executes with the importing process's privileges.
Mechanism
remote payload download, temporary drop, and detached execution
Attack narrative
At import time, index.js loads _adapter.js. The adapter contacts rotated workers.dev hosts for an OS-specific binary, or reconstructs one from DNS TXT records, then drops it under a disguised temporary filename and launches it detached through /bin/sh or cmd.exe. This is a concrete remote-code-execution loader, not telemetry.
AI rationale

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 immediately on package import.
- _adapter.js downloads platform-specific payloads from three workers.dev hosts.
- _adapter.js falls back to DNS TXT payload reconstruction from well1.site domains.
- Downloaded payload is written to /var/tmp or TEMP, made executable, and detached-spawned via shell/cmd.
- Payload delivery uses an unobtrusive /tmp/.analytics_state marker and swallowed errors.
Evidence against
- package.json has no lifecycle scripts, but runtime import is sufficient to trigger the behavior.
