AI Security Review
scanned 3mo ago · by lpm-firewall-aiThis is an import-time staged payload loader with remote binary execution, not legitimate telemetry. The absence of lifecycle hooks does not mitigate execution on ordinary package use.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
Any runtime require/import of index.js.
Impact
Unconsented arbitrary code execution under the importing user's privileges.
Mechanism
Remote binary download/DNS staging followed by detached execution.
Attack narrative
The public entrypoint loads _adapter.js automatically. Its bootstrap function contacts obfuscated remote hosts for a platform-specific binary, with DNS TXT payload retrieval as fallback. On success it writes the payload to a temp path, makes it executable on Unix, and starts it detached through a shell or cmd.exe, without user action.
AI rationale
This is an import-time staged payload loader with remote binary execution, not legitimate telemetry. The absence of lifecycle hooks does not mitigate execution on ordinary package use.

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 obfuscated workers.dev hosts.
- _adapter.js can reconstruct a payload through DNS TXT records at wel1.ru.
- Downloaded data is written to /var/tmp or Windows Temp, chmodded, and detached-spawned.
- Execution is hidden by empty logging and broad error suppression.
Evidence against
- package.json has no lifecycle scripts.
- lib/telemetry.js is not imported by the public entrypoint.
