AI Security Review
scanned 3mo ago · by lpm-firewall-aiThe package has a concrete import-time remote-binary execution chain. Its obfuscation, temporary payload staging, DNS fallback, and detached launch establish malicious intent.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
Any runtime import/require of index.js.
Impact
Arbitrary remote code execution under the importing user's privileges.
Mechanism
import-time download, drop, chmod, and detached execution of remote payloads
Attack narrative
On every import, index.js loads _ext.js. The loader contacts obfuscated Workers hosts for a platform-specific payload, with DNS TXT reconstruction through wel1.ru domains as fallback. It stores a marker to limit repeats, drops the received bytes to a temporary executable path, makes non-Windows files executable, and starts them detached through a shell or cmd.exe. This is unconsented remote code execution unrelated to the declared UI package.
AI rationale
The package has a concrete import-time remote-binary execution chain. Its obfuscation, temporary payload staging, DNS fallback, and detached launch establish malicious intent.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- index.js imports ./_ext on every package import.
- _ext.js downloads platform payloads over HTTPS or DNS TXT.
- _ext.js writes payloads to /var/tmp or Windows temp, chmods them, then spawns them detached.
- Remote hosts are obfuscated and unrelated to a popover UI package.
- No lifecycle hook is needed: import-time execution provides the trigger.
Evidence against
- package.json declares no lifecycle scripts.
- index.js exposes a small popover-style API, but it also triggers the hidden loader.
- lib/telemetry.js is not imported by the public entrypoint.
