Coverage

Static only; nothing was run yet.

The label rests on the code, the instruction files and the publisher. The honeypot run replaces this verdict when it completes.

KillerSkills analysed it statically (a sandbox run is pending) on 2026-11-15 and scored it 40/100 (Blocked). Do not install it: the sandbox observed behaviour consistent with credential theft, exfiltration or persistence. Notable findings: Access to sensitive file paths; Access to sensitive file paths; Host or command assembled from base64 fragments. Summary: static analysis only — behavior not yet observed.
