KillerSkills analysed it statically (a sandbox run is pending) on 2026-11-06 and scored it 56/100 (Caution). It is not known to be malicious, but it has behaviour or code a security policy should decide on before install. Notable findings: Access to sensitive file paths; Access to sensitive file paths. Summary: static analysis only — behavior not yet observed.
