- Document files
- Audio files
- Video files
- Image files
- Backup files
- Banking credentials and data
Every single file that gets encrypted will receive the same extension appended to it, which is .SHARK.
The Shark cryptovirus is set to erase all the Shadow Volume Copies from the Windows operating system with the help of the following command:
→C:\Windows\System32\cmd.exe” /C vssadmin.exe Delete Shadows /All /Quiet
