.wisz File
The Wisz strain is a form of ransomware engineered for Windows, a variant of the STOP/DJVU malware family. Its main action involves locking user files, appending a .wisz extension, and subsequently presenting a note demanding a ransom. Victims are then pushed into paying up to regain access to their files, with the threat that non-payment could mean permanent data encryption. However, this action does not guarantee that you will get back your files.
