How Kitz Ransomware infected your computer

Kitz Ransomware, being a variant of STOP/Djvu Ransomware, typically infects computers through malicious email attachments, software cracks, key generators, or by exploiting vulnerabilities in outdated software. One common method of infection is through phishing emails that contain attachments or links to download infected software. The attachments may be disguised as legitimate files such as PDFs or Microsoft Office documents, but when opened, they execute the malware on the victim’s computer. Another method of infection is through software cracks or key generators. These are illegal methods of activating software without paying for it, and they often come bundled with malware like Kitz Ransomware. Finally, Kitz Ransomware may also exploit vulnerabilities in outdated software to gain access to the victim’s computer. This is why it is crucial to keep software and operating systems up-to-date with the latest security patches to prevent such attacks.
