KratosCrypt Ransomware – Infection Spread
KratosCrypt ransomware is probably spread mainly with spam email campaigns. Spam emails have files attached to them. Malicious code hides inside the attachments very often. And when you open such an attachment, your computer gets infected. A curious fact about that is some malware creators make the sole body of the email contain the malicious code, where you might get infected just by opening the email letter.
Social media sites and services for file-sharing could have malware files, which might have been uploaded by the criminals. To avoid most of the chances of getting infected with ransomware you have to be wary around what you click, open and download while surfing the Internet. Suspicious links and files of unknown origin could help with the spread of the infection, especially if they contain malicious code.
