The .crypt Extension Ransomware – How Did I Get It?
This threat most likely spreads via email. Spoof emailing is a very common strategy if the cyber criminals have decided to target a particular computer that they believe may possess valuable information.

For example, if your mother’s email address is [email protected] it may send you a message with this email address along with a file that may be the ransomware itself. Such files may be any of the most widely used document formats – .docx, .pdf, .xml and others.
Once there, the ransomware may attack some of the Windows processes that are in control and running with the highest priority on the PC. From there it may begin to spread its malicious files that may be keyloggers, password sniffers, .dll files and other tools that encrypt data in different algorithms.
It may create files, change desktop wallpaper, change homepage and others to a custom page that aims to inform the victim with instructions on how much time he has left until the files are gone and how to pay the ransom. Experts advise not to comply with cyber-criminals’ demands and seek professional software, dealing with such types of threats.
