ransomware

CryptBIT 2.0 is a new variant of file-encrypting malware, also known as ransomware. It represents a continuation of the CryptBIT ransomware under a new name and in a new package.

CryptBIT 2.0 will encrypt most files on a system, change its desktop wallpaper and then deposit its ransom demands inside a text file.

Encrypted files will go through a name change, having the extension ".cryptbit" appended after their original one. This will turn a file called "image.jpg" into "image.jpg.cryptbit".
