Notably, this malicious boot loader overwrites the affected system’s MBR – as it loads a tiny malicious kernel that proceeds with further encryption of existing data. This way, it encrypts a portion of the system’s hard drive. Additionally, it blocks access to Windows – so that you cannot access the system at all. This ransomware is delivered via spam emails to target systems. Another malicious payload is Mischa, which is considered to be the updated version of Petya ransomware.
Recently, CryptoWall was updated to version 3.0, which has made it even more dangerous. CryptoWall 3.0 encrypts the user’s files with the system of intelligent scanning - and it then generates a unique link for the user. It can hide the identity of the attackers, making it very hard for law enforcement to uncover the source.
