VirLocker is in no way new, it has been making a mess of victim’s machines for quite a few years now. VirLocker was the first example of a mainstream polymorphic ransomware and it left no expense of misery to its victims.
VirLocker can of course be propagated like any other malware from its author, but VirLocker has a trick up its sleeve when it comes to infecting other users. Because every file that VirLocker touches becomes VirLocker itself, so many users will accidentally send an infected version of a file to friends and colleagues, backups become infected, and even applications and EXE’s are not safe.
