CYR-Locker Ransomware Description

Security experts have uncovered a new scareware virus known as the CYR-Locker which poses as a dangerous malware. The initial reports indicate that it has been based on unknown code. The complete is not yet available and we do not know if it features a working encryption engine.

Upon infection the CYR-Locker ransomware creates and launches a screenlocker. This is an application overlay that prohibits ordinary interaction with the victim computer. They are popular with advanced viruses as they can easily scare most users into paying the ransom fee.

The following message is displayed:

Many of the fake ransomware variants can easily be removed by entering a random key if they are of the basic type. This one however does not seem to be of this type.
