Kovter is a dangerous money-extorting malware that belongs to the group of ransomware viruses. It was first recorded in May, 2014 and since then the threat has spread through the globe and infected thousands of computers. Kovter operates in the same manners as its forerunners – it overtakes a system and demands money for its restitution. Lately Kovter, however, exploited the disguise of governmental accusation. It blocked the screen with the notification of user’s law breaching and stated that there was a fine for the crimes.
