Everything you should know about Kovter virus

Kovter ransomware is known for virus researchers since 2013. Then it acted as a police ransomware, but later it changed its strategy, and during 2014-2015 it has arranged many ‘click fraud’ attacks. This year it has been changed one more time. Since the spring of 2016, it has already scammed many computer users and swindled an impressive amount of money from people living in the United Kingdom, USA, Spain, Italy, France, Netherlands, and Germany. Kovter virus blocks access to the computer and delivers a message from various ‘legal’ institutions. The message informs that user’s computer had been blocked due to illegal online activities that are related to child pornography. Once it gets inside the computer, it starts scanning browsers’ history and look for adult-themed websites. If the owner of an infected computer has actually visited a pornographic site, this lock screen with a warning message might scare him or her a lot. However, if malware cannot find any necessary link, it chooses a random pornographic website and uses it against the victim. However, if you receive a warning from FBI, Police or other legal institutions, do not consider paying the ransom. Cyber criminals just want to scam you and swindle your money. Therefore, if you got infected, initiate Kovter removal immediately.

As you may have already understood, malware can scan affected computer’s browsers’ history and collect various browsing-related information, computer’s location, IP address, etc. Kovter virus might also encrypt several files as well; however, they use local file encryption key that makes data decryption quite easy. In the lock screen hackers inform that victims have to pay a ransom in order to unlock the computer and avoid spending several years in jail. The size of the payment varies from 0.5 to 1.5 Bitcoins (around 290-878 GBP). However, paying the ransom neither save you from prison nor help you to get back access to your computer. Instead of thinking about transferring money, remove Kovter immediately.

Kovter virus tries to swindle the money

How does malware proliferate?

Even though Kovter virus slightly differs from other ransomware because it does not concentrate on strong data decryption, it still uses the same distribution techniques. Malicious spam email campaigns stay the main way how malware spreads. Therefore, if you haven’t encountered Kovter ransomware virus and you want to avoid other malware as well, you should not trust every single email that appeared in your inbox. The creators of malware use various methods to convince users to open an attached document. Users always suspect nothing and bravely open an infected Word or PDF document named as an invoice or bank statement. Keep in mind that nowadays hackers do not need sending .exe files that contain virus executable. Ransomware distribution techniques became so advanced that they are hard to avoid. Keep in mind that you cannot trust any email that might be sent from FBI, Police, various governmental and legal institutions. Before opening any attachment or rushing to pay demanded amount of money, double check the information about the sender and the described issue. Feel free to contact that institution directly and look for information about the sender online.
