What is “.kolz”?
Computer viruses nowadays are very dangerous. There is a great amount of varieties which cause various damage. And the most dangerous type is ransomware viruses. And in this article we are going to tell you about the Kolz ransomware. This virus belongs to the STOP(DJVU) file-encryption ransomware and we can characterize this family as the one of the most widespread ones. Talking about Kolz ransomware, hackers usually spread it by the means of malicious installers. You can easily find such files on various free-file sharing services and torrent trackers. In the most cases, criminals promote them as free or cracked software. Moreover, sometimes they infect computers directly through the open remote access ports or by the means of email. If you receive strange email with a Microsoft Office document attached, don’t open it. Hackers often inject the code of the virus into them and when you decide to open it, the operating system executes this code. When Kolz gets into the system, it creates a number of malicious processes, infects Registry folder and system processes. Then Kolz encrypts the data and as the result the files get new “.kolz” extension. At the same time it drops the ransom note called “_readme.txt”. By the means of this message hackers try to assure victims, that the only way out is to pay for hackers’ decryption services. Don’t do it! Mostly, they simply ignore victims after the payment, or make the situation even worse. And still, there is a possible solution.
