What is BlackToxic ransomware
BlackToxic is a virus that is based on Chaos ransomware. As with every other ransomware program, BlackToxic exists to make money for the person who created it. This is accomplished via a multi-step process. First, the virus infects the victims’ computers and encrypts all data. Then, the victim is told that they have to pay (typically in cryptocurrency like BitCoin) a certain amount of money to the hacker if they want the data back.
In BlackToxic’s case, the encrypted files are given the “.KsiRu0w2” extension. So if you had a file named “video.mp4”, it will be renamed to “video.mp4.KsiRu0w2”. This will prevent them from being opened in any program, but renaming them back wouldn’t help, as the files are encrypted.
The ransom note is a file called “read_it.txt”, which is placed on the victim’s desktop. The image above contains the text of the note – as you can see, it is very unprofessional, even by hackers’ low standards. It has also been reported that the virus changes the victims’ desktop background – the new background is a modified Razer logo, rendered in red instead of green.
This guide will explain how to remove BlackToxic ransomware and decrypt .KsiRu0w2 files. Sadly, when it comes to the decryption, your options are limited – you may not be able to recover all of your data.Nonetheless, by using the options listed below, you should be able to recover as much as possible.
