When Kuus Ransomware attacks, it slaps on the “.kuus” extension to the files that it corrupts. These could be documents that are needed for work or school, or photos of your last birthday celebration. It seems that this malware can successfully encrypt all of the personal files that you own, and losing them could be extremely painful. Whether the encrypted files have the additional extension or not, you cannot read them normally. That is because the data of these files is scrambled to ensure that they can be read only with a special decryptor. The attackers behind the threat hope that all victims need this decryptor because only if a need for a decryptor exists can they continue with their attack. Hopefully, you know better than to trust cybercriminals, and you know very well that deleting Kuus Ransomware is the goal. We have information that, hopefully, will help you remove the infection successfully, and we also share our insight into how this malware works. If you are curious, keep reading.
You might not know this yet, but Kuus Ransomware is part of a large family of malware. It is known as the STOP Ransomware family, and the name comes from the first infection that is associated with it. Some of the more recent versions of this malware include Maas Ransomware, Sqpc Ransomware, and Kiratos Ransomware. Every variant has a unique name, but they are pretty much identical. Some of them use unique contact details. Others use the same details, which confirms that the same attackers control at least one portion of these STOP Ransomware variants. Just like its predecessors, Kuus Ransomware is most likely to enter Windows systems with the help of vulnerabilities, downloaders, spam emails, and other threats. In the future, after you delete the threat, you need to keep in mind that opening spam emails (especially files and links attached to them) or downloading files from unfamiliar sources can be extremely dangerous. If cybercriminals trick you into executing a malicious launcher file, you might not even notice when all of your personal files get encrypted.
Even before you discover that your files cannot be read and that the “.kuus” extension is appended to their names, you might face a file named “_readme.txt.” It opens a window with a message, according to which, all personal files were encrypted and can be decrypted only if a special decryption tool and key are employed. The price for the tool and the key is $980, but you are offered a 50% discount. This is just a trick, and you do not want to pay any attention to the message. Is it a good idea to email the attackers behind Kuus Ransomware (at firstname.lastname@example.org or email@example.com) just to see what they want? It is not, because you do not want to give them the power to flood you with misleading, scary, and malicious emails now or in the future. So, if contacting the attackers and paying the ransom is not a good idea, what can you do? Hopefully, you can replace all files with backup copies that you have stored on an external drive or online. Or you can successfully employ the free STOP Decryptor. If you are interested in using this tool, be aware that it does not guarantee full decryption, and also watch out for fake dupes.
Our research team strongly recommends implementing anti-malware software for the removal of Kuus Ransomware. Not only can this software automatically remove all malware components – and remember that other threats could exist as well – but also reinstate Windows security and ensure protection in the future. Note that if you delete Kuus Ransomware yourself, that will not make your system much more secure than it was before the attack. You could confront a new kind of infection sooner than you think, and it is up to you to ensure that that does not happen. First and foremost, secure your system. As we have made it clear, we suggest using anti-malware software for that. Second, secure your files. Overall protection is not enough, and you should always store backup copies somewhere safe. Finally, look at your own habits to see where you can improve. For example, if you have the habit of visiting unreliable websites, you have to break it. Keep this in mind, and you will stay away from malware in the future.
