Kuub Ransomware

Kuub Ransomware is the infection responsible for adding the “.kuub” extension to your personal files. Unfortunately, this infection does more than just rename them. It also encrypts your files, which means that they cannot be read. The data of your files is changed, and that is done so that you would look for a decryptor, which, conveniently, the attackers offer you right away. The intentions are clear, and it is up to you to decide what should be done. Our research team warns that the attackers can promise you anything just to get you to pay a ransom, and that is why we do not believe that you would be provided with a decryptor if you did as instructed. Needless to say, we do NOT recommend paying the ransom. Of course, you do not need to trust our word. Continue reading this report, and you will be able to make up your own mind. If it is already made up, and your main goal is to remove Kuub Ransomware, you can scroll down to the last paragraph in the report, in which we talk about removal in detail.

The origin of malware is always very interesting and very important. Our research team has found that Kuub Ransomware is part of the STOP Ransomware family and that it is identical to Seto Ransomware, Kvag Ransomware, Zatrov Ransomware, Moka Ransomware, and hundreds of other file-encrypting threats alike. Evidently, these infections were created by the same attackers because once files are encrypted, a file named “_readme.txt” is dropped, and the information within this file has been seen many times before by our team. At the bottom of the message, you are introduced to two email addresses – gorentos@bitmessage.ch and gerentosrestore@firemail.cc – that have been introduced to the victims of other clone infections. Clearly, different attackers would not use the same email accounts to communicate with victims, and that is why we conclude that we are dealing with the same attacker or group of attackers. Unfortunately, this information does not really help much with the removal of the infection or the decryption of your personal files.

According to our malware research team, if the files on your operating system were encrypted using an offline key, you have a chance of getting them back with the help of a free decryptor created by malware researchers. Be careful when installing this tool because fake lookalikes could have been created to fool you. Unfortunately, if you cannot use the tool, or if you do not know about its existence at all, you might think that the option offered by the attackers is legitimate. The message in the .TXT file informs that every victim can get their files back with a special decryption tool that costs $980 (or $490 if paid within 72 hours). The attackers behind Kuub Ransomware know that you might not have other options, and that is why the ransom is so big. Of course, if your files are valuable, but you do not have backup copies that could replace them, you might consider that the sum is not so big. Well, even if you can pay the ransom, what are the guarantees that you would get the decryptor? There are no guarantees, and that is why we suggest that you figure out how to delete Kuub Ransomware instead of figuring out how to pay the ransom.

You should be able to remove Kuub Ransomware manually if you can fulfill one condition. That condition is to find the file that executed the malicious file-encryptor. If you cannot find and erase this file, it could be used to reinfect your operating system, and so it is the most important part of the entire removal process. The bad news is that the name and location of this file are random, and so we cannot help you find it. The good news is that you do not need to delete Kuub Ransomware yourself. You can employ a legitimate anti-malware program to do it for you. Once the malware occupying your system is automatically deleted, the program can continue protecting you, and that is extremely important if you want to keep your system malware-free in the future. You also need to take care of your files. Hopefully, you can restore the files corrupted by the malicious ransomware, but if you cannot, we hope that you have backup copies stored someplace safe. In the future, ALWAYS backup all of your personal and sensitive files.
