Kuus Ransomware

What is Kuus Ransomware?

If your computer cannot open your files and they have .kuus extension, your system might have been infected by a threat called Kuus Ransomware. It is a malicious file-encrypting application that uses a robust encryption algorithm to lock files that could be valuable. Afterward, the malware drops a ransom note asking to pay ransom if you want to get decryption tools that could unlock all files. The hackers may reassure you that you will get the promised tools, but, in reality, there are no guarantees that you will receive them. Therefore, we advise you to think carefully if you really want to deal with cybercriminals. Until you decide that you may want to learn more about the malware, in which case, we invite you to read the rest of this article. A bit below it, you should see our deletion instructions that show how you might be able to erase Kuus Ransomware manually.

Where does Kuus Ransomware come from?

Kuus Ransomware might be spread through unreliable file-sharing websites, malicious email messages, or unsecured RDP (Remote Desktop Protocol) connections. Thus, users could infect their systems accidentally by launching infected software installers, text documents, and other data that could be received or downloaded through unreliable sources. On the other hand, if you are using unsecure RDP connections, hackers could gain access to your system and download and launch the threat’s installer themselves. Therefore, we highly recommend securing RDP connections or disabling them if you do not need to use them. Also, it is advisable not to download files from unreliable file-sharing websites as well as not to launch data received from unknown senders or if it is received unexpectedly. Plus, do not forget that if you want to know if a file is harmless or not, you can always employ a legitimate antimalware tool.

How does Kuus Ransomware work?

As mentioned earlier, Kuus Ransomware is a malicious file-encrypting application, so its main task is to encrypt files that users might be unable to replace, for example, photos, various documents, etc. However, before the threat starts encrypting any files it ought to install itself by creating copies of its launcher. Also, the malware might create a Registry entry and a scheduled task so that it could relaunch itself when you restart your computer. Therefore, leaving the malicious application on your system could be dangerous.

When the encryption starts the malware ought to locate all of its targeted files and start locking them one by one. Thus, bit by bit, all of victims’ personal files should receive the .kuus extension (e.g., flowers.jpg.kuus) and become unreadable. By the time the victim notices anything, the threat might be already done. As you see, it tries to hide itself until it finishes the encryption process. When it is done, Kuus Ransomware ought to show a ransom note in which users ought to be asked to pay ransom. It says that the ransom is $980, but users who contact hackers for further instructions in 72 hours can pay only half of it ($490). The bad news is that you cannot be certain that hackers will keep up with their promises. In other words, you could get scammed.

If you are an experienced user, you could try to delete it manually by following the instructions available below. However, keep in mind that we cannot guarantee that they will work for everyone.
