What is Kuub Ransomware?
Ransomware applications are still prevalent as we encounter them every day. In this report, we discuss another Stop Ransomware’s new version that is called Kuub Ransomware. Just like the clones created before it, the malware received its name from the extension it adds to its encrypted files, which is called .kuub. If you see this extension on your data, you probably infected your system with this malicious application. If you want to know how it might have happened and what to do to void threats alike, we recommend reading our full article. In it, we discuss the malware’s effective manner and its deletion as well. Plus, you can find step by step removal instructions ta the end of this article that show how to eliminate Kuub Ransomware manually.
Where does Kuub Ransomware come from?
Usually, threats like Kuub Ransomware travel with infected email attachments. You might think you would recognize if a file was infected or malicious, but, in reality, it might be much more difficult. Data carrying such malware does not necessarily have to be or look like an executable file. Instead, the malicious launchers could look like text documents, pictures, and other harmless data. Unfortunately, it might be enough to launch such a file to get your system infected and your files encrypted.
Some malicious launchers can look like Microsoft Word documents after being launched. However, they often show warnings saying it is imposing to view their content and that a user has to click the Enable Content button. Sadly, in cases like this, such interaction with a malicious document might initiate malicious scripts that could drop a ransomware application on a system. Thus, to avoid such threats, users must be careful with all files from unreliable sources and unexpected attachments. A legitimate antimalware tool might be most useful in such cases as with it, you could scan suspicious files and find out whether they are infected or not.
How does Kuub Ransomware work?
Kuub Ransomware should create a randomly named folder in the %LOCALAPPDATA% directory. This folder may contain the threat’s launcher’s copy and other files it might need. Next, the malicious application should start encrypting pictures, photos, text and other types of documents, archives, and other private data. The threat should not encrypt any files belonging to an infected computer’s operating system. Other program files should not be affected either. The reason cybercriminals behind such malware often targeted personal data is because they know that many users do not back up their data and will not be able to restore it if anything happens.
After encrypting files, Kuub Ransomware should open a text document containing a particular message. It should explain that only the malware creators can decrypt files and that a user would have to pay to receive deception tools. Like with any threats from Stop Ransomware family, the note claims the price is 980 US dollars, but if a user pays within 72 hours, he gets a 50 percent discount, which turns the ransom into 490 US dollars. Keep in mind that despite the hackers’ promises, there are no guarantees they will hold on to their end of the bargain and that if you pay this sum, you could lose it in vain.
