What is Koolova?

Koolova is an in-development ransomware that was discovered recently. As far as ransomware goes, this is a strange one. It’s still being developed which means it’s not fully functional but that could change at any time. If it were to become functional, it would most likely spread via spam emails and fake downloads. Most ransomware encrypt your files and then demand that you pay to get them back. The main goal of Koolova seems to be to educate users about the dangers of ransomware. They do not demand that users pay, they just want you to read two articles about ransomware. Once the user has done that, he/she can decrypt the files. You would then need to delete Koolova.


What would the functioning version of Koolova do?

Even though Koolova is not operational at the moment, we want to take this chance and inform you of possible ways to get infected with other ransomware. The most popular method among cyber criminals is spam email attachments. An infected file is attached to an email and when someone opens it, the virus download onto the computer. Just one click and your computer is infected. This is why it’s important that you be cautious and do not open attachments left and right. Always make sure they are safe before you do. You should also be careful with downloads. Do not download suspicious files from pop-ups and refrain from using Torrents. If you insist, at least take all measures to ensure it’s safe.

Koolova would encrypt your files and then launch a ransom note. The developer is introduced as the ‘nice Jigsaw’, Jigsaw’s twin. He will inform you that your files have been encrypted and that this infection is referred to as ransomware. The developer proceeds to ask victims that they stop downloading unsafe applications. Koolova gives you the option of decrypting files if you read two articles related to staying safe. The two articles mentioned are from Google Security Blog and BleepingComputer, respectively. When the victim finishes reading those two articles, the Decrypt My Files button will be available. The decryptor would then be displayed and once the victim puts in the decryption key, files would be restored. Koolova does not demand any money, it just seems to want to educate people about how dangerous infection could be and how to protect computers from them. Although, it does promise to delete your files if you fail to read the articles in time, which it might be able to do. In any case, Koolova is still in-development and there are much more serious ransomware to worry about.
