Cossy Ransomware

If you were hit by Cossy Ransomware, it is very likely that Russian is your native language. This threat is written in Russian, and it is unlikely that it would be used to target those who don’t understand it. Our research team informs that the infection was coded in C++, and its launcher could be spread using spam emails, vulnerability exploits, or other infections. Without a doubt, if other threats are involved in the execution of the file-encrypting ransomware, you need to find and delete them as soon as possible. A legitimate malware scanner can help you uncover threats that might be hidden from you. As for the removal of Cossy Ransomware, that is what we discuss in this article. Whether you need to erase this threat or secure your operating system against it, our research team is ready to provide you with the information you need.

Just like many other threats (e.g., Matrix-NEWRAR Ransomware, CryptoNar Ransomware, and Everbe 2.0 Ransomware), Cossy Ransomware encrypts files using the RSA-2048 encryption algorithm. It is complex enough that legitimate file decryptors cannot crack it. Therefore, if your files were encrypted, you truly are in the mercy of cyber criminals. Unfortunately, trusting them to restore your files is more than a bad idea. That is because they are unlikely to help you restore files regardless of what you do. Of course, some victims of Cossy Ransomware might be willing to take the risk because this infection encrypts files everywhere, except for where system files are (%WINDIR%, %PROGRAMFILES%, and %PROGRAMFILES(x86)%). If you are not sure which files were encrypted, all you have to do is check for the “.Защищено RSA-2048” extension attached to the original names. Have you removed the extension, but the file remained unreadable? Well, that is only natural, considering that the ransomware changes files’ data, and the added extension is nothing but an accessory.

Besides encrypting files, Cossy Ransomware also creates a few. One of them is called “Крайне важная инфа.RSA-2048 файл,” and it is the file that the infection is supposed to send to the attacker because it stores the RSA key. The second one is called “Как все эту шалашкину контору расшифровать.txt,” and it is the file that represents the message from cyber attackers. This message is sort of all over the place, but the main point is clear, and that is that victims must pay a ransom and send an email. According to the message, if you email grafimatriux72224733@protonmail.com and then pay a ransom of 50 rubles in Bitcoin, you would get a decoder that would decrypt files. 50 rubles is such a small ransom that we do not even think that Cossy Ransomware is a real threat. In most cases, attackers demand hundreds and thousands of dollars. All in all, even if the ransom note is small, you have to think if paying it is worth the risk. After all, if you contact cyber criminals, they will definitely record your email address, and they might even ask you a bigger ransom or send you malicious files and software. Of course, even if you pay the ransom, you must delete the malicious infection.

We have a manual removal guide that you can use to delete Cossy Ransomware. As you can see, the first step requires you to find and delete the main launcher file. Unfortunately, we cannot guide you to it because it could have been dropped to any folder, and the name could be misguiding too. If you do not think you can make the distinction between malicious and harmless files, manual removal might not be for you. We suggest you get yourself an anti-malware program. Do not be afraid to invest in your virtual security, because that is the investment worth making. Just don’t forget to update your software to ensure that you are protected fully and efficiently. We also need to talk about files. Although the ones corrupted by Cossy Ransomware are unlikely to be salvageable, from now on, back up your files. If copies exist, you will not lose files even if malware finds its way in.

Cossy Ransomware Removal

1. Delete the malicious [random name].exe file that is the launcher.
2. Delete the file named Как все эту шалашкину контору расшифровать.txt.
3. Delete the file named Крайне важная инфа.RSA-2048 файл.
4. Empty Recycle Bin to fully eliminate these files.
5. Run a full system scan to make sure no malicious leftovers exist.
