AES-NI Ransomware

What is AES-NI Ransomware?

AES-NI Ransomware is an infection that encrypts files using an AES encryption algorithm. To decrypt these keys, a special private key is required, but it can only be provided to you by the developer of the ransomware, and, of course, they could care less about your files. Unfortunately, because of that, there is a great possibility that your files will remain permanently encrypted even if you pay the ransom that should help you redeem the decryption key. If your private files are safely backed up on an external drive or online, we suggest focusing on the removal of the ransomware. If your files are not backed up, you probably want to learn more about this infection. If you continue reading, you will learn everything that our malware research team knows about the ransomware. We will also show you how to delete AES-NI Ransomware from your Windows operating system.testtest

How does AES-NI Ransomware work?

RDP brute-force attacks and Doublepulsar backdoors could be used to install AES-NI Ransomware onto your operating system. Other threats could be infiltrated as well. Therefore, when you get to the removal part, make sure you also think about other potentially active infections. The strange thing about this ransomware is that its .exe file is likely to be automatically deleted once the encryption is complete. Needless to say, the encryption process is silent to prevent the victim from stopping it. Unfortunately, in most cases, victims realize that a ransomware has slithered in and encrypted the files only when they see the “.aes_ni_0day” extension attached to their names. The infection also represents itself using a TXT file called “!!! READ THIS - IMPORTANT !!!.txt” and a strange screen-size notification that shows up on startup. At the top of the message, you see words “Microsoft Windows Security Center,” but, of course, Microsoft has nothing to do with it. According to the message, Windows Defender should start scanning your PC for malicious and unwanted software as soon as you click OK. Needless to say, that will not happen. When it comes to that, “!!! READ THIS - IMPORTANT !!!.txt” is much more informative.

The TXT file represented by AES-NI Ransomware suggests that you need to communicate with the creator of the ransomware by emailing,, or What happens if you email them? If you do, they should send you instructions on how to pay the ransom. Should you pay it? First of all, it is possible that you will not be able to pay the ransom due to its size. Second, the chances of getting a decryptor after paying the ransom are extremely slim, and so you have to think if you want to lose money as well? If money is not a problem for you, and you are desperate, go for it, but be warned that your files are most likely to remain encrypted. What about third-party decryption tools that AES-NI Ransomware warns not to use? Needless to say, this warning is bogus, and you certainly should look into this option. Of course, it is unlikely that you will find any legitimate, harmless decryptors that could help, but if you are desperate, you need to exhaust all options. At the end of the day, whether or not your files are restored, you have to make sure that the ransomware is deleted.
