.aes_ni_0day AES-NI File Virus – Restore Files (Update April 2017)

Article created to help you remove the special version of the AES-NI ransomware virus, called NSA EXPLPOIT EDITION and restore .aes_ni_0day files.

A new variant of the AES-NI ransomware infection has come out in the wild. The ransomware uses multiple evasion tactics to infect and encrypt the files on the computers infected by it. The virus then drops a ransom note file, named !!! READ THIS – IMPORTANT !!!.txt in which demands are made to purchase the decryption keys at a high price. In case you have become a victim of the new version of AES-NI ransomware, recommendations are to read this article and follow it’s instructions and steps.

AES-NI Ransomware – Infection Process

Infection via AES-NI ransomware’s special edition is conducted in a very similar manner to the infection process of the older version. The ransomware may still utilize infection techniques that include sending fake e-mails that contain malicious e-mail attachments. These e-mails may contain different types of files added as attachments:

  • VBS script file.
  • JavaScript files.
  • Files that are executable (.exe).
  • Files that are Microsoft Office or Adobe .pdf documents and have malicious macros embedded within them.

The content of the spam messages is usually of a deceptive nature, meaning that they pretend to be legitimate notifications of a purchase, invoice, complaint or some important topic, to convince victims into opening the malicious attachments or clicking on the malicious link posted. Example of such e-mails can be seen below:

Besides e-mail, cyber-criminals who are behind the AES-NI infection may authorize themselves to upload malicious files on file-sharing websites, like torrent sites, for example. Such files may be presented to the user as key generators to activate a license for a given program or a crack or patch for different software.

In addition to those methods of infection, other methods may include the usage of fake updates, fake installers or game patches, software license activators and even fake key generators, all of which may be uploaded on various websites.

Once the user’s computer becomes infected via one of the above mentioned ways, the AES-NI ransomware drops It’s payload. It consists of the following types of files:

  • !!! READ THIS – IMPORTANT !!!.txt
  • .key.aes_ni_0day files
  • Exectuable files located in the %System Drive%, %AppData% or %Windows% folders.

.Aes_ni_0day File Virus – Infection Activity

The new version of the AES-NI ransomware may begin to tamper with the Windows Registry by adding custom value strings with data in them to run the malicious executables of the AES-NI ransomware on system start up. For this, the following keys may be targeted:

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce

Other activity of the AES-NI ransomware includes a check which the virus makes that returns information whether or not the infected computer is from the former Soviet Union countries. If so, the ransomware infection begins switch off and self-deletes after this.

But this is not all of the activity of the AES-NI infection. If the virus continues being active, it will inject a malicious code into the svchost.exe Windows process. After this, the virus may run an obfuscated command via Windows Command prompt that deletes the shadow volume copies on the infected computer:

→ process call create “cmd.exe /c
vssadmin.exe delete shadows /all /quiet
bcdedit.exe /set {default} recoveryenabled no
bcdedit.exe /set {default} bootstatuspolicy ignoreallfailures

The Encryption Process of .aes_ni_0day Virus

For the encryption, AES-NI targets the following files:

  • Documents.
  • Music.
  • Videos.
  • Recordings.
  • Images.
  • Database files.

The virus is careful to skip system or executable files of the following format, since they may damage the operating system:

.dll, .exe, .lnk, .mui, .sys

The encryption process of the virus is conducted in what is known in the trade as ECB mode. It applies an AES – 256 encryption cipher on the files, replacing blocks of data with data from the cipher. Once this is done, asymmetric key is generated and sent to the cyber-criminals who are behind the ransomware operation. In addition to the AES keys, RSA keys are also appended on each file or set of files and they are unique for each of them. These keys are also sent to the crooks. The generated keys are in files, ending with .key.aes_ni_0day.

After encryption by AES-NI’s special version has been completed, the virus adds the suffix .aes_ni_0day and the files no longer appear the same:

Then, AES-NI may open the !!! READ THIS – IMPORTANT !!!.txt note which has the following ransom demands:

AES-NI FAQ

What is AES-NI ransomware and how does it work?

AES-NI is a ransomware infection - the malicious software that enters your computer silently and blocks either access to the computer itself or encrypt your files.

Many ransomware viruses use sophisticated encryption algorithm how to make your files inaccessible. The goal of ransomware infections is to demand that you pay a ransom payment to get access to your files back.

How does AES-NI ransomware infect my computer?

Via several ways.AES-NI Ransomware infects computers by being sent via phishing e-mails, containing virus attachment.

This attachment is usually masked as an important document, like an invoice, bank document or even a plane ticket and it looks very convincing to users.

After you download and execute this attachment, a drive-by download occurs and your computer is infected with the ransomware virus.

Another way, you may become a victim of AES-NI is if you download a fake installer, crack or patch from a low reputation website or if you click on a virus link. Many users report getting a ransomware infection by downloading torrents.

How to open .AES-NI files?

You can't. At this point the .AES-NI files are encrypted. You can only open them once they are decrypted.

Decryptor did not decrypt my data. What now?

Do not panic and backup the files. If a decryptor did not decrypt your .AES-NI files successfully, then do not despair, because this virus is still new.

One way to restore files, encrypted by AES-NI ransomware is to use a decryptor for it. But since it's a new virus, advised that the decryption keys for it may not be out yet and available to the public. We will update this article and keep you posted as soon as this decryptor is released.

How Do I restore ".AES-NI" files (Other Methods)?

Yes, sometimes files can be restored. We have suggested several file recovery methods that could work if you want to restore .AES-NI files.

These methods are in no way 100% guarantee that you will be able to get your files back. But if you have a backup, your chances of success are much greater.
