AES-Matrix ransomware attempts to convince companies to pay a ransom because it is “not a shame”

AES-Matrix virus

AES-Matrix ransomware is a newly discovered computer virus that corrupts files[1] on victim’s computer but adds no extensions to encrypted files. Consequently, the malicious program composes a ransom note and saves it in folders with encrypted data. The ransom note suggests contacting criminals via darkpart@tutanota.com or darkware@tutanota.com to get help regarding data recovery.

AES-Matrix virus applies AES-256 cryptography[2] to corrupt victim’s files on the target system. It renders documents, images, videos and other valuable files useless by changing their structure. The encryption process can be reversed, but only with the help of a decryption key, which is securely stored in criminals’ servers. There is no way to get it from there. The full message of the ransom note is provided below.

Hello,
Your all datas have been encrypted by AES-256 key,
If you want to decrypt by yourself, It would take hundred years,
If you can pay some money, I will send you the decrypt key, you can get your data back immediately.
According to the CyberEdge Group's 2017 Cyberthreat Defense Report, 1/3 company paid a ransom.
So it is not a shame to pay the ransom, many companies paid it before.
Your are so large […] company.
Now would you like to see your business become a startup or just pay to continue your business?
Contact my email: darkpart@tutanota.com or darkware@tutanota.com
If you do not contact me soon, you key will be deleted automatically by system and you will lose your data 4ever.
Just take it as security consultant fee. They charge much more than me.

The cyber criminals want to convince you that there is no way to decrypt the corrupted data; however, that is not entirely true. You can retrieve your files from a backup or use one of data recovery solutions we provided below the article.

Considering that the virus uses AES encryption only, there is a reason to believe that malware analysts might find a way to decrypt files, especially if the ransomware authors left some mistakes in their code. However, this can still take ages. In the meanwhile, we recommend you to remove AES-Matrix malware.

It is important to eliminate the virus from your computer before trying to use any data recovery methods. You can obliterate the malware from the system using AES-Matrix removal guidances we provided; however, you will still need a decent anti-malware in order to complete the system cleanup. Please remember that ransomware is no regular software and it can’t be uninstalled that easily. In addition, DieViren.de experts[3] point out that this ransomware ISN'T related to Matrix ransomware.

Ransomware distribution peculiarities explained

AESMatrix virus reportedly infiltrates the computer system or network via Remote Desktop Connection (RDP) attacks. RDP allows users to log into a particular Windows computer remotely via RDP client and use the system as if it was local.

  • To protect your company from such attacks, use strong passwords (including at least eight characters, upper/lower case letters and digits or symbols) for all accounts but especially for those with Admin’s rights;
  • Set your system to block a specific user for a certain period after repetitious unsuccessful attempts to log in. This way, you could interfere the brute-force attack and prevent the attacker from guessing the password that quickly and easily.
  • Require two-factor authentication.

Finally, ransomware uses a lot of other techniques to infiltrate systems, for instance, deceptive emails or malvertising. For this reason, we recommend you to enable automatic software updates, stay away from suspicious emails (even if the sender tries to convince you to open an attached resume or an invoice) and protect the entire computer system/network with a decent anti-malware software.

Remove AES-Matrix virus and unlock your files

There is a certain order of tasks you need to complete to remove AES-Matrix virus from your computer or the whole computer network. Firstly, you need to reboot your computer and start it in Safe Mode with Networking regime. This will prevent the malicious processes from starting and allow you to remove the malware without running into unpredicted obstacles.

AES-Matrix removal is required to make the computer appropriate for further use. The automatic spyware/malware tool is recommended because it will delete all of the malicious or potentially unwanted files and programs from the system with ease.

Bonus: Recover your data

Guide which is presented above is supposed to help you remove AES-Matrix from your computer. To recover your encrypted files, we recommend using a detailed guide prepared by 2-spyware.com security experts.

Use a data backup to restore files that were corrupted by the AES-Matrix malware. In case you forgot to create a data backup in the past, at the moment all you can do is to try the alternative data recovery options we listed below.

If your files are encrypted by AES-Matrix, you can use several methods to restore them:

Run Data Recovery Pro

Run Data Recovery Pro software to find the compromised files and attempt to restore them. Remember that the software might not be able to recover them – the virus uses a highly sophisticated algorithm to prevent you from using them again.

Examine your computer with ShadowExplorer

We suggest that you check your system with a special tool known as ShadowExplorer. It will help to find and recover files using Volume Shadow Copies. The problem is, many ransomware viruses delete these copies after encrypting the original files.

  • Download Shadow Explorer (http://shadowexplorer.com/);
  • Follow a Shadow Explorer Setup Wizard and install this application on your computer;
  • Launch the program and go through the drop down menu on the top left corner to select the disk of your encrypted data. Check what folders are there;
  • Right-click on the folder you want to restore and select “Export”. You can also select where you want it to be stored.

AES-Matrix decryptor

AES-256.exe is reportedly the decrypter sold by the cyber criminals. However, so far it seems that it doesn't work quite well. That is yet another reason not to pay the ransom!

Finally, you should always think about the protection of crypto-ransomwares. In order to protect your computer from AES-Matrix and other ransomwares, use a reputable anti-spyware, such as Reimage, Plumbytes Anti-MalwareWebroot SecureAnywhere AntiVirus or Malwarebytes Anti Malware
