removal by Alice Woods - - | Type: Ransomware

ARTEMY ransomware is a file locking malware that targets Russian users

ARTEMY ransomware
ARTEMY ransomware is a file locking virus that comes from Scarab family

ARTEMY ransomware is a data locker that was first spotted by the security researcher Amigo-A at the end of February 2019. It comes from Scarab virus family and targets Russian-speaking users, similarly to other variants like Scarabey, Osk, and Bomber. The cyber threat uses the AES encryption algorithm to lock up documents, databases, pictures, music, videos, etc. and appends .ARTEMY extension and scrambles names of data, consequently preventing victims from opening any files that are modified that way. Scarab-Artemy virus then generates a ransom note КАК ВОССТАНОВИТЬ ЗАШИФРОВАННЫЕ ФАЙЛЫ.TXT (“how to recover encrypted files.txt”), which explains to users how to proceed next. Allegedly, the decryption key can be purchased for an undetermined amount of Bitcoin, after contacting cybercriminals via emails artemy75@protonmail.com, artemy75@cock.li, or artemy75@tutanota.com. According to researchers, discounts up to 80% are offered to pregnant women, the unemployed, the disabled, and the poor. However, paying ransom is not recommended in any case – victims should remove ARTEMY ransomware and use alternative file recovery methods.

Distribution Malicious spam emails, fake updates, weak RDP, etc.
Elimination Use anti-malware applications like Reimage, Malwarebytes MalwarebytesCombo Cleaner, or any other software that can recognize the infection[1]

ARTEMY ransomware is most likely distributed with the help of malicious phishing emails, repacked installers, unprotected RDP configuration, fake updates, torrent files, or similar methods. To stop the infection before it locks data, you should always keep a security application running in the background. For additional defense methods against Scarab-ARTEMY, check the second section of the article.

Once ARTEMY virus is extracted on the host device, it performs various changes to it, such as:

  • Disables Windows auto-repair function at the startup;
  • Removes Shadow volume snapshots;
  • Creates and modifies Windows Registry[2] keys;
  • Opens MountPointManager;
  • Spawns and kills many processes, etc.

Once system modification is complete, ARTEMY ransomware begins file encryption procedure and drops the ransom note to the affected folders. The files are modified by using the encryption algorithm; for example, picture.jpg is turned into BUXjzYpCJ7O5zQH2s19jyqLbr.ARTEMY. This process consequently prevents users from accessing any data – only the decryption tool would be able to decode it.

Allegedly, ARTEMY ransomware authors claim that unemployment made them engage in this illegal business. Whether it is true or not is a different matter, but it does not change the fact that what these people are doing is money extortion – it is highly illegal and harmful to innocent users. Additionally, according to the ransom note, the offered discounts can only be applied once legal documents are provided.

Do not send any type of documents that confirm your identity – the sensitive information can be stolen and sold on the black market for profit. Instead, focus on ARTEMY ransomware removal. For that, you will have to employ anti-virus software that is capable of recognizing[1] the threat. We recommend using Reimage or Malwarebytes MalwarebytesCombo Cleaner

Avoid ransomware viruses by using precautionary measures

Ransomware developers usually take advantage of several malware distribution methods, such as spam emails, malicious executables hosted on hacked sites, brute-force attacks, botnets, and other techniques. Therefore, getting infected with ransomware might be easier than one might think.

You should never ignore security tips from industry experts:[3]

  • Download and install a reputable security application;
  • Enable Firewall;
  • Always patch your system with the latest security updates;
  • Do not click anything on suspicious websites;
  • Avoid high-risk sites, such as porn, gambling, torrent, etc.
  • Scan all executable files or suspicious URLs with tools like Virus Total;
  • Use ad-block (don't forget to use exclusions for sites you want to support);
  • Beware of spam email attachments and hyperlinks inside.

Terminate ARTEMY ransomware virus infection based on our instructions

Without a doubt, you should remove ARTEMY ransomware as soon as possible and never contact cybercriminals. For that you will need to employ reputable security application, such as Reimage or Malwarebytes MalwarebytesCombo Cleaner – these tools recognize the threat as TR/AD.ZardRansom.grojy and Ransom.Scarab. Be aware, however, that ARTEMY virus might hinder proper elimination procedure. In such a case, enter Safe Mode with Networking and scan your device from there. 

Once you complete ARTEMY ransomware removal, you can proceed with the file recovery process. To recover data, you need a specific decryption key that is stored on a remote server, only accessible to criminals. Nevertheless, you can always return all your files if you store backups on a remote server (such as OneDrive) or an external device.

If you do not have backups ready (most people do not), you can take advantage of third-party solutions that might help you; you will find download links and instructions on how to use them below. Remember, paying crooks might result in money loss, so do not risk it.

Bonus: Recover your data

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

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

Try Data Recovery Pro for file return

This application is originally designed to retrieve files that were accidentally deleted or corrupted, but users found that it can recover data locked by ransomware in some cases.

  • Download Data Recovery Pro;
  • Follow the steps of Data Recovery Setup and install the program on your computer;
  • Launch it and scan your computer for files encrypted by ARTEMY ransomware;
  • Restore them.

Make use of Windows Previous Versions feature

If you had System Restore enabled before the virus attack, use Windows Previous Versions feature to retrieve separate files.

  • Find an encrypted file you need to restore and right-click on it;
  • Select “Properties” and go to “Previous versions” tab;
  • Here, check each of available copies of the file in “Folder versions”. You should select the version you want to recover and click “Restore”.

ShadowExplorer might be able to recover all your data

While Scarab-ARTEMY ransomware tries to remove Shadow Volume Copies, it might fail to do so. In such a case, use Shadow Explorer to recover your 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.

No decryption tool is currently available

Finally, you should always think about the protection of crypto-ransomwares. In order to protect your computer from ARTEMY and other ransomwares, use a reputable anti-spyware, such as Reimage, Malwarebytes MalwarebytesCombo Cleaner or Plumbytes Anti-MalwareMalwarebytes Malwarebytes
