What is Tyrant ransomware virus?

Tyrant is a new cyber threat for computer users in Arabic countries

Ransom note by Tyrant ransomware virus

Tyrant is a file-encrypting virus that seems to target Arabic computer users. It encrypts files using AES[1] encryption and runs a ransom note where victims are asked to pay $15 for data recovery. These demands have to be completed within 24 hours time.

According to the research analysis, two executable files – DUMB.exe and locker.exe – are associated with Tyrant virus. As soon as malicious program infiltrates the system, it makes some changes to Windows system and encrypts various targeted files. Then it informs victims about data encryption and asks to pay the ransom.

Malware runs a “Crypto Tyrant” program that presents data recovery instructions which are written in the Persian language. You can read the translated text below:

Your files are encrypted. You have 24 hours to pay a ransom of $15 dollars. Further redemption amount will depend on the period that has elapsed since 24 hours …
The decipherer of the files will be sent after payment is received. If you have any questions, please contact us by email, we will answer you …
Praise be to Allah, and in the Hereafter!

It seems that Crypto Tyrant ransomware aims at the small amount of computer users who live in Iran or other Arabic countries. However, it doesn’t mean that users in Europe or the United States cannot get infected with this crypto-malware.

Even though cyber-criminals demand a small ransom, victims are still not advised to pay it. Even 15 dollars is a motivation for the hackers to continue they illegal work and create more sophisticated infections. Thus, you should focus on Tyrant removal instead of hoping that criminals will keep their promise and provide the decryption software.

In order to remove Tyrant virus, you have to obtain a professional security program and run a full system scan. Our team recommends choosing ReimageIntego for this task. However, you can choose any other software, but don’t forget to update it first to wipe out all malicious content from the device.

The ways how file-encrypting virus spreads

Tyrant, as well as other ransomware-type cyber threats, are most likely to be distributed via malicious spam emails. Typically they include a malicious attachment that is presented as a useful document, invoice or statement. Therefore, users are easily tricked by the safe look of the attachment.

Security experts from the Netherlands[2] warn that people have to be not only vigilant with received emails but also avoid downloading illegal content,[3] software from unreliable sources and stay away from suspicious ads. Malicious programs spread using various techniques, thus it;s important to watch your clicks to avoid ransomware attack.

Additionally, users are advised to install a reputable antivirus program and create backups that will be crucial in case of ransomware infiltration.

Bonus: Recover your data

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

Paying the ransom should not be considered as a data recovery solution. Unfortunately, the official decryptor is not available yet. However, you can try to use third-party software that might help to restore at least some of your files.

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

Try Data Recovery Pro after the Tyrant ransomware virus attack

This professional software is created for restoring accidentally deleted or corrupted files. However, it might help after the ransomware attack too.

  • 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 Tyrant ransomware;
  • Restore them.

Take advantage of Windows Previous Versions feature

If System Restore has been enabled before the ransomware attack, you should follow these steps and copy the most important 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”.

Try ShadowExplorer

If Tyrant did not delete Shadow Volume Copies of the targeted files, you should take advantage of the ShadowExplorer and recover the files with this tool.

  • 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;

How to prevent from getting ransomware

Protect your privacy – employ a VPN

There are several ways how to make your online time more private – you can access an incognito tab. However, there is no secret that even in this mode, you are tracked for advertising purposes. There is a way to add an extra layer of protection and create a completely anonymous web browsing practice with the help of Private Internet Access VPN. This software reroutes traffic through different servers, thus leaving your IP address and geolocation in disguise. Besides, it is based on a strict no-log policy, meaning that no data will be recorded, leaked, and available for both first and third parties. The combination of a secure web browser and Private Internet Access VPN will let you browse the Internet without a feeling of being spied or targeted by criminals. 

No backups? No problem. Use a data recovery tool

If you wonder how data loss can occur, you should not look any further for answers – human errors, malware attacks, hardware failures, power cuts, natural disasters, or even simple negligence. In some cases, lost files are extremely important, and many straight out panic when such an unfortunate course of events happen. Due to this, you should always ensure that you prepare proper data backups on a regular basis.

If you were caught by surprise and did not have any backups to restore your files from, not everything is lost. Data Recovery Pro is one of the leading file recovery solutions you can find on the market – it is likely to restore even lost emails or data located on an external device.
