Buran ransomware – a data-locking infection that leaves a “BURAN” file marker

Buran ransomware
Buran ransomware is a file-locking threat which encrypts valuable data and urges users to contact the crooks for further (ransom-related) details

Buran ransomware is a file-encrypting malware form that appends an extension (.3674AD9F-5958-4F2A-5CB7-F0F56A8885EA) of numerous random letters and numbers. The first one to discover Buran virus was Michael Gillespie. He found out that the added appendix looks like a GUID (Globally Unique Identifier),[1] and is added to each encrypted document. Moreover, all files are marked with an identifier “BURAN” which signifies about the dangerous infection. After the data is blocked, a ransom message named !!! YOUR FILES ARE ENCRYPTED !!!.TXT[2] is loaded onto the desktop in order to inform the victims about what just had happened. The criminals urge contact via recovery_server@protonmail.com and recovery1server@cock.li email addresses. In order to discuss all conditions about data restoring, the crooks demand users to send their ID's to both emails and also provide them with an offer of free decryption of from three to five data files that take up no more space than 10 MB.

Buran ransomware is a dangerous threat which no one wants to see on their machines. However, if the cyber threat has already occupied your system, you should be prepared for all possible consequences. Note that, the criminals are capable of modifying various registries entries and tasks by activating remote commands.

This might also allow Buran ransomware to inject other malware straight into the system and cause severe damage to it. If a Trojan horse[3] ends up on your computer, you might find the entire system struggling to carry out even simple actions and launch programs. Moreover, trojans can relate to personal data and identity theft.

If you decide to contact the crooks, they will supposedly offer you a decryption tool for a particular price in order to bring back files that have been locked by Buran ransomware. Such people usually urge for Bitcoin[4] or another type of cryptocurrency which allows the process to remain safe and untrackable by others.

We recommend denying any offers for ransom payments as this might be a scam. You risk losing money are being left by nothing. Rather than contacting these people and wasting your money and time, we recommend performing the Buran ransomware removal from the entire computer system and cleaning all infected directories.

Programs such as Reimage or SpyHunterCombo Cleaner will scan the entire system for potential threats and hazardous content. This will allow you to remove Buran ransomware entirely. Note that it is very important to clean locations such as the Windows Task Manager and Registry as the malicious payload needs to be removed or you will not be able to recover encrypted files.

If you want to be sure that Buran ransomware has been attacking your computer system lately, these type of signs will show you that this malware is the one who has been bothering you and causing you troubles recently:

  • The 3674AD9F-5958-4F2A-5CB7-F0F56A8885EA extension near each file.
  • “BURAN” file marker placed next to locked data.
  • EDILI INDUSTRIA.pdf.3674AD9F-5958-4F2A-5CB7-F0F56A8885EA file in the system.
  • !!! YOUR FILES ARE ENCRYPTED !!!.TXT ransom note.

If you have seen one or more signs from this list, you can be sure that Buran ransomware is active on your machine. Our recommendation would be to react fast and get rid of the malware before it causes other damaging consequences such as additional malware infiltration, system modifications, and runs other malicious processes in the background.

Email spam carries malicious threats 

According to cybersecurity researchers from LosVirus.es website, spam messages are often used for carrying malicious payload. Ransomware-related infections are often spread via email spam and infiltrate users' computers by using stealth techniques. Usually, crooks pretend to be from reputable organizations and urge people to open the attached file for further important information regarding the received email letter.

We urge all users to be very careful while sorting out their email messages. If some letters have fallen straight to the spam section, better get rid of them without even opening as no reliable companies will waste your time by contacting like you in these types of ways. Furthermore, DO NOT open any attached files without scanning them with antimalware if you are not sure that they are safe to download.

Staying cautious on the Internet sphere and avoiding possible risks of malware infection is very important. The more serious you are with your online and computer safety, the better your chances will be for having a clean, optimized, and undamaged computer system. If you want to ensure that reputable protection does not fail you at any time of the day, you should get a strong and reliable antimalware program for this.

Spotting encrypted files is definitely not the most pleasant view to see. However, do not panic and rush to contact the crooks as other ways might be more helpful for data recovery. What you have to do is take a look at the following file restoring techniques and complete each step carefully to reach the best results possible.

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

Use Data Recovery Pro for file recovery:

  • 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 Buran ransomware;
  • Restore them.

Windows Previous Versions feature is suitable for data restoring:

Restoring encrypted files is a difficult process, however, you might still have a chance of returning some of your documents to their previous states. Continue with this method if you have enabled System Restore in the past:

  • 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”.

Shadow Explorer might allow you to return some files back:
