Ransomware Buran

Buran ransomware is yet another group that has applied the RaaS (Ransomware as a Service) tactic, which is nothing more than outsourcing attacks. The groups that apply this tactic present their malware in forums on the Dark Web in search of buyers willing to carry out attacks.

RaaS expands the scope of ransomware, increasing the number of attacks exponentially. Even though the scope expands, the group avoids attacking certain countries such as Russia, Belarus, and the Ukraine.

Buran is designed to check what the language of the operating system is, if it is from one of these countries, the encryption is not done, but if the encryption has already been started, the group releases the decryption key for free.

The Buran Ransomware is distributed using the Rig Exploit Kit, it breaks into devices through spam e-mails, cracked program download sites. In some cases they send emails with attachments named as important files such as receipts, invoices, and accounts payable.

Buran has the encryption algorithm unknown, however they probably use RSA and AES, which are the most commonly used types in all ransomware.

After encrypting all files on the attacked computer or device, they create a text file (“!!! YOUR FILES ARE ENCRYPTED !!!. TXT”), and place it on the desktop. And they block administrator access, preventing them from changing, saving or editing the files.

In the ransom note the group informs you that the files have been encrypted and that their decryption is only possible with a key that is held by the group on a remote server. This key will only be released when the victim pays the ransom.

It is worth remembering that there is no guarantee that the group will release the decryption key after the ransom is paid, so it is recommended that the victim should look for other solutions, such as backups, in case he/she has not been encrypted, and companies specialized in recovering files encrypted by ransomware, such as Digital Recovery.

Ransomware Recovery FAQ

Every day, ransomware attacks get better and better. After a successful attack attempt, ransomware quickly maps the user’s most important files to begin encryption. Microsoft Office files, databases, PDFs and design are among its main targets.

Ransomware is designed to be unnoticeable, so it can disable all system defenses without being noticed and start the process of encrypting the files. Even though ransomware can go unnoticed by the system, it can still be noticed by the user, because ransomware uses the system’s own resources to do the encryption, this can slow down the system. Ransomware also changes file extensions. So be on the lookout for these signs: System slowdown and extensions being added to files.

Yes, it is possible. You can restart the computer in safe mode which will limit the ransomware’s action as system resources will be locked. You can also disconnect the computer from the Internet which can interrupt the hackers’ connection to your system, it is worth remembering that there is ransomware that works even without being connected to the Internet. You can also start the diagnostics to identify threats with your antivirus, the vast majority of antiviruses have this function.
But there are cases where the encryption was interrupted by the user, some files had already been affected and this caused an error in the encryption and even the hackers could not restore the files, even with the decryption key. In these cases only a data recovery company, such as Digital Recovery, can recover the files.

Yes, attacks usually happen mainly on holidays and weekends during the early morning hours. These days are chosen because there are not many active users on the system, which prevents the attack from being discovered before the encryption is completed.
