What is Buran ransomware? And how does it work?

Buran ransomware is a file-encrypting virus created to lock important data in a computer. It uses random letters and numbers as its extension in marking the compromised files which seems to be the same as the unique ID given to the victims. This new crypto-virus was discovered by Michael Gillespie and was spotted by a security researcher named “nao_sec” in a malvertising campaign which redirects potential victims to the RIG Exploit kit.

According to security experts, the appendix used by this ransomware looks like a Globally Unique Identifier or GUID and is added to every encrypted file. The instant it infects a targeted machine, Buran ransomware will establish a connection to a remote C&C server controlled by the attackers. This is where it downloads additional components. The downloaded components are then placed on system folders in order to launch and repress system processes. It also employs data gathering module to collect sensitive data in the system as well as the stealth protection module to use the gathered data to evade security and antivirus programs installed in the computer that could interfere with its attack. In addition, it also alters some registry keys and sub-keys like Run and RunOnce so that it can run automatically in every system boot.

After it completes modifying system settings, Buran ransomware will begin encrypting important files in the system using a sophisticated encryption algorithm. Following file encryption, it adds the random characters to every affected file and opens a text file named “!!! YOUR FILES ARE ENCRYPTED !!!.txt” that contains the following message:

“!!! YOUR FILES ARE ENCRYPTED !!!

All your files, documents, photos, databases and other important

files are encrypted.

You are not able to decrypt it by yourself! The only method

of recovering files is to purchase an unique private key.

Only we can give you this key and only we can recover your files.

To be sure we have the decryptor and it works you can send an

email polssh1@protonmail.com and decrypt one file for free. But this

file should be of not valuable!

Do you really want to restore your files?

Write to email polssh1@protonmail.com, polssh@protonmail.com

Your personal ID: –

Attention!

 * Do not rename encrypted files.

* Do not try to decrypt your data using third party software,

it may cause permanent data loss.

* Decryption of your files with the help of third parties may

cause increased price (they add their fee to our) or you can

become a victim of a scam.”
