We are searching for days for any solutions. (Here, Bleepingcomputer, Google in general,..)
Everywhere we get the same answer. The ransomware ist still under investigation.
(e.g. https://www.bleepingcomputer.com/forums/t/698566/jamper-buran-ransomware-your-files-are-encrypted-txt-support/)
Is there any chance of getting the files back?

I would believe it uses a form of RSA encryption, which requires knowledge of a private key in order to decrypt files (files are encrypted with a public key, which can be analyzed without revealing anything that could aid in decryption). The private key is usually kept safe on the servers operated by the criminals, and it's fairly common for ransomware to generate a new private key for each computer.

In addition, Buran was launched as a project that can be bought and remade in order to complicate the detection by antiviruses, transfer data to the server, and key the key in a secure way that cannot be obtained otherwise.

We have already seen several projects redone from the original Buran.

Service ID Ransomware identifies everything under one name, so only a specialist can find the differences.
