Vortex Ransomware Infection: Decrypting AES-encrypted Files, One-time Code & Recovery Solutions

Hello dear company.

Short description of the problem:
just after 8 a.m. there was an infection with "Vortex Ransomware" garbage
Has anyone encountered this and found a reasonable solution to decrypt your files.

I have read the basics:
https://sensorstechforum.com/vortex-ransomware-remove-restore-aes-files/
https://www.bleepingcomputer.com/news/securit...-polski-vortex-flotera-ransomware-connection/

At the moment, a 1: 1 backup from the linucha is taking place in order not to work on the infected medium.
Any attempts that I am going to make will also be made in an isolated environment.

I found a one-time code in the virus logs
I will try to decode the files with this https://github.com/EslaMx7/AESxWin/releases because the virus uses this mechanism.
If the files cannot be decrypted, I will try to recover the deleted originals with the recovery software.

I will describe progress or lack of progress - if anyone knows anything about the problem, help is very needed.
A customer without databases may close the company. Of course, backups were not performed, because why ...

I will accept any help. Thank you in advance.

The data was too important. The client paid the ransom.
The group is at least honorable enough. They sent a program that I already had and a key that I couldn't have. Decryption is in progress.

If nobody wants to say anything - the topic is to be closed.
