I think step 1 is to identify the ransomware strain. In this case it seems to be Rapid Ransomware (or some variant of it) based on the file extension and the note.
Does anyone know of a good company that can decrypt those files potentially? It’s quite critical…
I think you’re barking up the wrong tree. There seems to be a lot of information sharing within the community in the fight against ransomware, and if a decryption tool would exist, I think it would be freely available.
A quick Google search seems to suggest that there is no known weakness in the crypto of this particular ransomware.
Please note also that it is entirely possible using strong crypto to encrypt a file in a way that there is no feasible method to decrypt it using any known technology.
At this point I would channel my resources into other recovery methods.
Sorry for the bad news.
(Please do double check that there really isn’t any know weakness and that this really is Rapid Ransomware. https://www.nomoreransom.org/en/decryption-tools.html is a good resource, backed by some big anti-virus companies).
