not sure you can get hold of the legitimate decryption keys without paying the ransom. There's some information on here that may help but by the look of it attempts to break the encryption may result in a loss of the files altogether:

Hi,

I don't think there is decrypter for version 3. There was for earlier version.

You can follow up news regarding ransomware and decrypting tools on following link, so maybe there will be some tool available soon..

It was mentioned in the past of Trend Micro Ransomware File Decryptor, that can decrypt files encrypted by Cerber. But for the variants there are no further decryptor. You may still attempt but do have a backup to test. Safest is still to recover data from your past latest backup, this is best effort.

Also note the Trend Micro caveats
CERBER Decryption Limitations
CERBER decryption must be executed on the infected machine itself (as opposed to another machine) since the tool needs to try and locate the first infected file for a critical decryption calculation.

Due to the method of decryption for CERBER, the tool may take several hours (average is 4) to complete decryption on a standard Intel i5 dual-core machine.   In addition, the encryption logic for CERBER also is built in such a way that the more cores a CPU has, the lower percentage chance of success for the decryption because of its complexity.

Similar to some other types of ransomware encryption, some files may be only partially decrypted and may require a subsequent file repair.

Without decryption key and backup, the original  files will not be recoverable.
