Hello VirusD, my files were encrypted by  Cerber ransomware and the extension of files is .8efe
You can help me decrypt them. Thank you very much Alejandro.

Any files that are encrypted with Cerber v4x/v5x will be renamed (encrypted) with 10 random characters followed by a random 4 character extension appended to the end of the encrypted data filename (i.e. 1xQHJgozZM.b71c) and leave files (ransom notes) named README.hta as explained here. Any files that are encrypted with Cerber v5x will also include the following changes as explained here.

* The ransomware will now skip 640 bytes, compared to 512 bytes in previous versions, when encrypting a file.
* The minimum file size that Cerber will encrypt a file is now 2,560 bytes, compared to 1,024 bytes in previous versions. This means that any file that is smaller than 2,560 bytes will not be encrypted.


Unfortunately, there is still no known way to decrypt files encrypted by Cerber v2/v3 or newer v4x/v5x which uses 10 random characters with a random 4 character (i.e. .b71c) extension without paying the ransom.

There is an ongoing discussion in this topic where you can post comments, ask questions and seek further assistance. Other victims have been directed there to share information, experiences and suggestions.

Rather than have everyone with individual topics, it would be best (and more manageable for staff) if you posted any more questions, comments or requests for assistance in the above support topic discussion...it includes experiences by experts, a variety of IT consultants, end users and company reps who have been affected by ransomware infections. To avoid unnecessary confusion, this topic is closed.

Thanks
