Any files that are encrypted with Cerber v4x/v5x
will be renamed (encrypted) with 10 random characters followed by a random 4 character
hexadecimal extension appended to the end of the encrypted data filename (i.e. 1xQHJgozZM.b71c
) and leave files (ransom notes) named README.hta, README.html, _HEJDDP_README_.hta as explained here
. Any files that are encrypted with Cerber v5x
will also include a few new changes as explained here
You can submit samples of encrypted files and ransom notes to ID Ransomware
for assistance with identification
. This is a service that helps identify what ransomware may have encrypted your files and then attempts to direct you to an appropriate support topic where you can seek further assistance. Uploading both encrypted files and ransom notes together provides a more positive match and helps to avoid false detections.
Unfortunately, there is still no known way
to decrypt files encrypted by Cerber v2/v3 or newer v4x/v5x
variants which use 10 random characters with a random 4 character (i.e. .b71c
) hexadecimal 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.
When or if a solution is found, that information will be provided in this support topic and you will receive notification if subscribed to it. In addition, a news article most likely will be posted on the BleepingComputer front page
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.
