Customer called and found all of their file names changed with a file extension of a79a. Each folder contains all of the encrypted files and two files _HELP_HELP_HELP_5M6C2B8.jpg (instructions) & _HELP_HELP_HELP_5M6C2B8.hta. I've attempted to identify the ransomware using https://id-ransomware.malwarehunterteam.com/ but no success. Also reviewed the list of ransomware topic infections here: http://www.bleepingcomputer.com/forums/t/608773/list-of-ransomware-support-topics-faqs-and-news-articles/ with no luck. I cleaned the malware with bitdefender rescue disk then booting into safe mode and running malwarebytes antimalware, adwcleaner, hitmanpro. This is the first time I've seen this variant so I'm hoping someone can help identify.

I do not see any submissions to ID Ransomware by that filename. Are you sure you uploaded the ransom note without tampering with the filename? ID Ransomware would have told you it is Cerber 5.0. There is no way to decrypt the files, you can only restore from backups.

Thanks for the reply and the ID Demonslay335. I did upload them last night around 9PM EST and was given the message that it didn't know what encryption it was. this was my first time using the service (which is awesome btw) so I may have done something incorrect.

There is an ongoing discussion in this topic where you can post any more 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 that 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.

Thanks
