I have only encripted files. Id-ransomware can't determine type of ransomware. Extensions are changed to mmvkpbj, I will attach sample file https://www.sendspace.com/file/abr01z .   10x

We will need a ransom note in order to properly identify. A few ransomwares generate a completely random extension, so ID Ransomware cannot properly identify (without generating an obscene amount of false-positives) without a matching ransom note (which is compared with the extension in some cases).


CTB-Locker and Maktub are generally the two most common that create a totally random 6-7 character extension for files. CTB-Locker would typically have a ransom note called "!Decrypt-All-Files-mmvkpbj.txt", and Maktub would have "_DECRYPT_INFO_mmvkpbj.html". Both cannot be decrypted I'm afraid.


Based on infection rates as of late, I'm more suspecting you may be a victim of CTB-Locker. You can view more information in the following topic to see if your symptoms match up.

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. To avoid unnecessary confusion, this topic is closed.
