It is probably a randomly generated extension. No way to identify without a ransom note or the malware itself. I see no filemarkers or anything unique about the encrypted file.

There are several different ransomware infections which append a random 4, 5, 6, 7, or 8 character extension to the end of all affected filenames (i.e. CTB-Locker, Crypt0L0cker, CryptON (Cry9, Cry36, Cry128, Nemesis), Maktub Locker, Alma Locker, Princess Locker, Locked-In, Mischa, Goldeneye, Al-Namrood 2.0, Cerber v4x/v5x and some Xorist variants).

If you find the ransom note or malware itself, samples can be submitted here with a link to this topic.

Based on infection rates we see, the newer Crypt0L0cker variant is one of the most common ransomwares which append a random extension (i.e. ,pzekaq, .ixopyw, .izozyn) to the end of all affected filenames.

Unfortunately, there is no free decryption solution for files encrypted by Crypt0L0cker. However, Dr.Web has been able to assist victims with decrypting files...see here.

Policy from Dr.Web (11/25/15): Free file decryption assistance only for PCs protected by Dr.Web at the moment of infectionIf you're not a licensed user for a Dr.Web product you will have to pay for their services (Rescue Pack). Fees may vary depending on the infection and amount of data to be decrypted.

There is an ongoing discussion in this topic where victims 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.

To avoid unnecessary confusion, this topic is closed.

Thanks
