All files it locks get the .[].NOT_OPEN filename extension – it is placed at the end of the file next to the original file’s extension. You should also find the !_HOW_RECOVERY_FILES_!.txt file dropped in all the directories on your computer after the successful entrance of this computer threat. The text file dropped contains a message that consists of three parts. The first one explains what has happened to those files that can no longer be launched. The second one tells users what they can do to unlock their files. They need to use the special decryptor program that they can get from the ransomware developer. Users need to send an email with the unique ID in the subject line to first to get further instructions. We suspect that you will have to pay money for the decryptor. Unfortunately, we cannot promise that it will be sold at a low price. The third part of the message tells users that they can send up to 3 files to get them decrypted for free. They cannot contain important information.
