This is the result of the STOP Ransomware attack. I have been tracking the malicious work of this program since December 2017. Now on the forum a lot of victims from different variants of this Ransomware. In some cases, the files can be decrypted.
@Demonslay335 (the developer of the STOPDecrypter) collects information from the victims, writes data and tries to update the STOP Decrypter. After that, victims can try to decrypt the files. A positive result and a lucky chance are not always possible.
