Infected with Mimicry Ransomware? Need to decrypt your files?
What is Mimicry Ransomware
Mimicry Ransomware, also known as ShivaGood Ransomware, is another cryptovirus, extorting money from users. As with similar extortion programs, this encrypts data on the user’s computer, which can represent one or another value. It can be office documents, PDF files, video and audio files, multimedia and so on. Of course, these files become useless after encryption. In addition, it is worth noting that it is almost impossible to restore files since the virus removes shadow copies of files and system restore points. Mimicry uses the AES algorithm for encryption and changes the extension of files to .good. The information note is HOW_TO_RECOVER_FILES.txt, which contains a fairly detailed instruction for decrypting files. Look at this:
