![]() ![]() ![]() As the scan continues, you can see the file that is currently scanned and decrypted. ![]() Next, it is time to let the Avast Decryption Tool for Babuk do its magic. This option will offer you the best decryption rate. To make sure access to all the encrypted files is granted, you are advised to run the application as an administrator. In case something goes wrong, you can then start all over again with the decryption wizard. It is recommended you do so, just as a precautionary measure. Once the target location is set, you are prompted to create a backup for the encrypted files. Keep in mind that both local and network drives are accepted, and so are individual folders. By default, Avast Decryption Tool for Babuk adds the drives it detects but you can also drag and drop other folders to the main window to populate the list. ![]() First, you get to choose the locations to scan. Thanks to the wizard-based approach of the decryption software utility, using it is a matter of hitting a few “Next” buttons. It goes by the name of Avast Decryption Tool for Babuk, it is extremely easy to use and requires no installation. The attacker requests payment in Bitcoin.The full source code for the Babuk ransomware was leaked by a member of the cyber-criminal group and, as follows, Avast took action and started developing a dedicated decryption tool to help out victims recover their files. The MafiaWare666 ransomware displays a window with instructions detailing how to pay the ransom. Files held hostage are appended with one or all of the following. MafiaWare666 searches specific folder locations (Desktop, Music, Videos, Pictures, and Documents) and encrypts numerous file extensions like 7z, Bat, DivX, HTML, JPEG, JPG, MP3, MP4, ZIP, and everything in between for the most part. It is likely that new or unknown samples may encrypt files differently, making them decryptable without further analysis. Avast researchers found a vulnerability in the encryption schema that allows some of the variants to be decrypted without paying the ransom. MafiaWare666 encrypts files using AES encryption. The MafiaWare666 ransomware strain is written in C# there aren't any obfuscation or anti-analysis techniques. ![]()
