What is SD (Unlock11) Ransomware
If you are no longer able to access your files, then this is because ransomware infected your system. SD (Unlock11) Ransomware is not an exception since it ciphers users’ data with RSA + Salsa20 algorithm and adds brand new .[firstname.lastname@example.org].enc extension to each file. As an example, standard 1.mp4 will be renamed to 1.mp4.[email@example.com].enc after the encryption process is done. It is necessary to point out that .enc extension is more generic and has been exploited by several types of ransomware including MOTD, TrueCrypter, and Cryptohasyou. After successful encryption, the program automatically opens a ransom note ReadMeToDecrypte.txt, which contains the details on how to decrypt your data.
