About TrueCrypt Ransomware
TrueCrypt ransomware uses a pair of keys – a public (encryption) and a private (decryption) keys. The public key denotes RSA-2048 algorithm and the private key indicates AES-256 algorithm. The private key is stored on C&C (Command and Control) servers controlled by hackers. Any type of data can be affected: .txt, .doc, .pdf, .zip, .rar, etc. The following filename extensions are appended with .enc extension. Then, the files are compressed to %APPDATA%\Microsoft\TrueCrypter\Encrypted.dat file and locked. The encryption process is over.
Your desktop wallpaper is replaced with the image of the ransom note. The message states the fact of encryption, the ransom required and the payment details. The compensation is equivalent to 0.2 Bitcoins which is equal to 89.81 USD at the moment.

They store copies of your files that point of time when the system restore snapshot was created. Usually TrueCrypt Ransomware tries to delete all possible Shadow Volume Copies, so this methods may not work on all computers. However, it may fail to do so. Shadow Volume Copies are only available with Windows XP Service Pack 2, Windows Vista, Windows 7, and Windows 8. There are two ways to retrieve your files via Shadow Volume Copy. You can do it using native Windows Previous Versions or via Shadow Explorer. a) Native Windows Previous Versions Right-click on an encrypted file and select Properties → Previous versions tab. Now you will see all available copies of that particular file and the time when it was stored in a Shadow Volume Copy.
