TrueCrypt Ransomware

TrueCrypt Ransomware is another species of ransomwares trojans. It bears the name of the application locking data from unauthorized access.

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.

The compensation is equivalent to 0.2 Bitcoins which is equal to 89.81 USD at the moment. What is quite peculiar to TrueCrypt ransomware, is that the developers accept AGCs, that is Amazon Gift Cards worth 115USD (this would cost you more than the usual BTC transfer).

Step 3. Restore TrueCrypt Ransomware affected files using Shadow Volume Copies

If you do not use System Restore option on your operating system, there is a chance to use shadow copy snapshots. 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 PropertiesPrevious 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. Choose the version of the file you want to retrieve and click Copy if you want to save it to some directory of your own, or Restore if you want to replace existing, encrypted file. If you want to see the content of file first, just click Open.

Step 4. Use Data Recovery programs to recover TrueCrypt Ransomware encrypted files

There are several data recovery programs that might recover encrypted files as well. This does not work in all cases but you can try this:
  • We suggest using another PC and connect the infected hard drive as slave. It is still possible to do this on infected PC though.
  • Download a data recovery program.
  • Install and scan for recently deleted files. Data Recovery Pro
Note: In many cases it is impossible to restore data files affected by modern ransomware. Thus I recommend using decent cloud backup software as precaution. We recommend checking out Carbonite, BackBlaze, CrashPlan or Mozy Home.
