TrueCrypt ransomware removal instructions

What is TrueCrypt?

TrueCrypt is another ransomware infection that infiltrates systems and then encrypts stored files. Types of targeted files include .rar, .7zip, .php, .doc., .pdf, and many others. During encryption, TrueCrypt adds the .enc extension to compromised files. This ransomware uses AES-256 encryption and, thus, public (encryption) and a private (decryption) keys are generated during the encryption process. Therefore, files can supposedly only be restored using the private key, which is stored on C&C (Command & Control) servers managed by cyber criminals. To receive this key, victims must pay a ransom.

TrueCrypt ransomware changes the victim's desktop wallpaper with an image containing a message, which states that files are encrypted and the victim must pay a specific sum to restore them. Developers of TrueCrypt accept Bitcoins and Amazon Gift Cards. The size of ransom is equivalent to 0.2 BTC (at time of research, equivalent to $93.96) or $115 (depending on the payment method chosen by the victim). It is also stated that payment must be made within 72 hours, otherwise the private key will be deleted forever and it will then be impossible to restore the encrypted files. Victims are provided with step-by-step payment instructions. Furthermore, they are able to contact the cyber criminals via an e-mail address provided if any help is required. This ransomware stores the list of encrypted files within the %APPDATA%\Microsoft\TrueCrypter\Encrypted.dat file. Fortunately, the TrueCrypt decryptor, which victims must use to send the Bitcoin transaction/Amazon Gift Card ID, has a major flaw. There is no need to pay the ransom, nor enter any kind of ID. Victims simply need to click the 'Pay' button, confirm that the information is correct, and the files will be automatically decrypted. The ransomware will be automatically uninstalled afterwards.

TrueCrypt decrypt instructions

Research results show that paying the ransom does not guarantee that your files will ever be decrypted. Therefore, you should never attempt to contact cyber criminals, nor pay the ransom. TrueCrypt is similar to Cerber, TeslaCrypt, Locky, CryptoWall, and tens of other ransomware infections. All encrypt files using an asymmetric encryption method. The only difference is the size of ransom, which usually fluctuates between 0.5 and 1.5 Bitcoin. Be aware that malware such as TrueCrypt is often distributed using malicious email attachments, peer-to-peer (P2P) networks (e.g., Torrent), fake software updates, and/or trojans. You should, therefore, use legitimate anti-virus/anti-spyware, keep your installed software up-to-date, and be cautious when downloading files sent from unrecognized/suspicious and third party peer-to-peer networks.

Text presented on the TrueCrypt desktop wallpaper:

If you see this text, probably your computer got encrypted by TrueCrypter. This means all your important files (documents, images, etc.) are now unaccessible and you will lose them forever unless your pay a sum of money to get your decryption key.
The decryption key uses the RSA-2048 algorithm, impossible to crack. Your files will be lost forever without paying.

If you don;t case about your files, just uninstall this software.
If you lost the application because your antivirus deleted it, or you need help, you can contact is on our email:

(You only have 72 hours before your private key will be destroyed, hurry up if you want to save your files!)

Text presented within the information window:

>What happened?

All your important documents on this computer (Images, Videos, etc.) were encrypted using an unique RSA-2048 Public Key.

>How can I restore my files?

In order to decrypt your files you need your Private Key, which is situated on our hidden server. The only way to obtain it, is by paying a sum of money. Without the key, there is no way to unblock your files.

>How can I pay?

We currently accept payments in Bitcoins or AGCs (Amazon Gift Cards).

1. During your computer start process, press the F8 key on your keyboard multiple times until the Windows Advanced Options menu appears, and then select Safe Mode with Command Prompt from the list and press ENTER.

Boot your computer in Safe Mode with Command Prompt

2. When Command Prompt mode loads, enter the following line: cd restore and press ENTER.

3. Next, type this line: rstrui.exe and press ENTER.

system restore using command prompt rstrui.exe

4. In the opened window, click "Next".

restore system files and settings

5. Select one of the available Restore Points and click "Next" (this will restore your computer system to an earlier time and date, prior to the TrueCrypt ransomware virus infiltrating your PC).

select a restore point

6. In the opened window, click "Yes".

run system restore

7. After restoring your computer to a previous date, download and scan your PC with recommended malware removal software to eliminate any remaining TrueCrypt ransomware files.

To restore individual files encrypted by this ransomware, try using Windows Previous Versions feature. This method is only effective if the System Restore function was enabled on an infected operating system. Note that some variants of TrueCrypt are known to remove Shadow Volume Copies of the files, so this method may not work on all computers.

To restore a file, right-click over it, go into Properties, and select the Previous Versions tab. If the relevant file has a Restore Point, select it and click the "Restore" button.

Restoring files encrypted by CryptoDefense

If you cannot start your computer in Safe Mode with Networking (or with Command Prompt), boot your computer using a rescue disk. Some variants of ransomware disable Safe Mode making its removal complicated. For this step, you require access to another computer.

To regain control of the files encrypted by TrueCrypt, you can also try using a program called Shadow Explorer. More information on how to use this program is available here.

To protect your computer from file encrypting ransomware such as this, use reputable antivirus and anti-spyware programs. As an extra protection method, you can use programs called HitmanPro.Alert and Malwarebytes Anti-Ransomware, which artificially implant group policy objects into the registry to block rogue programs such as TrueCrypt ransomware.)

HitmanPro.Alert CryptoGuard - detects encryption of files and neutralises any attempts without need for user intervention:
