Troldesh ransomware removal instructions

What is Troldesh?

Troldesh is a family of ransomware-type viruses. Malware from this family is created using a 'development kit', which various affiliates utilize with their payment email addresses, and then distribute to infect as many computers as possible. After system infiltration, these viruses encrypt victims' files using an asymmetric encryption algorithm (for example, RSA-2048) and modify the filenames. For instance, if the original file copy was named filesample.jpg, it would be renamed to filesample.jpg.[VICTIM'S ID].[DEVELOPERS' EMAIL].xtbl. Never variants of this ransomware use .dexter and .crypted000007 extensions for encrypted files. These viruses also change the desktop wallpaper and create a number of text files (named, for example, How to decrypt your files.txt), placing them in each folder containing the encrypted files.

The text file and desktop wallpaper state that the victim must use the email address provided to restore compromised data. A reply is then received stating that the victim must pay a ransom to receive a decryption key. Payment instructions are also provided. This ransom must be paid in Bitcoins (BTC), and the size usually fluctuates between 0.5 and 1.5 BTC (at time of research, 1 BTC was equivalent to $538.06). Be aware, however, that cyber criminals often ignore victims, despite payments made. Therefore, you should never attempt to contact these criminals or pay any ransom. Two keys - public (encryption) and private (decryption) - are generated when encrypting files with the asymmetric algorithm. Decryption without the private key is impossible. Nevertheless, some ransomware has flaws and, therefore, you can try to restore your files using Rakhni Decryptor developed by the Kaspersky team (download link). Otherwise, you can only restore your files/system from a backup.

The list of currently-known ransomware-type viruses belonging to Troldesh family includes Vegclass, Ecovector, Mahasaraswati, JohnyCryptor, and Green_Ray. All have identical behavior - they encrypt files and then make ransom demands. This type of malware is most likely to be distributed using malicious email attachments (for example, fake job application forms that appear as Microsoft Word documents - they are, in fact, Javascript files that download ransomware), peer-to-peer networks, dubious software updates, and trojans. Therefore, use legitimate anti-spyware or anti-virus software and keep your installed applications up-to-date. Furthermore, never open attachments sent from unrecognized/suspicious email addresses and download your desired files/software from trusted sources (for example, official download websites).

Victims of this ransomware can try using ShadeDecryptor tool by Kaspersky to regain control of their compromised data. More info and download link HERE. Here’s a screenshot of ShadeDecryptor:

7. After restoring your computer to a previous date, download and scan your PC with recommended malware removal software to eliminate any remaining Troldesh 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 Troldesh 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 Troldesh, you can also try using a program called Shadow Explorer. More information on how to use this program is available here.
