Short bio

Ransom.Troldesh is Malwarebytes’ detection name for a type of ransomware that is also known as Shade. It is thought to be of Russian origin and has been around since 2014.


Ransom.Troldesh adds different extensions to the encrypted files, depending on the version of the ransomware. The most well-known extensions are:

  • .xbtl
  • .cbtl
  • .no_more_ransom
  • .better_call_saul

When the ransomware has finished encrypting files it will show a ransom note similar to this one:

The README.txt files are dropped in many folders on the affected system. Most likely in every folder that has an encrypted file in it.

Type and source of infection

Ransom.Troldesh is ransomware. Ransomware is a type of malware that prevents users from accessing their system or personal files and demands ransom payment in order to regain access.
Ransom.Troldesh is spread by malspam, typically in the form of attached .zip files. This ransomware sometimes uses a CMS on a compromised site to host downloads.


Ransom.Troldesh uses a strong encryption, so sometimes there is no way to regain your encrypted files for free, but there are free decryption tools available for some of the Troldesh variants. Check NoMoreRansom.org for your options.


Malwarebytes protects users from Ransom.Troldesh by using real-time protection.

Malwarebytes blocks Ransom.Troldesh


Malwarebytes can detect and remove Ransom.Troldesh without further user interaction.

  1. Please download Malwarebytes to your desktop.
  2. Double-click mb3-setup-consumer-{version}.exe and follow the prompts to install the program.
  3. Then click Finish.
  4. Once the program has fully updated, select Scan Now on the Dashboard. Or select the Threat Scan from the Scan menu.
  5. If another update of the definitions is available, it will be implemented before the rest of the scanning procedure.
  6. When the scan is complete, make sure that all Threats are selected, and click Remove Selected.
  7. Restart your computer when prompted to do so.

Take note, however, that removing this ransomware does not decrypt your files. You can only get your files back from backups you made before the infection happened.
