Darkside Ransomware Decryption Tool
We’re happy to announce the availability of a decryptor for Darkside. This family of ransomware has emerged in August 2020 and operates operate under a ransomware-as-a-service business model.
How to use this tool
Step 1: Download the decryption tool below and save it on your computer.
Step 2: Double-click the file (previously saved as BDDarkSideDecryptor.exe) and allow it to run.
Step 3: Select “I Agree” in the License Agreement screen
Note: The tool attempts to identify the file extension of the encrypted files automatically. In this example, the encrypted files have the *.e392d905 extension. Please make sure that you have encrypted files on the system you are running the tool.
Step 4: Select “Scan Entire System” if you prefer the tool to search for all encrypted files. Alternatively, add the path to the location you previously moved the encrypted files.
We strongly recommend that you also select “Backup files” before starting the decryption process to avoid potential loss or corruption during decryption. Then press “Start Tool”.
At the end of this step, your files should be decrypted.
If you encounter any issues, please contact us at firstname.lastname@example.org.
If you have checked the backup option, you will see both the encrypted and decrypted files. You can also find a log of the decryption process in the %temp%\BDRemovalTool folder.
To remove the encrypted files left behind, you should search for files matching the extension and mass-remove them. We do not encourage you to do this until you made sure that your files can be opened safely and there is no damage to the decrypted files.
