Bitdefender Bart Decryptor

What differentiates Bart from other ransomware families is its capability to perform file encryption without an active Internet connection. To do so, it first erases all the system restore points to make it impossible to recover data, and then uses information from the target computer to generate an encryption key, which, in turn, is encrypted using a master key.

Fortunately, some of the most important security companies have taken action to create decryption tools that can be used to unlock encrypted files. Bitdefender's utility is named Bart Decryptor.

Depending on the Bart iteration that reached your system, you should have files with the “.bart.zip”, “.bart” and “.perl” extensions. What the Bitdefender Bart Decryptor does is scan your computer for such files and attempt to recover the lost data, to avoid having to pay the ransom.

No installation is required, and the utility starts as soon as you double-click the installer. The main and only window is simple, allowing you to select the location to scan. Alternatively, you can configure Bitdefender Bart Decryptor to analyze the entire system, but note that it might take a while for it to complete this task.

It is advisable to create a backup of your data before using Bitdefender Bart Decryptor, as Bitdefender itself recommends. While the application should be able to decrypt your files successfully, the process is complicated and might result in damage and data loss.

The Bitdefender Bart Decryptor is created as part of the No More Ransom initiative and promises to try decrypting files locked by the known versions of the Bart ransomware. Please note that you should scan your system with a permanent security solution to remove the ransomware and then use this decryption tool.
