GandCrab ransomware is the type of malware that has become quite the celebrity among ransomware viruses. The virus aims to extort users to make a payment in BitCoin or Dash in return for their encrypted files. The virus used a variety of different file extensions for its different variants. Below you can see all of the versions of GandCrab so far:
- GandCrab .GDCB
- GandCrab .CRAB (v2)
- GandCrab .CRAB (v2.1)
- GandCrab .CRAB (v3)
- GandCrab .KRAB (v4)
- GandCrab .krab (v4.1)
- GandCrab V5.0
- GandCrab 5.0.1
- GandCrab 5.0.2
- GandCrab 5.0.3
- GandCrab 5.0.4
- GandCrab 5.0.5
- GandCrab 5.0.7
- GandCrab 5.0.8
- GandCrab 5.0.9
- GandCrab 5.1.0
- GandCrab 5.1
- GandCrab 5.2
Luckily for all of the victims who have asked for decryptors, now there is a free decryption tool that uses specific RSA-2048 private key, which BitDefender kindly provides in their GandCrab Decryption Tool. These news broke out after the GandCrab creators released free decryption keys for the victims of the virus, who are citizens of Syria.
GandCrab Ransomware Decryption – Update November 2018
A new version of GandCrab ransomware has come out, shortly after BitDefender have released their decryption tool, costing the GandCrab developers around 1 million dollars. The new version is called [wplinkpreview url=”https://sensorstechforum.com/remove-gandcrab-5-0-5-ransomware/”]GANDCRAB 5.0.5 and currently there has been no decryption for it. However, you can check our file recovery and removal video of the 5.0.5 version, which contains more instructions and alternative methods that may help you to try and restore at least some of the files encrypted by v5.0.5.
GandCrab Ransomware Decryption Instructions
The encryption process of the first versions of GandCrab (v1, v2 and v3) used AES-256 encryption with a Cipher Block Chaining. The newer versions (v4 and v5) now use Salsa20 algorithm. The virus used to encrypt a larger portion of the files, risking to damage them, but now it encrypts only a small portion of the files via Salsa20, enough to render them no longer able to be opened. This is how the researchers have managed to reach a breakthrough and the result of that is the BitDefender GandCrab Decryptor. Below, you can find instructions on how you can restore files, encrypted by this version of GandCrab for free.
The most preferred way to remove GandCrab ransomware is by downloading an anti-malware program and running a scan. Such a program is designed to remove malware automatically and to further protect the system.
SpyHunter scanner will only detect the threat. If you want the threat to be automatically removed, you need to purchase the full version of the anti-malware tool.Find Out More About SpyHunter Anti-Malware Tool / How to Uninstall SpyHunter
Decryption Steps
Important! Before beginning decryption, make sure that you are connected to the internet as the BitDefender GandCrab V1, V4, V5 Decryptor works with BitDefneder’s servers to find the decryption keys and recover your files.
Step 1: Download the BitDefender GandCrab Decryptor by clicking on the download button underneath:
Step 2: Save the file where you can find it and Run it:
Step 3: Agree with the Software License Agreement by clicking “I Agree”.
Step 4: If you want specific encrypted files in a single folder to be decrypted, select them by clicking on “Browse”. If you want all files on your computer to be decrypted, tick “Scan Entire System”.
Step 5: Do not forget to tick “Backup Files” before begging, in case something goes wrong. If you see the “Ready to scan” indicator, click on the “Scan” button to begin the decryption process.
Step 6: The software will begin looking for the decryption keys. Be advised that this will definitely take some significant time so arm yourself with patience.
Step 7: When the software has finished decrypting your files, you should find them in the folder:
Be advised to check if all of your files are DECRYPTED successfully before removing the encrypted ones. To remove the encrypted files, you can search them by using Windows search. This can happen by opening “This PC” (My Computer) in Windows and then in the search bar on it’s top-right type the follow and search for it:
→ fileextension:{the extension of your files}
The files should start appearing and when the search is done, press CTRL+A to select all and then press Shift+Del to delete all of the files simultaneously:
Conclusion and Important Tips
Keep in mind that this decryption tool will first try to decrypt 5 files and if this test does not pass, it will not continue, although the probability for that is very low. Also note that BitDefender researchers find it important to receive any feedback, so if you fail to decrypt your files, you should contact them on forensics@bitdefender.com and send them the log file of the decryption process, which is usually located in %Temp%\BDRemovalTool directory.

How to Remove GandCrab Ransomware from Windows.
Step 1: Boot Your PC In Safe Mode to isolate and remove GandCrab Ransomware

Step 2: Uninstall GandCrab Ransomware and related software from Windows
Here is a method in few easy steps that should be able to uninstall most programs. No matter if you are using Windows 10, 8, 7, Vista or XP, those steps will get the job done. Dragging the program or its folder to the recycle bin can be a very bad decision. If you do that, bits and pieces of the program are left behind, and that can lead to unstable work of your PC, errors with the file type associations and other unpleasant activities. The proper way to get a program off your computer is to Uninstall it. To do that:

Follow the instructions above and you will successfully uninstall most programs.
Step 3: Clean any registries, created by GandCrab Ransomware on your computer.
The usually targeted registries of Windows machines are the following:
- HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run
- HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
- HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce
- HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce
You can access them by opening the Windows registry editor and deleting any values, created by GandCrab Ransomware there. This can happen by following the steps underneath:
Tip: To find a virus-created value, you can right-click on it and click "Modify" to see which file it is set to run. If this is the virus file location, remove the value.
Before starting "Step 4", please boot back into Normal mode, in case you are currently in Safe Mode.
This will enable you to install and use SpyHunter 5 successfully.

Hi, Mr Ventsislav Krastev.
Thank you for the information you have kindly posted above.
On November 3rd 2018, I discovered that my PC was affected by GANDCRAB V5.0.4 by referring to JKSLZYRVRQ-DECRYPT. It seems to be everywhere in my computer. I have downloaded BDGandCrabDecryptor.exe.
I have also followed the provided steps properly. Each time I try to scan using Bitdefender GandCrab V1, V4, V5 Decryptor – system looking for encryption key. After a while, it is shown that initialization failed.
Hello Atikah,
I have done a check up on v5.0.4 of GandCrab and BitDefender has stated that it may not be able to work, since 5.0.4 is an updated GandCrab variant that contains fixes in the encryption process. Here is more info about it:
labs.bitdefender.com/2018/10/gandcrab-ransomware-decryption-tool-available-for-free/
I have however heard of people, affected by 5.0.4 who were able to decrypt their files, so this is what i advise you to do:
During the scanning process, the BitDefender decryptor is connecting to the servers of BitDefender in order to look for decryption based on your decryption key in the ransom note. If the server fails to retrieve a key, then you can manually contact BitDefender by clicking on the “Feedback” button on the bottom right of the decrypter. As they say in their page you can also contact them via their support e-mail provided in their tool.
