GANDCRAB 3 ransomware removal instructions
What is GANDCRAB 3?
Recently discovered by malware security researcher, Marcelo Rivero, GANDCRAB 3 is a new variant of high-risk ransomware called GANDCRAB V2.0. After successful system infiltration, GANDCRAB 3 encrypts most stored files and appends filenames with the ".CRAB" extension. For example, "sample.jpg" is renamed to "sample.jpg.CRAB". Compromised data becomes unusable. Once encryption is complete, GANDCRAB 3 creates a text file ("CRAB-DECRYPT.txt") and places a copy in each existing folder. These features are inherited from a previous GANDCRAB 3 version. Unlike past versions, however, GANDCRAB 3 also changes the desktop wallpaper.
The new desktop wallpaper contains a short message stating that data is encrypted and encourages users to read the text file, which provides detailed information. The text file essentially contains a message stating that data decryption requires a unique key generated individually for each victim. Unfortunately this information is accurate. Although it is currently unknown whether GANDCRAB 3 uses symmetric or asymmetric cryptography (this information is not provided), a unique key is necessary to restore data. Developers store all keys on a remote server and blackmail victims for their release - a ransom must be paid. To submit payment, users must follow instructions given on GANDCRAB 3's website. The cost is $1000 and must be paid in Dash or Bitcoin cryptocurrencies. The website also contains a countdown timer. Once it reaches zero, the cost will double. The website also contains a feature allowing users to decrypt a single selected file free of charge. This is supposedly to 'guarantee' that restoring data is possible. Despite their threats and promises, cyber criminals can never be trusted. Note the ransom demand in this case is extremely high (few will pay thousands of dollars, even for their personal files such as music, pictures, etc.) Furthermore, paying typically gives no positive result. Research shows that ransomware developers often ignore victims, once payments are submitted and victims are simply scammed. As well as losing their money, unsuspecting users will support cyber criminals' malicious businesses. For these reasons, never attempt to contact these people and certainly do not submit any payments. Unfortunately, there are no tools capable of decrypting data compromised by GANDCRAB 3 and there is just one solution: to restore everything from a backup.
Screenshot of a message encouraging users to pay a ransom to decrypt their compromised data:
GANDCRAB 3 shares many similarities with dozens of other ransomware-type viruses such as 8chan, OBLIVION, Kraken 2.0, and nRansom. These viruses are developed by different cyber criminals, but have identical behavior - all encrypt data and make ransom demands. Ransomware-type viruses typically have just two major differences: 1) size of ransom, and; 2) type of encryption algorithm used. Most use algorithms designed to generate unique decryption keys (for instance, RSA, AES, etc.) Therefore, decrypting data without involvement of developers (contacting these people is not recommended) is impossible, unless the malware is not fully developed or has certain bugs/flaws (e.g., the key is hard-coded, stored locally or similar). Ransomware is one of the main reasons why you should maintain regular data backups, however, it is very important to store them on a remote server or unplugged storage device, otherwise backups are encrypted with regular data.

How to protect yourself from ransomware infections?
The key to computer safety is caution. Therefore, pay close attention when browsing the Internet. Before opening email attachments, ensure that files are relevant and have been received from recognizable/trustworthy email addresses. If not, delete the emails immediately and certainly do not open any file attachments. Furthermore, never use any third party download/installation tools, since they often include rogue apps. Download your software from official sources only, using direct download links. Keep installed applications up-to-date and use a legitimate anti-virus/anti-spyware suite, however, since criminals proliferate malware via fake updaters, software should be renewed using implemented functions or tools provided by the official developer only.

Update 25 October, 2018 - GANDCRAB developers have recently leaked almost a thousand of decryption keys that allow victims from Syria decrypt data for free. BitDefender immediately took an advantage and released a decryption tool that could help said victims easily decrypt data. However, after the initial release, BitDefender teamed up with Europol and a number of police departments from various countries (such as Romania, Netherlands, United States, and many more). While working together, they've discovered GANDCRAB's flaw which can be abused to decrypt data for free. The tool is universal (meaning it can help victims from all over the world) and it is compatible with 1st, 4th and 5th versions of GANDCRAB. At the time of writing this decryption tool is being updated and will eventually be able to decrypt data compromised by 2nd and 3rd versions of GANDCRAB as well. You can find more information in this article and you can download the decrypter by clicking this link.
Decryption tool developed by BitDefender, Europol and a number of police departments looks like this:

1. During your computer start process, press the F8 key on your keyboard multiple times until the Windows Advanced Options menu appears, and then select Safe Mode with Command Prompt from the list and press ENTER.
2. When Command Prompt mode loads, enter the following line: cd restore and press ENTER.
3. Next, type this line: rstrui.exe and press ENTER.
4. In the opened window, click "Next".
5. Select one of the available Restore Points and click "Next" (this will restore your computer system to an earlier time and date, prior to the GANDCRAB 3 ransomware virus infiltrating your PC).
6. In the opened window, click "Yes".
7. After restoring your computer to a previous date, download and scan your PC with recommended malware removal software to eliminate any remaining GANDCRAB 3 ransomware files.
To restore individual files encrypted by this ransomware, try using the 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 GANDCRAB 3 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.
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 protect your computer from file encryption ransomware such as this, use reputable antivirus and anti-spyware programs. As an extra protection method, you can use programs called HitmanPro.Alert and EasySync CryptoMonitor, which artificially implant group policy objects into the registry to block rogue programs such as GANDCRAB 3 ransomware.
Note that Windows 10 Fall Creators Update includes a "Controlled Folder Access" feature that blocks ransomware attempts to encrypt your files. By default, this feature automatically protects files stored in the Documents, Pictures, Videos, Music, Favorites as well as Desktop folders.
Windows 10 users should install this update to protect their data from ransomware attacks. Here is more information on how to get this update and add an additional protection layer from ransomware infections.
HitmanPro.Alert CryptoGuard - detects encryption of files and neutralises any attempts without need for user-intervention:
Malwarebytes Anti-Ransomware Beta uses advanced proactive technology that monitors ransomware activity and terminates it immediately - before reaching users' files:
- The best way to avoid damage from ransomware infections is to maintain regular up-to-date backups. More information on online backup solutions and data recovery software Here.
