GANDCRAB 2 ransomware removal instructions
What is GANDCRAB 2?
GANDCRAB 2 is an updated version of the high-risk ransomware-type virus called GANDCRAB. GANDCRAB 2 was first discovered by MalwareHunterTeam. Once infiltrated, this malware encrypts most stored files and adds the ".CRAB" extension to the name of each compromised file. From this point, files become unusable. After successfully encrypting files, GANDCRAB 2 creates a text file ("CRAB-DECRYPT.txt") and places a copy in each existing folder.
The new text file contains a message informing victims of the encryption and stating that files can only be restored using a private key generated individually for each victim. Unfortunately, this information is accurate. It is currently unknown whether GANDCRAB2 uses symmetric or asymmetric cryptography, however, decryption requires a unique key. Furthermore, developers hide all keys on a remote server and make ransom demands for their release. The message in the text file encourages victims to visit GANDCRAB 2's website stored on the Tor network. After opening this site, users are prompted with a message stating that the key (together with a decryption tool) is available at a cost (equivalent value = $400 in the Dash cryptocurrency). It is also stated that, after 48 hours, the cost will double. Victims are permitted to decrypt one selected file free of charge as a 'guarantee' that decryption is possible. Despite these threats and demands, cyber criminals can never be trusted. Research shows that developers of ransomware-type viruses often ignore victims, once payments are submitted. Therefore, paying ransoms typically gives no positive results and victims are scammed. You are strongly advised to ignore all requests to contact these people or pay any ransoms. Unfortunately, there are currently no tools capable of restoring files encrypted by GANDCRAB2 (the Bitdefender tool developed for the original GANDCRAB version will not help). Therefore, the only solution is to restore everything from a backup.
Screenshot of a message encouraging users to pay a ransom to decrypt their compromised data:
There are dozens of ransomware-type viruses virtually identical to GANDCRAB 2. For example, Jigsaw, LockyCrypt, Dharma, ANNABELLE, and Saturn. Although these viruses are designed by different cyber criminals, all have identical behavior - they encrypt data and make ransom demands. In most cases, these viruses have just two major differences: 1) size of ransom, and; 2) type of cryptography used. Unfortunately, most employ encryption algorithms (such as RSA, AES, and so on) that generate unique decryption keys. Therefore, unless the malware has certain bugs/flaws (e.g., the key is hard-coded, stored locally or similar), file decryption manually is impossible. Ransomware is one of the main reasons why you should keep regular data backups, however, it is very important to store backup files on a remote server (e.g., Cloud) or unplugged external storage, otherwise they will also be encrypted.

How to protect yourself from ransomware infections?
The main reasons for computer infections are poor knowledge and careless behavior - the key to safety is caution. Therefore, pay close attention when browsing the Internet. Never open files received from suspicious email addresses. These emails should be deleted without reading. It is also recommended that you download your applications from official sources only using direct download links. Third party downloaders/installers often include rogue apps - these tools should not be used. Furthermore, keep installed applications up-to-date and use a legitimate anti-virus/anti-spyware suite, but remember that criminals proliferate ransomware using fake updaters. Therefore, you are advised to use implemented update functions or tools provided by the official developer only.

Update 24 April, 2018 - Cyber criminals have released GandCrab V2.1 ransomware. It still uses .CRAB extension for encrypted files. Cyber criminals are using Magnitude exploit kit to spread this ransomware:
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:

If you cannot start your computer in Safe Mode with Networking, try performing a System Restore.
Video showing how to remove ransomware virus using "Safe Mode with Command Prompt" and "System Restore":
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 GANDCRAB2 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 GANDCRAB2 ransomware files.
To restore individual files encrypted by this ransomware, try using 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 GANDCRAB2 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 GANDCRAB2 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.
