GandCrab 5.0.9 ransomware removal instructions

What is GandCrab 5.0.9?

Discovered by Marcelo Rivero, GandCrab 5.0.9 is a variant of a high-risk ransomware-type infection called GandCrab. Like most viruses of this type, it is designed to encrypt data, rendering affected files unusable. It renames each encrypted file by appending the victim's ID to the file extension (e.g. ".wwzaf"). For example, it renames "1.jpg" to "1.jpg.wwzaf", and so on. GandCrab 5.0.9 also generates a ransom note within a text file named "WWZAF-DECRYPT.txt". As with the appended extension, this filename is associated with the victim's ID. GandCrab 5.0.9 places the text file in each folder containing encrypted files and changes the desktop wallpaper.

When GandCrab 5.0.9 ransomware is executed, a pop-up window appears containing the message "We will become back very soon;)". This information is of little use, but the main details are presented in the "WWZAF-DECRYPT.txt" file (or other ransom messages). According to GandCrab 5.0.9 developers, all of the user's data (photos, various documents, databases, etc.) have been encrypted/locked and the only way to retrieve (decrypt/unlock) them is to purchase a private (unique) decryption key (in effect, pay a ransom). In this case, GandCrab 5.0.9 victims are required to download a Tor browser, open the link provided, and then follow further instructions. This ransomware urges victims not to try to modify the encrypted files. It is not known which cryptography algorithm (symmetric or asymmetric) cyber criminals employ to encrypt files using this virus. Regardless, most cyber criminals use algorithms that generate unique keys. They store the keys on remote servers accessible only by them. Furthermore, there are no tools capable of cracking GandCrab 5.0.9 encryption free of charge (at least not at present). Note that cyber criminals cannot be trusted, since they often ignore victims even decryption tools/keys are purchased and ransoms paid. The best solution in these cases is to use an existing backup and restore files from there.

StevenSeagal, CmdRansomware, and Risk are just some examples of many other viruses of this type. Generally, ransomware developers use these infections to encrypt data and make ransom demands. Typically, the only differences between these viruses are cryptography algorithm used for encryption and size of ransom (cost of decryption tool/key). Free decryption (without involvement of cyber criminals) is impossible unless ransomware is still in development or contains unfixed bugs/flaws. To avoid data loss, maintain regular backups and store them on remote servers or unplugged storage devices.

How did ransomware infect my computer?

It is not known how GandCrab 5.0.9 developers proliferate this infection, however, cyber criminals often use spam email campaigns, trojans, various untrustworthy software download channels, and fake software updaters. They use spam campaigns by sending a number of emails that contain a malicious attachment. The presented attachment might be a Microsoft Office document, executable file (.exe), archive file (such as RAR), PDF file, and so on. Computers become infected when these infected attachments are opened or permission to perform malicious actions is given. Various free file hosting, freeware download websites, peer-to-peer (P2P) networks, and other untrustworthy software download sources are used to present infected files as legitimate. In these cases people, are often tricked into downloading and installing viruses. Trojans are infections designed to distribute other viruses. Thus, having a trojan installed puts computers at risk of installation of additional viruses. Fake software updaters cause damage by downloading viruses rather than the updates or by exploiting bugs/flaws of installed and outdated software.

How to protect yourself from ransomware infections?

To prevent computer infection with ransomware-type (or other) viruses, we strongly recommend that you browse the Internet, install, download and update software with care. Do not open attachments that are presented in emails received from unknown/untrustworthy, suspicious addresses. If you suspect that an email is irrelevant, simply ignore it. Update your software (or the operating system) using implemented functions or tools provided by official developers only. Avoid downloading software using untrustworthy, unofficial websites or third party downloaders. Third party download or installation set-ups often include rogue applications that might cause system infections. Have a reputable anti-spyware or anti-virus suite installed. These programs can detect and eliminate viruses before they can do any damage. If your computer is already infected with GandCrab 5.0.9, we recommend running a scan with Spyhunter for Windows to automatically eliminate this ransomware.

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 5.0.9 ransomware virus infiltrating your PC).

select a restore point

6. In the opened window, click "Yes".

run system restore

7. After restoring your computer to a previous date, download and scan your PC with recommended malware removal software to eliminate any remaining GandCrab 5.0.9 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 GandCrab 5.0.9 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.

Restoring files encrypted by CryptoDefense

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 regain control of the files encrypted by GandCrab 5.0.9, you can also try using a program called Shadow Explorer. More information on how to use this program is available here.

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 5.0.9 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.

Controll Folder Access

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.
