What is GANDCRAB 5.3?

Discovered by Jakub Kroustek, GANDCRAB 5.3 (also known as GANDCRAB V5.3) is high-risk ransomware that belongs to the GANDCRAB malware family. After successful infiltration, GANDCRAB 5.3 encrypts most stored data and appends filenames with a random-string extension. For example, "sample.jpg" might be renamed to a filename such as "sample.jpg.awqrsj". Additionally, GANDCRAB 5.3 changes the desktop wallpaper and places a text file ("AWQRSJ-MANUAL.txt") in every existing folder.

GANDCRAB 5.3's desktop wallpaper displays a short message stating that data is encrypted and can only be restored with a unique decryption tool (created by developers of GANDCRAB 5.3) that victims must purchase. The wallpaper also encourages victims to read the new text file for detailed instructions. The file also states that data is encrypted and can only be restored using a unique decryption key that, again, victims must purchase. Cyber criminals encourage victims to purchase a decryption tool with the key embedded within. The cost is not specified - all details are provided via email, however, cyber criminals typically demand $500-$1500 and ransoms must be paid in Bitcoins, Monero, Ethereum, or another cryptocurrency, Regardless of the cost, do not pay. Research shows that cyber criminals often ignore victims once payments are submitted. Therefore paying usually gives no positive result and users are scammed. Therefore, ignore all requests to submit payments or even contact these people. Unfortunately, there are currently no tools capable of cracking GANDCRAB 5.3 encryption and restoring data free of charge, however, Bitdefender has developed a decryption tool for previous versions of GANDCRAB ransomware. This situation might change, but for now, the only solution is to restore everything from a backup if one has been created prior to infection.

There are dozens of ransomware-type infections that share similarities including CubeGotcha, and Guvara. These are just some examples from many. Although the developers are different, the behavior is identical - these infections compromise data (typically, by encryption) and make ransom demands in exchange for file recovery. Most of these infections employ cryptographies that generate unique decryption keys. Therefore, unless the virus is still in development or has certain bugs/flaws, restoring data manually without involvement of developers (contacting these people is not recommended) is impossible. Ransomware presents a strong case for maintaining regular backups, however, store them on unplugged storage devices or remote servers, since locally stored backups are compromised together with regular data.

How did ransomware infect my computer?

Ransomware is usually proliferated using spam email campaigns, third party software download sources, fake software updaters/cracks and trojans. Spam campaigns are used to send hundreds of thousands of emails containing deceptive messages and malicious attachments. The messages present the attachments as "important documents" (e.g., bills, invoices, receipts, etc.) and encourage users to open them, however, this results in various system infections. Unofficial download sources present malicious executables as legitimate software, thereby tricking users into manually downloading and installing malware. Fake updaters infect systems by exploiting outdated software bugs/flaws or simply downloading and installing malware rather than updates. The same applies to software cracks. The idea behind cracking tools is to activate paid software free of charge, however, most are fake and criminals use them to proliferate malware. Therefore, users are much more likely to infect their computers than gain access to paid features. Finally, trojans are malicious applications that stealthily infiltrate computers and continue to inject additional malware - "chain infections".

How to protect yourself from ransomware infections?

The main reasons for computer infections are poor knowledge and careless behavior. The key to computer safety is caution. Therefore, pay close attention when browsing the internet and downloading, installing, and updating software. Never open email attachments if they are irrelevant or the sender seems suspicious/unrecognizable. Download apps from official sources only, using direct download links. Third party downloaders/installers often include rogue apps, and thus these tools should not be used. Keeping install applications and operating systems up-to-date is, however, use only implemented functions or tools provided by the official developer. Bear in mind that software piracy is considered a cyber crime. Furthermore, the risk of infections is extremely high. Therefore, never attempt to crack installed apps. Lastly, use a reputable anti-virus/anti-spyware suite - these tools detect and eliminate malware before the system is harmed. If your computer is already infected with GANDCRAB 5.3, 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 5.3 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 5.3 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 5.3 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.

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 5.3, 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 5.3 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.

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.
