GANDCRAB V5.0.3 ransomware removal instructions

What is GANDCRAB V5.0.3?

GANDCRAB V5.0.3 is an updated version of a high-risk ransomware - GandCrab 5.0.2. After successfully infiltrating the system, GANDCRAB V5.0.3 encrypts most stored files and appends filenames with the ".zkffjmip" extension. For instance, "sample.jpg" is renamed to "sample.jpg.zkffjmip". Encrypted data instantly becomes unusable. As well as compromising files, GANDCRAB V5.0.3 also changes the desktop wallpaper and places a copy of a text file named "ZKFFJMIP-DECRYPT.txt" in every existing folder.

The new desktop wallpaper contains a short message stating that data is compromised and that victims must read the "ZKFFJMIP-DECRYPT.txt" file. This text file also delivers a message stating that data is encrypted and can only be restored using a unique key. Unfortunately, this information is accurate. Although it is currently unknown whether GANDCRAB V5.0.3 uses symmetric or asymmetric cryptography, each victim receives a unique decryption key necessary to restore data. Cyber criminals hide all keys on a remote server, and thus victims must pay ransoms for their release. To achieve this, they must visit GANDCRAB V5.0.3's website and follow the instructions. The website states that the key is equivalent to a value of $800 and this must be paid in Bitcoins. The website also contains a countdown timer. Once it reaches zero, the cost is doubled. In any case, you should never trust cyber criminals or submit any payments. Research shows that ransomware developers are very likely to ignore victims, once payments are submitted. Therefore, paying usually gives no result and users are scammed. Ignore all requests to submit payments. Unfortunately there are no tools capable of cracking GANDCRAB V5.0.3 encryption and restoring data free of charge. You can only restore everything from a backup.

GANDCRAB V5.0.3 decrypt instructions

The internet is full of ransomware-type viruses that share similarities with GANDCRAB V5.0.3 including Garrantydecrypt, Koolova, and Dharma-Btc. These are just some examples from many. Although they have different developers, these viruses have identical behavior - they encrypt data and make ransom demands. The only major differences are size of ransom and type of encryption algorithm used. Unfortunately, most use cryptography (e.g., AES, RSA, etc.) that generates unique decryption keys. Therefore, it is virtually impossible to decrypt data without involvement of developers (contacting these people is not recommended). The only solutions are ransomware not being fully developed or having certain bugs/flaws (for instance, the key is hard-coded, stored locally, and so on).

How did ransomware infect my computer?

There are many ways to proliferate ransomware, however, the most common tools/methods are trojans, fake software updaters, unofficial download sources, and spam email campaigns. Trojans cause so-called "chain infections" - one virus proliferates another. Fake update tools infect systems in two ways: by exploiting old software bugs/flaws or simply downloading and installing malware rather than promised updates. Third party download sources (free file hosting websites, freeware download websites, peer-to-peer [P2P] networks, etc.) present malicious executables as legitimate software, thus tricking users into downloading and installing malware. Spam campaigns proliferate malicious attachments that, once opened, infiltrate viruses into the system.

Threat Summary:

How to protect yourself from ransomware infections?

Lack of knowledge and careless behavior are the main reasons for computer infections. Caution is the key to safety. Therefore, pay attention when downloading/installing/updating software and browsing the internet. Keep installed applications up-to-date, however, this should be achieved through implemented features or tools provided by the official developer. In addition, download apps from official sources only, using direct download links. Third party downloaders/installers often include rogue programs, and thus these tools should never be used. Think twice before opening email attachments. Files that are irrelevant/unexpected and those received from suspicious/unrecognizable email addresses should never be opened. Having a reputable anti-virus/anti-spyware suite installed and running is also paramount. If your computer is already infected with GANDCRAB V5.0.3, we recommend running a scan with Spyhunter for Windows to automatically eliminate this ransomware.

7. After restoring your computer to a previous date, download and scan your PC with recommended malware removal software to eliminate any remaining GANDCRAB V5.0.3 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 V5.0.3 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.
