What is GandCrab 5.2 ransomware?

GandCrab 5.2 ransomware – a decryptable malware variant

GandCrab 5.2A ransom note explains users that they need to pay $500 in order to restore the locked data GandCrab 5.2 is the cryptovirus that was released quickly after the security researchers presented the decryptor for its all previous variants,[1] including one of the most prevalent one 5.1. The virus has been one of the most prominent threats in the wild, infecting users by using phishing emails, exploit kits, fake updates, and other distribution methods.

The virus employs a secure encryption algorithm to lock files and then demands a ransom to be paid in their return. The personal data that is marked with .[random] file extension is also accompanied by a ransom note [random]-DECRYPT.txt file, that is populated into each of the affected folders. This version of the virus appears to have changed slightly, with minor differences in ransom size ($550 in Dash or BTC) and payment instructions via the Tor browser.

Name GandCrab 5.2
Type Cryptovirus/ransomware
Family GandCrab
Extension Random 5-10 characters
Ransom size $550 in Dash or BTC (might vary)
Ransom note [random]-DECRYPT.txt
Distribution Spam email attachments, exploit kits, brute-force attacks, etc.
Decryption Decryption tool is available for this virus version
Elimination & system fix We recommend performing ransomware removal using anti-malware software and then clean the virus damage with ReimageIntego

Within the few days of GandCrab 5.2 discovery, malware researchers reported more than ten samples uploaded by victims[2]. Despite the newest malware strain being actively distributed, researchers noticed that V5.1 is still being delivered with the help of Fallout EK. For a long time, there was no decryption tool for the 5.2 version. However, Bitdefender has finally released a decrypter for this version also.

It appears that ransomware developers were focusing on releasing the new version as soon as possible, so all the previously known features were kept in development of the V5.2 variant:

  • the file extension placed at the end of encrypted data is formed from 5-10 random characters;
  • the ransom message gets delivered after the encryption process and appears on the Desktop wallpaper;
  • the note reveals payment methods and is also named according to the file appendix;
  • [random]-DECRYPT.txt ransom note encourages victims to pay up using TOR browser links, so there are no contact emails.

[random]-DECRYPT.txt is the pattern of a ransom note which is delivered by ransomware after a successful file locking process and reads the following:

—= GANDCRAB V5.2 =—

GandCrab 5.2 ransomwareGandCrab 5.2 ransomware is the most recent version in the notorious Gandcrab family that has all features of the previous virus.

The newest 5.2 release was discovered by Tamas Boczan – malware researcher who reported about it on Twitter and included ten malware samples and his analysis.[3]

Experts[4] recommend using automatic malware removal tools and employ ReimageIntego for the job, although other tools like SpyHunter 5Combo Cleaner can be used as well. This variant of malware is detected under various names, including:

  • TR/AD.GandCrab.tvnwv
  • Win32:Malware-gen
  • RDN/Generic.grp
  • Trojan:Win32/Dynamer!rfn
  • Ransom.GandCrab, etc.

According to the text file, you should go to the TOR browser[5] and launch the payment website. When this is done, you will be able to view a browser window containing instructions and the ransom size. As previous members in this family, the 5.2 version demands to pay in DASH or Bitcoin cryptocurrency.

Gandcrab 5.2 threat5.2 version of the notorious virus can be decrypted with the help of Bitdefender decryptor

However, the amount may differ according to the number of encrypted files, victim origin, and other factors. The demanded payment can reach $2,400, although some users reported that this version asks for $550. Although cybercriminals promise free decryption of one file and even guarantee the full data decryption, later on, these people are cybercriminals and cannot be trusted regardless. The main focus of virus developers is your money.

Make sure that you remove GandCrab 5.2 instead of paying the ransom or contacting these criminals because it is not advisable, especially, when cybercriminals are known for their malicious behavior for a while. Your concern about the encrypted data is understandable, but you need to focus on the malware termination first as locked files can only be restored after the cyber threat is terminated from the infected Windows computer system.

Spam email attachments hide infected files that execute ransomware payload

While browsing the internet, you will get alerts when you encounter phishing or malware-laden sites if you have reputable anti-malware employed. However, when it comes to spam email, you cannot be sure that the email is not safe without checking it manually. It is possible to scan the attached file before opening the document on the system and make sure that its purpose is not malicious.

Unfortunately, when you are not doing so, you can easily get malware infections from the PDF or Word attachment when you download and open the file on your device without checking. These emails often include names of well-known services or companies to trick people more. When the malicious script gets triggered direct ransomware payload, or other malicious programs get on your system without any interruption.

Clear the system from GandCrab 5.2

You need to start ransomware removal as soon as you notice the activity of this virus or any other suspicious behavior. It can be done easily if you use professional anti-malware programs. These automatic tools can perform a full system scan and indicate possibly malicious programs immediately.

Gandcrab 5.2 virusSecurity software can easily stop even the newest versions of the virus

After the thorough system scan, ReimageIntego, SpyHunter 5Combo Cleaner or Malwarebytes suggests methods to remove the virus and clean the PC. You should follow those steps and terminate the virus including virus damage. Repeat the scan with another similar program and double-check before entering an external device with backups or installing the data recovery software.

5.2 is the most recent version in this particular family, and there was no official decryption tool developed for a long time until now. Check the data recovery methods that are provided at the end of this article and you will also find the Bitdefender's decrypter that has been released not so long ago.

How to prevent from getting ransomware

Access your website securely from any location

When you work on the domain, site, blog, or different project that requires constant management, content creation, or coding, you may need to connect to the server and content management service more often. The best solution for creating a tighter network could be a dedicated/fixed IP address.

If you make your IP address static and set to your device, you can connect to the CMS from any location and do not create any additional issues for the server or network manager that needs to monitor connections and activities. VPN software providers like Private Internet Access can help you with such settings and offer the option to control the online reputation and manage projects easily from any part of the world.

 

Recover files after data-affecting malware attacks

While much of the data can be accidentally deleted due to various reasons, malware is one of the main culprits that can cause loss of pictures, documents, videos, and other important files. More serious malware infections lead to significant data loss when your documents, system files, and images get encrypted. In particular, ransomware is is a type of malware that focuses on such functions, so your files become useless without an ability to access them.

Even though there is little to no possibility to recover after file-locking threats, some applications have features for data recovery in the system. In some cases, Data Recovery Pro can also help to recover at least some portion of your data after data-locking virus infection or general cyber infection.
