GANDCRAB v5.0.2 is a cryptovirus belonging to the infamous GandCrab Ransomware family. The virus encrypts your files and demands money as a ransom to get your files restored. Files receive a random 10-letter extension. The first part of the name of the ransom note is formed by that extension in capital letters, so as an example the note with instructions would be called DGDLLEFZTK-DECRYPT.txt. Notice that it is a .txt file instead of a .html one. A wallpaper picture serves as a complimentary ransom message as previous versions include it, too. Keep on reading the article and see how you could try to potentially recover some of your locked files.

GANDCRAB 5.0.2 – Update November 2018

A secondary attack featuring the GandCrab 5.0.2 ransomware has been found in a DLL payload. This is the standard file format used for application and system libraries — essential code that is necessary in order for them to function properly. The fact that it has been found in this form shows that the virus strains can be found in archives, installers and downloads. The dropper itself has several important capabilities that are launched before the final virus is delivered:

  • Anti-Analysis Module — This function will detect whether or not the virus is run under a virtual machine host. If this is the case it will delete itself in order to avoid detection.
  • Persistence — The infection engine will be started every time the computer is accessed or the relevant application is opened.
  • Windows Modification — The GandCrab 5.0.2 payload dropper will install a hacker-made security certificate into the system which will allow the malicious threat to obtain administrative privileges and completely take over the system.

GANDCRAB v5.0.2 Virus – Distribution Techniques

The GANDCRAB v5.0.2 ransomware might distribute itself via different techniques. A payload dropper which initiates the malicious script for this ransomware is being spread around the World Wide Web, and researchers have gotten their hands on a malware sample. If that file lands on your computer system and you somehow execute it – your computer device will become infected.

Below, you can see the payload file of the cryptovirus being detected by the VirusTotal service:

Freeware which is found on the Web can be presented as helpful also be hiding the malicious script for the cryptovirus. Refrain from opening files right after you have downloaded them. You should first scan them with a security tool, while also checking their size and signatures for anything that seems out of the ordinary. You should read the tips for preventing ransomware located at the corresponding forum thread.

GANDCRAB v5.0.2 Virus – In-Depth Analysis

GANDCRAB v5.0.2 is a virus that encrypts your files and leaves a ransom note, with instructions inside it, about the compromised computer device. The extortionists want you to pay a ransom fee for the alleged restoration of your files.

GANDCRAB 5.0.1 is said to use the CVE-2018-0896 Microsoft vulnerability. This information disclosure vulnerability is in the Windows kernel and could allow an attacker to retrieve information that could lead to a Kernel Address Space Layout Randomization (ASLR) bypass. An attacker could exploit the vulnerability if logged on to an affected system and runs a specially crafted application. That would result in the vulnerability being successfully exploited and thus leaving the hacker able to retrieve the memory address of a kernel object. If GANDCRAB 5.0.2 follows suit of its previous version, the same vulnerability might be exploited again.

GANDCRAB v5.0.2 ransomware makes various entries in the Windows Registry to achieve persistence, and could launch or repress processes in a Windows environment. Such entries are typically designed in a way to start the virus automatically with each boot of the Windows Operating System. Below you will see the list with registries that are tampered with:

→HKEY_CURRENT_USER\Control Panel\International
HKEY_CURRENT_USER\Control Panel\International\LocaleName
HKEY_CURRENT_USER\Keyboard Layout\Preload
HKEY_CURRENT_USER\Keyboard Layout\Preload\1
HKEY_CURRENT_USER\Keyboard Layout\Preload\2

After encryption the GANDCRAB v5.0.2 virus will save a ransom note. The first part of the name of that ransom note is formed by the extension in capital letters, so as an example the note with instructions would be called DGDLLEFZTK-DECRYPT.txt.

The ransom message has the following contents:

—= GANDCRAB V5.0.2 =—

The message above, displayed by the GANDCRAB v5.0.2 ransomware virus indicates that your files are encrypted. You are demanded to pay a ransom sum to allegedly restore your files. However, you should NOT under any circumstances pay any ransom sum. Your files may not get recovered, and nobody could give you a guarantee for that. Adding to that, giving money to cybercriminals will most likely motivate them to create more ransomware viruses or commit different criminal activities. That may even result to you getting your files encrypted all over again after payment.

Above you see a snapshot of the text that shows on your new Desktop wallpaper (considering that your computer got compromised).

The text states the following:

ENCRYPTED BY GANDCRAB 5.0.2
DEAR [user name] YOUR FILES ARE UNDER STRONG PROTECTION BY OUR SOFTWARE IN ORDER TO RESTORE IT YOU MUST BUY DECRYPTIOR
For further steps read [extension letters]-DECRYPT.txt that is located in every encrypted folder.

Judging from how fast GandCrab is spreading, it will not be surprising if we see a GANDCRAB v5.0.3 soon. The previous two variants of GandCrab are these:

GANDCRAB v5.0.2 Ransomware – Encryption Process

The encryption process of the GANDCRAB v5.0.2 ransomware rather simple – every file that gets encrypted will become simply unusable. Files will get an extension composed of 10 random letters. The newly added extension will be added as a secondary one, without changing the original extension.

A list with the targeted extensions of files which are sought to get encrypted is currently unknown. However, if the list becomes available, the article will get updated accordingly.

The files used most by users and which are probably encrypted are from the following categories:

  • Audio files
  • Video files
  • Document files
  • Image files
  • Backup files
  • Banking credentials, etc

The GANDCRAB v5.0.2 cryptovirus could be set to erase all the Shadow Volume Copies from the Windows operating system with the help of the following command:

→vssadmin.exe delete shadows /all /Quiet

In case the above-stated command is executed that will make the effects of the encryption process more efficient. That is due to the fact that the command eliminates one of the prominent ways to restore your data. If a computer device was infected with this ransomware and your files are locked, read on through to find out how you could potentially restore some files back to their normal state.
