GANDCRAB 5.0.1 – Distribution Methods
The latest iteration of GANDCRAB ransomware does not cheat on the old method of being replicated. The malware may infect via comromised websites, the main idea behind which is to pretend that the program you are looking for online has a crack that is available for download. This fake WordPress download site URLs is become more and more common practice as we have detected over recent months. Here is how a fake crack URL from the previous GandCrab version appears like when you look for the cracks for several converters, system tools and other types of seemingly useful programs:
The full list of programs that are imitated by the GandCrab can be seen on the related story underneath:

But this is not the only main source of propagation used by GandCrab 5.0.1 ransomware, since the virus may also be spread via the most widely used method for spreading ransomware viruses and that is via e-mail spam messages. The previous GandCrab iteration often used spam e-mails that carried around malicious e-mail attachments, also known as malspam. This type of activity was used to trick the victims into clicking on “I am not a robot” after downloading a PDF file and then this results in a Microsoft Word file that opens up with malicious Macros. The e-mails may appear like the following:
From: “Brandon Clay” Brandon@cdkconstruction.org
Subject: Electricity bill Feb-6509
Attachment: Feb-10451.pdf
Body Text: Download the attached file.
The .PDF file may show the following after being opened:
After this, the user is misled to click on “Enable Content” on a new Microsoft Word file that derives from the .PDF file and after this is done, GANDCRAB may trigger the infection:

The ransom note then leads the victim to visit a Tor-based web page, which is similar to the other GandCrab versions, appearing like the image below shows:
To make sure that the victim does not miss out on the notification, GANDCRAB 5.0.1 also sets the wallpaper to the following:
In addition to making sure the victim knows of it’s presence, GANDCRAB 5.0.1 does way more than just that. The virus may also perform other activities on the user PC, such as adding registry values in many Windows registry sub-keys. So far, GANDCRAB 5.0.1 is reported to access the following sub-keys in the Windows Registry database:
→ HKEY_CURRENT_USER\Control Panel\International
HKEY_CURRENT_USER\SOFTWARE\keys_data\data
HKEY_LOCAL_MACHINE\HARDWARE\DESCRIPTION\System\CentralProcessor\0
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Wbem\CIMOM
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion
HKEY_LOCAL_MACHINE\SOFTWARE\ex_data\data
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\Tcpip\Parameters
The GANDCRAB 5.0.1 also creates the following mutexes on the infected computer:
→ Global\8A5BA8BEE36925045F5C.lock
Global\XIAKFoxSKGOfSGOoSFOOFNOLPE
But the main indicators of compromise are the connections which are made by this iteration of GandCrab ransomware, which are reported at VMRay to be the following IP addresses:
GANDCRAB 5.0.1 Ransomware – Encryption Process
The 5.0.1 version of GANDCRAB ransomware virus is believed to utilize the Salsa20 encryption algorithm. Unlike the previous versions of GandCrab, this encryption mode is much faster in its encryption process so that it is more difficult to be halted. The GANDCRAB ransomware may perform the infection process in the following chronological steps:
Step 1: The virus scans the computer for the files it wants encrypted. Usually those files are:
- Documents.
- Videos.
- Audio files.
- Images.
- Archives.
- Databases.
- The virus skips scanning in important Windows directories, which may result in breaking your OS.
Step 2: GANDCRAB V5.0.1 then encrypts the files by first creating copies of the files and then encrypting the copies after which the ransomware virus may delete the original files.
Step 3: After the encryption process has finished, the ransomware virus creates a unique decryption key that is concealed and may have either the .KEY or the .lock extension. The file itself may also be encrypted and cannot be opened.
Step 4: The GANDCRAB 5.0.1 ransomware adds a random 5 letter extension to the encrypted files, making them to start appearing like the following:
Step 5: The GANDCRAB 5.0.1 malware likely hides it’s tracks by deleting any backups and shadow copies it might encounter. This happens by executing the following commands in Windows Command Prompt as an administrator:
→ sc stop VVS
sc stop wscsvc
sc stop WinDefend
sc stop wuauserv
sc stop BITS
sc stop ERSvc
sc stop WerSvc
cmd.exe /C bcdedit /set {default} recoveryenabled No
cmd.exe /C bcdedit /set {default} bootstatuspolicy ignoreallfailures
C:\Windows\System32\cmd.exe” /C vssadmin.exe Delete Shadows /All /Quiet

If you have become a victim of the 5.0.1 iteration of GANDCRAB ransomware, then you have three choices – to pay the ransom and hope for the best (not recommended), to pay a lot of money to a file recovery expert or to follow the instructions underneath this article and remove the virus yourself. The instructions below have been divided in manual and automatic removal methods. If manual removal does fail, then be advised that most experts would run a scan, using a specific anti-malware software. Such programs are usually designed to fully detect and remove all files and objects otherwise difficult to spot manually and in the same time they aim to protect your PC against any threats that might appear in the future too.
If your files were encrypted and you have no idea how to get them back, then we strongly suggest that you refrain from paying ransom to the cyber-crooks behind GANDCRAB 5.0.1. Doing this is not a guarantee that they will decrypt your files afterwards. Do not despair, however, because you still haven’t ran out of options. We have summed up several alternative recovery methods that you can try below in the step “2. Try to restore files, encrypted by GANDCRAB 5.0.1”. They are not a 100% guarantee of successful file recovery, but with their assistance, you can restore some or most of your files, depending on your situation.
