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:

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
