Frequently Asked Questions
Threat Details: MortalKombat Ransomware
What is the MortalKombat ransomware and how does it operate?
MortalKombat is a Xorist ransomware variant first discovered in January 2023. It is named after the popular fighting video game and features a ransom note/wallpaper with art from the franchise. The ransomware is typically delivered via a malicious ZIP email attachment containing a BAT loader script. This script downloads a second archive from a remote resource, executes one of two malware payloads, and deletes the files to minimize detection. MortalKombat targets system files and applications, corrupts system folders like the Recycle Bin, disables the Windows Run command, and removes entries from Windows startup and the HKEY_CLASSES_ROOT registry hive, making affected applications non-functional.
Which regions have been targeted by the MortalKombat ransomware attacks?
The MortalKombat ransomware attacks have primarily targeted systems in the United States, with additional victims reported in the UK, Turkey, and the Philippines, according to Talos researchers.
How does the MortalKombat ransomware achieve persistence on infected systems?
The ransomware creates a Run registry key ("Alcmeter") for persistence and deletes the installed application's root registry key in the HKEY_CLASSES_ROOT registry hive, which disrupts file associations and application functionality.
What ransom instructions are provided to victims of MortalKombat ransomware?
The ransom note, displayed as a wallpaper, instructs victims to use the qTOX Tor-based instant messaging app to negotiate with the attackers, who demand payment in Bitcoin. A ProtonMail email address is also provided if victims have trouble registering on qTOX.
Does MortalKombat ransomware include wiper functionality?
No, MortalKombat does not feature wiper functionality. However, it corrupts system folders such as the Recycle Bin, disables the Windows Run command, and removes entries from Windows startup, making file recovery difficult.
How does MortalKombat ransomware affect Windows registry settings?
MortalKombat ransomware creates a Run registry key for persistence and deletes the installed application's root registry key in the HKEY_CLASSES_ROOT hive, which stores information about file associations and commands. This action can render applications non-functional.
What makes MortalKombat ransomware less sophisticated than other ransomware?
Talos analysts report that MortalKombat is not very sophisticated because it targets system files and applications, which are commonly avoided by more advanced ransomware to prevent system instability.
How is MortalKombat ransomware delivered to victims?
The ransomware is delivered via email containing a malicious ZIP attachment. This ZIP file contains a BAT loader script that, when executed, downloads a second archive with the malware payloads from a remote resource.
What happens to files and applications after a MortalKombat ransomware attack?
After infection, the ransomware corrupts system folders like the Recycle Bin, disables the Windows Run command, removes startup entries, and deletes registry keys, making it difficult to recover files or run affected applications.
What is the significance of the HKEY_CLASSES_ROOT registry hive in MortalKombat ransomware attacks?
The HKEY_CLASSES_ROOT registry hive stores information about file associations, commands, and icons for each file type. By deleting entries from this hive, MortalKombat ransomware prevents applications from functioning properly.
