Introduction

MARK ransomware is a variant within the Makop family, known for encrypting files and appending a distinctive extension that includes the victim’s ID and an attacker-controlled email address. This ransomware changes the desktop wallpaper and drops a ransom note titled “+README-WARNING+.txt” to inform victims of the encryption and demand payment.

Technical Overview

File Encryption Process

Upon execution, MARK ransomware encrypts files using the AES-256 algorithm. Encrypted files are renamed to include the victim’s unique ID and the attacker’s email address, followed by the “.MARK” extension. For example, “1.jpg” becomes “1.jpg.[2AF20FA3].[[email protected]].MARK”.
