THE article discusses 'Mistic,' a stealthy backdoor used by the hacking group KongTuke, known for financially motivated ransomware attacks since April 2026. Mistic utilizes DLL sideloading, camouflaging itself as a legitimate Microsoft process to gain access while remaining unnoticed. It can connect to command-and-control servers for various functions, including file management and execution of code in memory, with a built-in self-delete feature for stealth.
The backdoor's deployment typically involves social engineering tactics and highlights a trend of using custom malware for covert operations in ransomware attacks. KongTuke demonstrates significant flexibility and skill in developing and deploying such tools, posing an ongoing threat.
