The Qilin ransomware campaign employs a malicious 'msimg32.dll' DLL as part of a multi-stage infection chain designed to disable endpoint detection and response (EDR) systems. The malware uses SEH/VEH-based obfuscation, kernel object manipulation, and API/system call bypass techniques to evade detection. It terminates over 300 EDR drivers from various vendors by loading helper drivers ('rwdrv.sys' and 'hlpdrv.sys') to suppress EDR monitoring and terminate processes.
