Qilin EDR killer infection chain

This report analyzes a malicious msimg32.dll loader observed in Qilin ransomware attacks that implements a multi-stage in-memory PE loader and deploys an EDR-killer capable of disabling over 300 EDR drivers; it details SEH/VEH-based control-flow obfuscation, syscall bypass techniques, use of abused signed drivers for physical memory access, helper drivers to terminate protected processes, and provides hashes and IOCs for detection.
