Detects the execution of QEMU binary components (qemu-system-x86_64.exe, etc.) on Windows hosts when spawned by suspicious parent processes or with command-line arguments indicative of VM disk image handling or non-interactive execution. This behavior is used by threat actors to execute malicious payloads within a virtualized container to evade host-based EDR monitoring and security controls.
