QEMU Toolkit Deployment via ScreenConnect Files Directory (qemu_custom.zip)
Detects suspicious use of QEMU virtualization software within an environment, specifically when associated with ConnectWise ScreenConnect. This includes the creation of custom QEMU image files within the ScreenConnect Files directory, the execution of the QEMU binary using those images, the extraction of QEMU archives using 7-Zip, or instances where ScreenConnect processes spawn the QEMU binary directly. This pattern is indicative of unauthorized use of virtual machines to facilitate persistence, lateral movement, or tool staging.
