Detects network connection activity originating from QEMU virtualization processes (qemu-system-x86_64, qemu-system-i386, qemu-system-aarch64) to external (non-private/non-local) IP ranges. This could indicate the use of virtualization tools to facilitate tunneling, proxying, or lateral movement within an environment.
