Can/will this method be used by hackers? What would they need to do to take advantage of that vulnerability?
EDIT: typo
Could be a hostile government sponsored group or idealists (Microsoft has more haters than fans) or simply someone could do it just because they can - if they could. Some men just want to see the world burn.
Im not sure you have a grasp of what actually happened.
They could also DDOS essentially anything with root access to that many devices.
Its like taking all the armies guns to throw them in a volcano ‘cause you want to see the world burn’
