I remember back in 2014, just before annexing Crimea, Russian operatives managed to shut off the power to the Ukrainian army's headquarters in Crimea, leading to a lot of confusion and inability to communicate (they had to use mobile phones). I think what's more likely, and more useful, is to somehow isolate Ukraine itself from the rest of the world (instead of just Twitter), so that the news of the invasion could not spread outside. Although in either case you still can't do much about satellite images.
