The two satellites, Landsat-7 and Terra AM-1, had been interfered with on four separate occasions, allowing the attackers to be in command of the satellites for two to over twelve minutes each time.
Luckily, both of the satellites are used only for observing the Earth's climate and terrain, and the hackers never actually misused their control over them in any way. But the compromises have definitely been taken very seriously, since future targets could include satellites with more sensitive functions, such as those used by the U.S. military and the various intelligence agencies for reconnaissance and communication.
I read an article about the virus worm problems they are having at the Predator control center somewhere in Nevada I think. They keep deleting the virus but it re-emerges. Imagine losing control of a remote flying weapon? Lots of this going on, cyber warfare. Oh my!
