Electronic warfare, signal jamming, hacking, phreaking, and crypto are not new to anyone in the military, and most certainly not the intelligence community. The Allies won WWII on the strength of their signals intelligence.

There's the potential for the "bad guys" to do more here, using automated agents provocateur, but that's really nothing new - We had Japanese internment camps because of fears of that, and we certainly don't want that again. Imagine what would happen if we booted every windows machine off the internet for a day... Maybe we should relive those internment camps, after all :)
