Re: this going to go well
At least no-one will actually die, just spend the rest of their lives in legal disputes as the mess gets cleared up. oh... was that a hospital system I just wiped?
Some interesting scenarii to consider: find a poorly secured account on the, say, DoJ systems, log in there and use that to chuck whatever mildly worrying connections at a NSA subsystem.
Interesting side effect: as most people in charge have a very hazy understanding of "hacking", care to imagine what absolute mess would be achievable... heck, some network testing tools allow you to spoof the originating IP out of the box, no actual hacking needed...
I will say no more lest it gives Anonymous some "interesting" ideas.
