Some of you may remember this forum post from 2010 about a University of Michigan research team that successfully hacked a Washington, D.C. e-voting trial after D.C.'s Board of Elections and Ethics opened it for testing. That team, led by professor J. Alex Halderman, has now published a paper on the attack, and it's much more impressive/funny/frightening than initially reported.
The news articles at the time reported that they had hacked the system to play "The Victors" after a vote was cast - but that was only the first sign of infiltration. They also managed to add an "OWNED" picture to the logout page, discover the authentication codes for every DC voter, and modify every ballot to be write-ins for fictional computers and robots. (Bender beat Skynet for head of the school board.)
