The Security Group at
the University of California in Santa Barbara has released the
video that shows the attacks carried out against the Sequoia
voting system. I heard about the video when talking to some members of the
group, but it was never made available to the public before. The video was
shot as part of the Top-To-Bottom Review organized by the California Secretary
of State. Even though the review was carried our in July 2007, the video has
been posted only now, more than a year after (why?).
The video shows an attack where a virus-like software spreads across the
voting system. The coolest part of the video is the one that shows how the
"brainwashed" voting terminals can use different techniques to change the
votes even when a paper audit trail is used. Pretty scary stuff. The video is
proof that these types of attacks are indeed feasible and not just a
Also, the part that shows how the "tamperproof" seals can be completely
bypassed is very funny (and disturbing at the same time).
