Security Analysis of the Diebold AccuVote-TS Voting Machine. These voting machines are even more broken than you think. Ars Technia has posted nice summary of this article. The research was done in part by Professor Ed Felten who writes for the Freedom to Tinker web site, which is well worth reading.

E-voting systems hacker sees ‘particularly bad’ security issues ...On Tuesday, Dec. 13, we conducted a hack of the Diebold AccuVote optical scan device. I wrote a five-line script in Visual Basic that would allow you to go into the central tabulator and change any vote total you wanted, leaving no logs.... More from the Washington Post here, where ... Four times over the past year Sancho told computer specialists to break in to his voting system. And on all four occasions they did, changing results with what the specialists described as relatively unsophisticated hacking techniques. ..."Can the votes of this Diebold system be hacked using the memory card?" Two people marked yes on their ballots, and six no. The optical scan machine read the ballots, and the data were transmitted to a final tabulator. The result? Seven yes, one no. ... Verified Voting and Black Box Voting have much much more on all of this.

"If voting could really change things, it would be illegal." More fun from Diebold: on Tuesday, two PA-based student groups announced they will engage in "electronic civil disobedience" by ignoring Diebold's demands to remove public access to leaked memos from Diebold offices, which indicate among other things "...that Diebold, which counts the votes in 37 states, knowingly created an electronic system which allows anyone with access to the machines to add and delete votes without detection."

Are our elections fixed? Diebold Election Systems makes electronic voting machines being installed throughout the US. The problem? The systems contain serious security flaws that could possibly have been the reason for major swings in vote counts and discrepancies with exit polling. Also, a step-by-step guide to manipulating Diebold results -- and covering your tracks.
