In his stunning public testimony --- before a single member of the D.C. Board of Ethics and Elections (BoEE), and a nearly empty chamber --- Halderman explained how the team had, by the time they discovered their fellow intruders, already gained complete control of the system, it's encryption key and its passwords. The system was developed as part of an Internet Voting pilot program with the Open Source Digital Voting Foundation.
As The BRAD BLOG reported last week, Halderman's team was able to take over the system within 36 hours after it had gone live for testing. After having "found and exploited a vulnerability that gave [them] almost total control of the server software," his team was able to steal the encryption key needed to decode "secret" ballots; overwrite every single ballot cast on the test system; change the votes on those ballots to write-in candidates; discover who had already been voted for and the identities of the voters; install a script that would automatically change all votes cast in the future on the same system; install a backdoor to allow them to come back later; and then leave a "calling card" --- the University of Michigan fight song --- which was programmed to play in the voter's browser 15 seconds after each Internet ballot had been cast.
