ewhac writes "The San Francisco Chronicle is reporting that computer security researchers throughout the University of California system managed to crack the security on every voting machine they tested that has been approved for use in the state. The researchers are unwilling to say how vulnerable the machines are, as the tests were conducted in an environment highly advantageous to the testers. They had complete access to the devices' source code and unlimited time to try and crack the machines. No malicious code was found in any of the machines, but Matt Bishop, who led the team from UC Davis, was surprised by the weakness of the security measures employed. The tests were ordered by Secretary of State Debra Bowen, who has until Friday of next week to decide whether to decertify any of the machines for use in the upcoming Presidential primary election."
