During a security test of Diebold voting machines in Leon County, Florida, Finnish security expert Harri Hursti demonstrated the ease with which Diebold voting machines could be hacked. In a test election where the results should have been yes: 2, no: 6, Hursti got the machine to read yes: 7, no: 1.

The method used required only a moderate level of inside access, and was accomplished without being given any password and with the same level of access given thousands of poll workers across the USA. It changed votes in a one-step process that could not be detected in any normal canvassing procedure, it required only a single a credit-card sized memory card, any single individual with access to the memory cards could do it, and it required only a small piece of equipment which can be purchased off the Internet for a few hundred dollars.

Leon County supervisor of elections Ion Sancho has announced that he will never again use Diebold in an election.
