In a series of four tests conducted in Feb., May, and Dec. 2005, Ion Sancho invited Black Box Voting to Tallahassee after an invitation to check the Diebold machines. Black Box Voting engaged the services of Dr. Herbert Hugh Thompson and Harri Hursti. Dr. Thompson and Hursti believed they could change or hack vote totals without the system detecting entry. The first two projects targeted the computer program that adds up all the voting machine results and produces the final report. On Feb. 14 and again on May 2, Thompson successfully hacked the Diebold GEMS central tabulator and bypassed all passwords by using a Visual Basic script. This, however, would be detected in a vigilant environment if the supervisor of elections checks the poll tapes (voting machine results) against the central tabulator report.
