Blackbox Voting reports numerous ways to hack a Diebold optical scan machine

“1. An altered memory card (electronic ballot box) was substituted for a real one. The optical scan machine performed seamlessly, issuing a report that looked like the real thing. No checksum captured the change in the executable program Diebold designed into the memory card.

2. A second altered memory card was demonstrated, using a program that was shorter than the original. It still worked, showing that there is also no check for the number of bytes in the program.

3. A third altered memory card was demonstrated with the votes themselves changed, showing that the data block (votes) can be altered without triggering any error message.”
