Report: Diebold Opti-Scan Voting Machines Easily Hackable
Missed this last week, but Black Box Voting reports that the Diebold version 1.94 opti-scan voting system is easily hackable (Optical Scan System Hacked (3 Ways)).
Integer overflow checks do not seem to exist in this system, making it possible to stuff the ballot box without triggering any error message. This would be like pre-loading minus 100 votes for Tom and plus 100 votes for Rick (-100+100=ZERO) -- changing the candidate totals without changing the overall number of votes.
The opti-scan system is used in some 800 jurisdictions, though it is unclear which are using version 1.94. I've been unable to locate any response from Diebold.

This is absolute proof finally, but how on earth can this information get "out there"?
