An anonymous reader tips news of a vulnerability discovered in the Diebold Accuvote voting system, which could be used to alter voting results without leaving evidence of tampering. Quoting Salon: "[T]he Argonne team's attack required no modification, reprogramming, or even knowledge, of the voting machine's proprietary source code. ... The team's video demonstrates how inserting the inexpensive electronic device into the voting machine can offer a "bad guy" virtually complete control over the machine. A cheap remote control unit can enable access to the voting machine from up to half a mile away. ... The video shows three different types of attack, each demonstrating how the intrusion developed by the team allows them to take complete control of the Diebold touch-screen voting machine. They were able to demonstrate a similar attack on a DRE system made by Sequoia Voting Systems as well."
