E-voting machines vulnerable to remote vote changing | InSecurity Complex - CNET News "The Vulnerability Assessment Team at Argonne Laboratory, which is a division of the Department of Energy, discovered this summer that Diebold touch-screen e-voting machines could be hijacked remotely, according to team leader Roger Johnston. Salon reported on it today, noting that as many as a quarter of American voters are expected to be using machines that are vulnerable to such attacks in the 2012 election. Basically, when a voter pushes a button to record his or her votes electronically, the remote hijacker could use a Radio Frequency remote control to intercept that communication, change the votes, and then submit the fraudulent votes for recording. The researchers uncovered similar problems with Sequoia e-voting systems in 2009, Johnston told CNET this afternoon. He said he believes the problem exists in all major e-voting systems but has only demonstrated successful attacks on the two systems."
