US e-voting system cracked in less than 48 hours
Researchers at the University of Michigan have reported that it took them only a short time to break through the security functions of a pilot project for online voting in Washington, D.C. "Within 48 hours of the system going live, we had gained near complete control of the election server", the researchers wrote in a paperPDF that has now been released. "We successfully changed every vote and revealed almost every secret ballot." The hack was only discovered after about two business days – and most likely only because the intruders left a visible trail on purpose.
