The Dutch computerised voting system is completely open to fraud, and bad guys could find out, remotely, how you voted. So argue Rop Gonggrijp and colleagues of the â€œWe do not trust voting computersâ€ foundation in The Netherlands. Gonggrijp and co are some of smartest hackers around, so we are sure they are right. A technical paper by Gonggrijp’s team details how they installed new software in Nedap ES3B voting computers. They established that anyone, when given brief access to the devices at any time before the election, could gain complete and virtually undetectable control over the election results. It also shows how radio emanations from an unmodified ES3B can be received at several meters distance and be used to tell who votes what. This is not a small crisis. 90% of the of votes cast in The Netherlands are cast on the Nedap/ Groenendaal ES3B voting computer – and it’s due to be used in a national election next month. The same computer with very minor modifications is also being used in parts of Germany and France.
