A major new report on electronic voting has concluded that the three most common types of electronic voting machines are all vulnerable to software attacks. The study by the Brennan Center for Justice concluded that a single person with technical knowledge could alter the outcome of an election by tampering with the software. The study is considered the most comprehensive ever done on electronic voting machines. The report calls for electronic voting machines to produce voter-verifiable paper records, a ban on wireless components on all voting machines, new safeguards to detect software attacks, as well as routine audits.
