Hackers at the Las Vegas' annual DEF CON event took over electronic voting machines in a display of a simulation run for the White House proving that rigging an election is indeed possible, something that many researchers have warned about for several years.

It took under 90 minutes for hackers to physically break down the 30 voting machines and discover weaknesses in their defenses, The Register UK reported.

Of the 30 voting booths, the hardware and software were manufactured by Diebold, Sequoia and Winvote.

Hackers proved the low level of security that voting machines have had which has been known for years; even a former Diebold contractor whistleblower, Chris Hood, told of the weakness of security and how easily voting machines can be exploited.
