Researcher Demonstrates Stuxnet At Work

We know Stuxnet has caused some major disruptions in nations like Iran and India. But how, exactly, does it work? In this video, Symantec researcher Liam O'Murchu demonstrates how a Stuxnet infected programmable logic controller (PLC) by Siemens can instruct a piece of machinery to run out of control.

O'Murchu demonstrated the proof of concept by hooking the PLC up to an air pump which was programmed to lightly inflate a balloon. After being infected, the pump runs out of control, bursting the confetti filled balloon to applause from the audience of virus researchers gathered at the annual Virus Bulletin conference in Vancouver, Canada.
