The New Zealand researcher whose 2010 Black Hat talk 'Jackpotting Automated Teller Machines' made two ATMs spray cash across the stage on command - the single most-cited demonstration in conference history, and the origin of jackpotting as a term.
He went on to show that insulin pumps could be commanded from hundreds of feet away and that implantable defibrillators could be made to deliver a lethal shock - work that pushed medical-device security into regulation and reportedly influenced how the US Vice President's own device was configured. He died in 2013, days before a DEF CON talk on pacemakers, at thirty-five. The showmanship was the method: he proved that a stage demo moves an industry that a hundred advisories cannot.
