John Draper, a legendary figure in the world of pre-digital phone hacking known as "phreaking," has been publicly accused of inappropriate sexual behavior going back nearly two decades.
According to a new Friday report by BuzzFeed News, Draper, who is also known as "Captain Crunch," acted inappropriately with six adult men and minors between 1999 and 2007 during so-called "energy" exercises, which sometimes resulted in private invitations to his hotel room. There, Draper allegedly made unwanted sexual advances.
As a result of the new revelations, Draper, 74, is now no longer welcome at Defcon. Michael Farnum, the founder of HOU.SEC.CON, told Ars on Friday afternoon that Draper, who had been scheduled to speak in April 2018, was disinvited.
