About a quarter of a century ago, a handful of hackers decided to have a party in a cheap hotel, and had a whale of a time. Fast forward to 2018, and that get-together has grown into events that will see an estimated 30,000 people converge on Las Vegas for the biggest security shindig in the world — the combination of Black Hat USA, DEF CON and BSidesLV. From a report: While that first gathering morphed into the DEF CON hacking conference, the biggest event is Black Hat USA, which began on Saturday, and runs through until Thursday, August 9. This is the flashy corporate brother of DEF CON, and features four days of security training, a one-day invite-only CISO summit day (from which press are strictly barred) and two days of briefings featuring everything from government agents to hardcore hackers talking about the tricks of the trade. Although they have a shared origin — DEF CON founder Jeff Moss also set up Black Hat USA — these days, DEF CON and Black Hat USA are run and operated separately. We’ve previously described the behind-the-scenes and arduous task of setting up and maintaining computer networks for attendees of hacker conventions.
