For over 25 years, hackers, spies, cops, Silicon Valley-types, technologists, and even politicians descend upon Las Vegas, Nevada for what’s become the pre-eminent hacker conference in the world: Def Con.

For cyber journalists, the conference is a nonstop source-fest and social circuit that takes place in a blur of various casinos and hotels blaring top-40 hits. It’s also been the site of high profile arrests of hackers such as Dmitriy Skylarov in 2001, or Marcus Hitchins (AKA ‘MalwareTech’), who stoppedWannaCry in its tracks before being scooped up by the FBI in 2017.
