Marcus Hutchins became an overnight hacker hero when he figured out a way to stop the WannaCry cyber attack from North Korea from continuing. The attack had crippled the British health care system and caused billions in losses across 150 countries. The notoriety gave him a huge amount of attention, both wanted and unwanted. When he came to Las Vegas, he didn’t realize a grand jury in Wisconsin had indicted him for creating Kronos, a virus that steals bank information and sells it to cybercriminals. Eventually, he was arrested, put under house arrest, and the FBI confiscated everything he owned.
