In May 2017, Hutchins was hailed as a hero after playing a pivotal role in stopping the global spread of the WannaCry ransomware attack. That heroic status was tarnished when, as he travelled home following the Black Hat and Def Con security conferences, Hutchins was arrested by the FBI at the Las Vegas McCarran International Airport.
