Marcus Hutchins, the unassuming Brit who found and activated the kill switch in the WannaCry ransomware, has been arrested by the FBI in America.

Hutchins had been invited over to the States for the DEF CON hacking conference, held last week in Las Vegas, Nevada, and stayed on a few extra days to do the usual touristy things in the area. He attended various parties at the event, went shooting, as is somewhat traditional, and had been planning to return home yesterday.
