An anonymous -- and controversial -- researcher surreptitiously tested trillions of Internet addresses over the past nine months. The hacker found that all sorts of devices are protected only by the easy-to-guess default passwords that the equipment came with when new, according to the BBC.

Chester Wisniewski, with the computer security firm Sophos, joins Marketplace Tech host David Brancaccio to explain what this means for global Internet security.
