The FBI has accused North Korean-linked hackers of conducting one of the largest known thefts of cryptocurrency — worth some $1.5 billion — from a Dubai-based firm.

A major cryptocurrency exchange says it was the victim of a sophisticated hack that stole about $1.5 billion worth of digital currency, marking one of the biggest online thefts of all time.

A juvenile in Canton Township and six other men have been identified as members of “The Community,” an international group that hacks into people’s cellphones -- often bribing or tricking mobile phone companies -- to steal millions of dollars in Bitcoin and other cryptocurrency, officials said.
