The Justice Department announced Tuesday its largest-ever financial seizure — more than $3.6 billion — and the arrests of a New York couple accused of conspiring to launder billions of dollars in cryptocurrency stolen from the 2016 hack of a virtual currency exchange.

Federal law enforcement officials said the recovered sum was linked to the hack of Bitfinex, a virtual currency exchange whose systems were breached by hackers nearly six years ago.
