Yes. The claim comes from Tree News posts forwarded on Telegram on Nov 1 around 05:28 UTC, wording it as FBI: North Korea was responsible for the theft of more than $6B in virtual assets from Binance, tagged RTRS / Reuters.

Those forwards are in BWEnews, Rickler Feed and other channels, in English and Chinese. No Reuters text itself was readable in the follows.

That is a step beyond what was on record Oct 30. Then Chainalysis and TRM Labs attributed the roughly $6.3-6.4B Oct 29 Binance drain to North Korea's TraderTraitor, and Reuters only reported Binance working with law enforcement including the FBI and Secret Service.

President Trump said Oct 30 the US was looking into the hack and, asked if North Korea did it, said "we don't know."

So answer the question as reported now: yes per Tree News citing Reuters, FBI attributes the $6B-plus Binance theft to North Korea. The underlying FBI statement was not independently verified in these reads.
