The fresh deployment comes after North Korea suffered heavy casualties on the front lines in Russia’s war against Ukraine, the South’s spy agency says.

South Korea’s spy agency says North Korea appears to have sent additional troops to Russia, after its soldiers deployed on the Russian-Ukraine fronts suffered heavy casualties.

North Korean hackers were behind the theft of $1.5 billion of virtual assets last week from Dubai-based cryptocurrency exchange Bybit, the U.S. Federal Bureau of Investigation said, marking the biggest heist in history.

Assets were stolen from Dubai-based cryptocurrency exchange Bybit earlier this month, in what's believed to be the largest-ever digital heist.

The FBI has officially linked the $1.4 billion cryptocurrency heist at Bybit to North Korean state-sponsored hackers after security researchers reached the same conclusion. The agency alleges that the infamous North Korean hacking group Lazarus is behind the hack.
