Kim Jong Un's Sister Denies North Korea's Role in $6.3 Billion Binance Hack Kim Yo Jong, sister of North Korean leader Kim Jong Un, denied Pyongyang's involvement in the $6.3 billion hack of Binance, the world's largest cryptocurrency exchange, calling the FBI's accusations "absurd rhetoric" and a "grave political provocation," according to state media KCNA. The FBI previously attributed the October 29 attack to North Korean hacking group TraderTraitor, saying the stolen assets were being converted primarily into ETH and could be further laundered through DeFi platforms and instant swap services. U.S. authorities have urged crypto exchanges and other service providers to block transactions linked to the stolen funds.
