According to the FBI announcement, the US Federal Bureau of Investigation issued a security advisory (PSA), confirming that the North Korean hacker group was responsible for the theft of about $1.50 billion of digital assets from the Bybit exchange. The FBI said that the hacker group acted quickly and has converted some of the stolen assets into bitcoin and other digital assets, and dispersed them to thousands of addresses on multiple blockchains. It is expected that these assets will be further laundered and eventually converted into fiat currency. In order to stop the circulation of stolen assets, the FBI specifically urges various players in the cryptocurrency ecosystem, including RPC node operators, exchange platforms, cross-chain bridge services, blockchain analytics firms, decentralized financial services, and other virtual asset service providers, to fully block all transactions related to or originating from addresses that hackers use to launder money.
