Internet reports that according to an FBI announcement, the FBI issued a Security Announcement (PSA) confirming that the North Korean hacker group was responsible for the theft of approximately US$1.5 billion in digital assets on the Bybit Exchange. The FBI said the hacker group acted quickly and had converted some of the stolen assets into Bitcoin and other digital assets and dispersed them to thousands of addresses on multiple blockchains. These assets are expected to be further laundered and eventually converted into legal tender. To stop the circulation of stolen assets, the FBI specifically urged various participants in the cryptocurrency ecosystem to take action, including RPC node operators, exchange platforms, cross-chain bridge services, blockchain analytics companies, decentralized financial services and other virtual asset service providers to fully block all transactions related to or originating from addresses used by hackers to launder money.
