It's impossible for a single maintenance computer to move $6.3 billion. Even if CZ (@cz_binance) came, he'd probably struggle. On-chain analytics firm TRM deduces that the private key wasn't lost, but the hacker gained the ability to have Binance's hot wallet signing system sign on its behalf, which allowed funds to be transferred from multiple wallets across different chains within about half an hour. This person/team must be very familiar with Binance's entire internal operational process. TRM also highly believes it's a North Korean TraderTraitor, the same group that stole $1.5 billion from Bybit last year. It seems that from now on, major project teams/DEXs/CEXs will definitely have to use "Golden XX is XX" as a background check sworn statement when recruiting. Binance says withdrawals are expected to resume within 48 hours. Please wait for the official announcement.
