If BTC is also lost, then the situation at Binance is far more complex than what has been publicly stated: I initially thought that Binance was only hacked at Ethereum's hot wallet #14—that the server for hot wallet #14 was compromised, and then the 7702 protocol was used to authorize the wallet's data, leading to its emptying. The hacking path to the server responsible for signing was: first, hacking a maintenance Mac computer (although this is highly unlikely). However, in recent days, people have been saying that BTC and TRX were also stolen, which is a much more serious matter, and it's no longer just about hot wallet #14. Because the BTC hot wallet system and signing system are not on the same server as hot wallet #14; they are all independent servers. Clearly, the hacker didn't obtain the private key. Therefore, the BTC theft likely used Bitget's simulated withdrawal method, a method recently used, which Binance couldn't have been unprepared for. Adding to this, the Tron chain was also hacked, meaning this isn't just a matter of one server being compromised; this is a complete breach of Binance's wallet server cluster! If BTC and TRX were indeed stolen, then Binance hasn't been honest, and the problem could be much more serious than just money!
