Changpeng Zhao (CZ) said AI is increasing the speed of cyberattacks beyond financial institutions' ability to improve defenses. Bitcoin.com News reported that CZ spoke publicly for the first time since Binance suffered a $6.3 billion attack on October 29. The FBI attributed the attack to hackers from North Korea. CZ backed a crypto industry security alliance and said Binance and the wider industry have invested too little in security. CZ said Binance's decision to cover all losses and quickly confirm that user funds were safe limited wider market disruption.
