Binance founder Changpeng “CZ” Zhao said four data breaches had been reported, including contact-data exposure at Coinbase vendor Amplitude and a user-data breach at South Korean exchange Bithumb, according to BlockBeats. The flash said funds were unaffected in the Amplitude incident and also named Mirae Asset and Daishin Securities as affected South Korean securities firms.

CZ said leaked names, emails, phone numbers, addresses, identity documents and transaction records can be used for phishing, SIM swapping and social engineering. He urged users to limit the information shared across platforms and consider a separate email alias for each trading service.
