CZ: Four data breach incidents occurred today, and users should strengthen their account security protections

Odaily reports: Binance founder CZ posted on the X platform that four data breach incidents were reported today, involving Coinbase third-party service provider Amplitude, South Korean crypto exchange Bithumb, and South Korean traditional financial institutions Mirae Asset and Daishin Securities. Among them, the Amplitude security incident affected the contact information of some Coinbase users, but user funds were not affected.

CZ noted that information such as names, emails, phone numbers, addresses, identity documents, and transaction records leaked from trading platforms may be used for phishing, SIM-swapping, and social engineering attacks.

In response, CZ recommends that users set up separate email addresses and strong passwords for different trading platforms, prioritize the use of hardware security keys, Passkeys, or authenticator apps, avoid relying on SMS two-factor authentication, and enable security features such as withdrawal address whitelists and anti-phishing codes. At the same time, users should regularly check account login sessions and API key permissions, and be vigilant against scams impersonating customer service.

CZ also reminded users that if a platform suffers a data breach, they should promptly change passwords, revoke unnecessary API keys, check withdrawal records, and be alert to phishing attacks carried out using leaked information. In addition, leaked home addresses and asset holdings information may give rise to real-world extortion or robbery risks, and users should avoid publicly disclosing their personal asset situation.
