Crypto Data Leaks Hit Coinbase Vendor and Bithumb: How Users Can Protect Their Accounts

Four reported data leaks involve Coinbase vendor Amplitude, Bithumb, Mirae Asset, and Daishin Securities. Exposed personal information can enable phishing, SIM swapping, impersonation, and social engineering. Unique passwords, passkeys, withdrawal restrictions, and careful handling of suspicious messages can reduce account risks. Crypto data leaks are back in the spotlight after four reported incidents involving cryptocurrency platforms and South Korean financial firms. According to an X post by CZ, Coinbase vendor Amplitude exposed some users’ contact information, while South Korean exchange Bithumb also experienced a user data leak. Two traditional securities firms, Mirae Asset and Daishin Securities, were also reportedly affected.
