Coinbase Denies Hack as Third-Party Data Breach Exposes Customer Information

Nasdaq-listed cryptocurrency exchange Coinbase has denied reports of a hack targeting its platform, stating that customer funds remain safe and that its own systems have shown no signs of unauthorized access.

The company said the incident originated at Amplitude, a third-party analytics provider, rather than Coinbase's infrastructure. According to a statement shared by Coinbase Support on X, the exposed information covers a small subset of contact details belonging to Coinbase customers, along with data associated with other Amplitude clients.
