Nasdaq-listed cryptocurrency exchange Coinbase has denied reports of a hack, saying customer funds are safe.

The exchange clarified that the incident that led to the breach of customer data originated at Amplitude, a third-party analytics provider, and not the exchange itself. The exposed data includes only a “small subset” of contact information, alongside data related to other Amplitude clients, Coinbase Support’s X handle said.

It said the exchange is informing impacted customers by email as required by law, while stressing that its systems have not detected any unauthorized access.

The disclosure underscores supply-chain risks, meaning customers can face security risks via third parties even when a company’s core infrastructure remains secure. Coinbase did not specify how many customers were affected or exactly which contact-data fields were involved, leaving key details unresolved.

While customer funds remain safe, exposed email addresses and phone numbers can still serve as valuable raw material for phishing and social-engineering attacks, even if passwords, private keys, and funds were not compromised.

The incident comes as several financial firms in South Korea also disclosed customer-data breaches. Daishin Securities said personal information belonging to 38,490 customers was hacked, including names, email addresses and mobile phone numbers, after the brokerage detected signs of unauthorized access by hackers last week.

Meanwhile, some personal information of Bithumb customers was leaked in a cyberattack by an external party, according to Yonhap News Agency. Financial authorities have also begun an inspection into the data breach at Mirae Asset Global Investments.
