Amplitude breach exposes contact data for some Coinbase customers, exchange says funds are safe - eGamers.io

Coinbase has clarified that while it hasn't experienced a direct data breach, a security incident at analytics vendor Amplitude has impacted contact information for a "small subset" of its users. The exchange emphasized that there's no evidence of unauthorized access to its own systems and that customer funds remain safe.

According to Coinbase's Support account, which posted about the incident on October 28, 2026, the breach affected various Amplitude customers, including some Coinbase users. The exchange is currently notifying affected individuals and regulators as required by law.

Limited disclosure details

Coinbase has not provided specific information about the number of affected customers, which types of contact data were exposed, or when the incident occurred. Users who want to know if they were affected will need to wait for direct notification from the exchange.

This incident follows a much more serious breach at Coinbase in May 2025, where cybercriminals compromised personal data of 69,461 customers by paying off overseas support agents. That attack exposed names, addresses, masked Social Security numbers, and government ID images.

Industry-wide vendor risks

Other crypto firms have also faced security issues through their partners. In September, hardware wallet maker Trezor revealed that a breach at shipping provider ShipMonk exposed the personal information of 67,000 U.S. customers, with some records dating back to 2019.

Even seemingly minor contact data breaches can pose significant risks, as stolen information remains valuable for years. Coinbase users who receive notifications should be vigilant about phishing attempts that use their personal details and never share account information with unsolicited contacts.
