Amplitude, a third-party analytics vendor used by Coinbase, suffered a security incident that exposed contact information linked to more than 70,000 users across affected clients. Coinbase said its own systems were not breached and found no evidence of unauthorized internal access.
Why it matters
Coinbase said the exposure was limited to contact details for a small subset of its users. The incident highlights the privacy and compliance risks created when analytics vendors handle customer-related data outside a platform's core systems.
Market impact
Coinbase said passwords and customer funds were not affected, and that it is notifying affected users and relevant regulators as required. The event is therefore primarily a third-party privacy and compliance issue, rather than a reported loss of customer assets.
