Coinbase Says Its Systems Were Not Breached—but Exposed Contact Data Still Gives Scammers an Opening

Coinbase says its own systems were not breached after a security incident at analytics provider Amplitude exposed contact information belonging to a small subset of customers. That distinction matters.

It does not, however, make the exposed data harmless.

According to CryptoSlate, Coinbase found no evidence that anyone gained unauthorized access to its systems, and customer funds remained secure. The exchange said it was notifying affected customers and regulators, but it had not disclosed how many people were affected or precisely which contact fields were exposed.

Coinbase has not had a data breach.

Amplitude, an analytics vendor, experienced a security incident which impacted a small subset of Coinbase customer contact data, among other Amplitude customers.
