An Analytics Vendor Slip, Not a Coinbase Hack, Left Some Customer Contact Details Out in the Open

Coinbase told users on Wednesday that the problem started at Amplitude, a company that supplies it with analytics tools, and did not begin on its own servers. Only a small group of customers was touched, alongside people who use other Amplitude clients. The exchange says it has found no sign that anyone broke into its systems and that customer funds were never involved.

What Users Should Watch For

Even when money stays put, names tied to emails and phone numbers are handy for scammers. Anyone who hears from Coinbase about this should treat unexpected messages, links or calls with caution and never share verification codes or login details with a caller.
