Coinbase said at least 69,461 customers had personal and financial information stolen during a months-long data breach that it disclosed last week. The crypto giant confirmed the number of affected customers in a filing with Maine’s attorney general on Wednesday, as required by the state’s data breach notification law.

A mandatory filing to the Maine Attorney General says 69,461 customers nationwide were affected and dates the breach back to last December.

Coinbase disclosed that 69,461 of the crypto exchange’s users were affected by a recently unveiled data breach, which took place last year.
