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.

The large-scale extortion scheme targeting Coinbase customers has affected close to 70,000 individuals, according to a new official document from the US-based cryptocurrency exchange. Following its disclosure of the breach on May 15, Coinbase filed a data breach notification to the Office of Maine's Attorney General on May 21.

A data breach affecting nearly 70,000 Coinbase users led to firings, heightened security, and a $20 million bounty.
