Coinbase CEO Brian Armstrong announced the arrest of a former customer service agent in India, linked to a May data breach where hackers bribed employees outside the U.S. to steal sensitive customer information. The breach, which involved a $20 million ransom demand and an impersonation scheme targeting customers, could cost Coinbase up to $400 million. Armstrong thanked Hyderabad Police for the arrest, reiterating the company's zero-tolerance policy for misconduct and commitment to working with law enforcement.
