Coinbase CEO Commends Indian Police for Arrest Post $400M Hack

Brian Armstrong, CEO of Coinbase, acknowledged the efforts of the Hyderabad Police in arresting an ex-agent linked to a $400M data breach. The breach, discovered in May 2025, involved compromising agents in India.

Brian Armstrong stated, “Thanks to the Hyderabad Police in India, an ex-Coinbase customer service agent was just arrested.” The fraudulent agent was a contractor based in India, influenced by attackers to reveal sensitive customer data.

Thanks to the Hyderabad Police in India, an ex-Coinbase customer service agent was just arrested. Another one down and more still to come. We have zero tolerance for bad behavior and will continue to work with law enforcement to bring bad actors to justice. – Brian Armstrong

The apprehension has emphasized Coinbase’s commitment to collaborating with law enforcement globally. This incident affected approximately 1% of their user base, involving sensitive customer data, excluding passwords and funds.

Coinbase is actively working with the US Department of Justice on criminal proceedings against those responsible. The breach did not directly steal crypto assets, but attackers utilized exposed data for social engineering tactics.

The financial implications range from remediation costs to potential reparations. Coinbase has estimated potential expenses between $180 to $400 million related to addressing the breach and its effects.

Philip Martin, Chief Security Officer, confirmed that involved agents were terminated. Paul Grewal, Chief Legal Officer, announced collaboration with multiple authorities. Coinbase maintains stringent standards, encouraging tips through a $20M bounty.
