One of the biggest crypto hacks this year has led to an arrest in India, after a former Coinbase support agent allegedly aided hackers in a massive $400 million data breach. Indian police arrested a former Coinbase customer service agent linked to a major data breach involving insider bribery. Hackers demanded a $20 million ransom after accessing sensitive customer data, though Coinbase refused to pay. The breach affected about 1 percent of Coinbase’s customer base, highlighting the threat of insider attacks.
The breach resulted in a $20 million ransom demand and is expected to cost Coinbase up to $400 million in remediation. The former agent has now been arrested by Hyderabad Police in coordination with Coinbase and international law enforcement agencies, marking a key step forward in the investigation. We have zero tolerance for bad behavior and will continue to work with law enforcement to bring bad actors to justice. Thanks to the Hyderabad Police in India, an ex-Coinbase customer service agent was just arrested.
Another one down and more still to come. Arrest marks a breakthrough in global crypto crime investigation. This insider access was exploited by hackers in May 2025 to steal data, including names, addresses, and email information of customers. While no passwords or crypto assets were directly taken, the stolen data was used for phishing attacks and social engineering schemes.
