Coinbase Targeted in Major Data Breach Amid Bribery Scheme

On May 15, 2025, Coinbase, a leading cryptocurrency exchange, reported a serious data breach linked to bribery of customer support agents in India. Attackers exploited this insider access to gather sensitive customer information, leading to an attempted extortion demand of $20 million. In a bold move, Coinbase publicly refused to pay the ransom and instead offered a reward for information about the attackers. Fortunately, the breach did not compromise passwords, private keys, or Prime accounts. However, the estimated financial impact of the incident could range between $180 million and $400 million due to damages and mitigation efforts. This incident underscores the importance of robust internal security protocols and employee training to prevent insider threats in the rapidly evolving cryptocurrency landscape.
