In June 2025, Nasdaq-listed cryptocurrency exchange Coinbase faced a significant data breach. This incident was not due to a system hack but rather a result of user data leakage by an Indian employee of an outsourced service provider, who had received payment from hackers. Approximately 97,000 users were affected by this breach. Coinbase refused to pay the ransom demanded by the hackers and instead offered an equivalent sum as a reward for information leading to their capture. The estimated losses from this incident range from $180 million to $400 million, primarily allocated for customer compensation, system restoration, and enhanced security measures. Coinbase has terminated the employees involved and is planning to fortify its internal security management protocols. To further mitigate risks, the company is now requiring all job interviews to be conducted on-site and supplemented with fingerprint identification.
