Coinbase Faces Major Security Crisis as KYC Data Breach Exposes 70,000 Users

In a alarming development for cryptocurrency security, Coinbase has suffered a significant data breach compromising the personal information of 70,000 customers. The incident, which occurred in December 2024, involved a TaskUs customer service agent in India who was bribed to leak sensitive Know-Your-Customer (KYC) data. The breach included photographs of government-issued IDs, home addresses, and other private details, potentially exposing affected users to identity theft and financial fraud. Security experts estimate this breach could cost Coinbase up to $400 million in damages and reputational harm. This event raises serious questions about third-party vendor security protocols in the cryptocurrency industry, particularly for major exchanges handling sensitive user data. The breach comes at a time when regulatory scrutiny of crypto exchanges is intensifying globally, potentially impacting Coinbase’s compliance standing. As of June 2025, the full extent of the damage remains under investigation, with Coinbase expected to implement enhanced security measures to prevent future incidents of this nature.

Coinbase KYC Data Breach Exposes 70,000 Users, Raises Security Concerns

A significant data breach at Coinbase has compromised the personal information of 70,000 customers, potentially costing the company up to $400 million. The incident originated in India, where a TaskUs customer service agent was bribed to leak sensitive data. The breach, which occurred in December 2024, involved the employee photographing government-issued IDs, home addresses, and other private details using a personal device.

Coinbase disclosed the breach in an SEC filing in May 2025, confirming unauthorized access to both customer and employee data. The incident has sparked debate over the efficacy of Know Your Customer (KYC) protocols, which were designed to combat money laundering but may inadvertently expose legitimate users to risks. Emerging threats like AI-generated fake IDs further complicate the security landscape.
