Texas Attorney General investigates massive data breach affecting 4 million residents

Texas Attorney General Ken Paxton has launched an investigation into what he called “likely the largest breach in U.S. history,” following a data breach that compromised the sensitive information of approximately 4 million Texans.

The breach occurred over nearly three months, from October 21, 2024, through January 13, 2025, when an unauthorized third party gained access to Conduent’s system. The incident exposed protected health information of Texas residents, including vulnerable Texas Medicaid recipients.
