Williams Brothers Construction Co., Inc., a Houston-based heavy-civil construction contractor specializing in roadway and bridge work, has reported a data breach to the Texas Attorney General.

The combination of Social Security numbers, driver’s license numbers, and health insurance information suggests this breach involved employee and employee-benefits-plan records rather than customer data. Separately, attorneys investigating the incident have reported that Williams Brothers Construction determined on August 3, 2026 that data containing personal information was subject to unauthorized access between January 10 and January 11, 2026, meaning the company may not have discovered the intrusion for nearly seven months.

According to the Texas Attorney General filing, the information involved included:
Williams Brothers Construction confirmed 21,537 affected Texas residents through its Texas Attorney General filing. The company has not disclosed whether individuals outside Texas were also affected.
Williams Brothers Construction has not publicly disclosed whether it is offering credit monitoring or identity protection services. Anyone who received a notice letter should review it directly for enrollment instructions or contact information specific to the offer made to them.
A Social Security number combined with a driver’s license number gives identity thieves nearly everything needed to open new credit or take out a loan in someone else’s name, and the exposed health insurance information adds the risk of medical identity theft or insurance fraud. If the roughly seven-month gap between the reported intrusion window and its discovery holds up, affected individuals may have gone unprotected for far longer than they should have. Affected individuals should monitor financial accounts, insurance statements, and credit reports closely.
Employers that collect Social Security numbers, driver’s license numbers, and health insurance information have a legal duty to secure that data and to notify affected individuals without unreasonable delay.
Your Personally Identifiable Information (PII) includes information that can be used to identify you, such as your name and other personal details. Organizations that manage healthcare data are legally required to safeguard this information. When PII is exposed in a data breach, it can potentially be used by cybercriminals to commit identity theft, financial fraud, or other misuse.
Much of the information involved in this incident may also qualify as Protected Health Information (PHI). PHI includes medical or healthcare-related data protected under federal and state privacy laws. When PHI is compromised, it can be misused for medical identity theft or insurance fraud.
