The OAG dataset does not consistently identify the attack method, so these are the largest published breach reports by affected Texans, not necessarily the largest confirmed hacks by technique.

Most Common Data Exposures

Among 2026 reports, the most frequently listed exposed data types include:

• Name of individual
• Social Security number information
• Medical information
• Address
• Driver’s license number
• Financial information

Social Security numbers appeared in 357 of the 426 year-to-date reports, while medical information appeared in 244 reports.

Why This Matters for Texas Law Firms

Law firms hold sensitive client records, financial data, identification documents, medical information, employment records, and privileged communications. The breach trends reported to the Texas OAG show why firms should treat cybersecurity as both an operational and compliance priority.

For law firms, the practical lessons are clear:

• Maintain documented access controls
• Require multi-factor authentication
• Review vendor access and contracts
• Test backup restoration
• Train staff on phishing, smishing, and social engineering
• Keep incident response contacts and procedures current

Immediate Steps to Reduce Risk

Texas law firms should review whether they can document:

• Who has access to sensitive systems
• Which vendors can access client or firm data
• Whether MFA is enabled on email, financial, and document systems
• Whether backups are protected from ransomware
• Whether staff know how to report suspicious messages
