On May 3, 2024, Thompson & Horton, LLP (“T&H”) detected unusual activity on its network and immediately launched an investigation with third-party forensic specialists. The breach occurred when an unauthorized individual accessed information stored on a T&H server managed by its IT service provider, MSP. Although T&H reports no evidence of misuse, the exposure of sensitive data constitutes a serious privacy risk.

Founded in 2009, Thompson & Horton is a law firm that provides legal services to educational institutions, local governments, and private businesses in the state of Texas. Following the incident, T&H notified federal law enforcement and offered affected individuals complimentary credit monitoring and identity protection services.

Your Personally Identifiable Information (PII) includes details that can be used to identify you. Organizations are legally obligated to safeguard this data, and failure to do so can result in statutory fines and other legal consequences. If PII is stolen, it may be exploited by criminals to commit identity fraud.

A specific category of PII is Protected Health Information (PHI), which pertains to personal medical data. PHI is safeguarded under both federal and state regulations. Entities such as healthcare providers and businesses that manage PHI must ensure its security. Just like PII, compromised PHI can be misused by identity thieves, and it’s common for cybercriminals to use both types of information together.

If your data has been exposed in a breach, one of the most effective steps you can take is to enroll in credit and identity monitoring services promptly.

Residents of California benefit from additional privacy protections under the California Consumer Privacy Act (CCPA), which grants enhanced rights regarding personal data. Additionally, California residents also benefit from medical privacy protections under the Confidentiality of Medical Information Act (CMIA), which specifically grants enhanced protections for confidential medical data.

If you received a NOTICE OF DATA BREACH letter from Thompson & Horton, your personal, financial, and/or medical information may be at risk. This type of data can be exploited by identity thieves to commit fraud and other crimes.
