​​​​​​​​On May 8, 2025, Chambers County Public Hospital District No. 1 (“Chambers Health”)reported a significant cybersecurity incident to the Texas Attorney General’s Office. The incident, which began with a network disruption on July 19, 2024, was later confirmed to involve unauthorized access to sensitive personal and health information (the “Data Breach”). Approximately 84,082 individuals have been impacted. 

The investigation revealed that an unauthorized third party accessed and acquired personal data. Notably, on December 5, 2024, a threat actor known as “mapateam” claimed responsibility for the Data Breach, alleging the theft of 1.52TB of documents, including private and financial information, which were posted on the open web.

Recently, Chambers Health began sending data breach notification letters to individuals affected by the Data Breach. Each letter offers one year of complimentary credit monitoring and identity theft protection services. As of now, Chambers Health has not disclosed any further information about the Data Breach. If you received a data breach notification letter from Chambers Health, it indicates that your information was affected by the Data Breach.

Established over 70 years ago, Chambers County Public Hospital is a public hospital organization serving Chambers County, Texas. The district provides essential healthcare services to residents in Anahuac and the surrounding communities and is governed by a five-member Board of Directors elected by local taxpayers.

WHAT INFORMATION IS INVOLVED IN THE CHAMBERS COUNTY PUBLIC HOSPITAL DISTRICT NO. 1 DATA BREACH?

  • Full names,
  • Social Security numbers,
  • Dates of birth,
  • Addresses, 
  • Driver’s license numbers,
  • Medical information
  • Health insurance information. 

This information is called your Personally Identifiable Information (“PII”). It tells others about you and is considered part of your identity. Businesses are required to secure this information or risk facing statutory penalties, among other legal penalties. Stolen PII can be used by identity thieves to engage in fraudulent activity using your identity. 

Personal medical information (a specific type of PII) is referred to as Protected Health Information (“PHI”). It is protected under both state and federal law. Healthcare providers and other businesses who handle PHI are required to protect that information. Like stolen PII, stolen PHI can be used by identity thieves to engage in fraudulent activity using your identity. Quite often, PII and PHI are used in conjunction by hackers.

The best way to protect yourself after a data breach is to sign up for credit and identity protection services as soon as possible.
