In the October 2023 ransomware incident, Dallas County experienced a significant security breach, with over 200,000 individuals' personal information compromised. Among the data exposed were names, Social Security numbers, dates of birth, driver's license or state ID numbers, and for some, medical and health insurance information. Despite refusing to pay the ransom, the Play ransomware group published the stolen documents, prompting Dallas County to enhance its cybersecurity measures, including deploying EDR tools, initiating password changes, and blocking malicious IP addresses. They also offered credit monitoring and identity theft protection to affected individuals.
