Greater Dallas Healthcare Enterprises

Greater Dallas Healthcare Enterprises (GDHE), a subsidiary of Tenet Healthcare Corporation, experienced a data breach where an unauthorized third party gained access to an employee’s email account. The breach occurred between July 28, 2023, and August 15, 2023. The compromised email account contained sensitive information, including names, dates of birth, addresses, medical and treatment information, billing information, and claims information. There was evidence that the hackers removed some of this data[1][3].

GDHE learned of the breach on August 11, 2023, and took immediate steps to contain the incident and investigate the extent of the data compromise. Following the investigation, GDHE began sending out data breach notification letters to all affected individuals on October 2, 2023. These letters aimed to inform victims about the breach and the specific information that was compromised[1][3].

The breach affected as many as 143,833 individuals, and GDHE has been working to enhance security and monitoring capabilities to prevent future incidents. The compromised Office365 account was separate from GDHE’s internal network and systems, which were not affected by the incident[1][3].

GDHE is a healthcare provider based in Dallas, Texas, and is part of Tenet Healthcare Corporation, a national diversified healthcare services company also headquartered in Dallas. Tenet Healthcare employs more than 78,000 people and generates approximately $19 billion in annual revenue[1].

Victims of the data breach have been advised to monitor their account statements and credit reports for any unauthorized activity and to be vigilant against potential fraud or identity theft. Legal options may also be available to those affected, and they are encouraged to seek advice from data breach lawyers[1][3].
