Presbyterian Healthcare Services

Presbyterian Healthcare Services, also known as PHS, is a healthcare organization based in the United States of America. It provides medical care to patients through its network of facilities and services. In addition to direct healthcare delivery, the organization offers health plan coverage to members. The organization serves individuals seeking both clinical treatment and insurance benefits. Its operations are centered on delivering health services and managing health plans for the communities it serves.

In August 2019, Presbyterian Healthcare Services experienced a data breach that exposed personal information of approximately 183,000 patients and health plan members. The organization notified those affected through mailed correspondence, though specific data types and attack vectors were not disclosed publicly. In July 2022, a phishing attack compromised an employee email account, leading to unauthorized access over several months. This incident exposed protected health information of 2,624 patients, including names, dates of birth, Social Security numbers, medical record numbers, health insurance details, and limited clinical billing information. No financial data was accessed in the 2022 breach, according to the organization's assessment. Presbyterian Healthcare Services detected the breach, notified affected individuals, and offered credit monitoring services to those with exposed Social Security numbers. Following the 2022 incident, the organization implemented enhanced email security measures and additional employee training to reduce future risks. These two incidents illustrate the cybersecurity challenges that Presbyterian Healthcare Services has faced in recent years.
