Keystone Health is just your friendly neighborhood doctor’s office. It is a Pennsylvania-based healthcare system with over 540 employees.
The breach was an attack on the company’s internal systems. The infringement was thoroughly investigated immediately after its discovery, as Keystone wanted to find the full extent of the breach. After the investigation ceased, the company posted a notification on its website and sent notices to the affected customers.
The breach occurred via a cyberattack that temporarily glitched specific company systems. As soon as Keystone discovered the glitch, the company immediately contacted the authorities and commissioned a third-party security firm to look into the glitch.
This breach occurred on August 19, 2022.
The breach impacts hundreds of thousands of Keystone Health patients. Keystone has locations across the US, some of which are group homes and the like. People living in group homes are more likely to be victimized; depending on the group home, the residents may be elderly, disabled, or even minors.
The breach affected over 235,000 patient files. The leaked data includes clinical information, names, and social security numbers. Having things as simple as a name can make finding the victims easier. With someone’s name and the internet these days, you can find out almost anything about anyone. “If you believe you may be affected but do not receive a letter by November 14, 2022, please contact our toll-free dedicated external call center at (855) 532-1263, Monday through Friday, 9:00 a.m. to 6:30 p.m., Eastern Standard Time, excluding major U.S. holidays,” the notice stated.
