QRS Inc, a Tennessee-based healthcare technology services company and provider of the Paradigm practice management and electronic health records (EHR) solution, has announced a data breach involving the protected health information (PHI) of almost 320,000 individuals. The cyberattack was detected on August 26, 2021, three days after a server was breached.
QRS explained in its breach notification letters that a hacker gained access to the electronic patient portal and potentially accessed and exfiltrated the PHI of patients of some of its healthcare provider clients.
When the breach was detected, the compromised server was immediately taken offline to prevent further unauthorized access and an investigation was launched to determine the nature and scope of the attack.
Assisted by a third-party computer forensics firm, QRS determined the breach was limited to a single server. No other QRS systems nor those of its clients were affected. The compromised server contained files that included PHI such as names, addresses, dates of birth, Social Security numbers, patient identification numbers, portal usernames, and medical treatment and diagnosis information.
QRS said unauthorized access and data exfiltration could not be ruled out, but it is not aware of any cases of actual or attempted misuse of patient data.
On October 22, 2021, QRS started sending notification letters to all affected individuals on behalf of its affected healthcare provider clients. Individuals who had their Social Security number exposed have been offered complimentary access to identity theft protection services as a precaution. QRS said it is taking steps to assess and address the risk of a similar incident occurring in the future.
Law enforcement has been notified and the breach has been reported to the Department of Health and Human Services’ Office for Civil Rights (OCR). The OCR breach portal indicates the PHI of up to 319,778 individuals was stored on the compromised server.
