On June 1, 2026, Quantum Health detected a service outage, which affected the availability of certain internal and external systems. Upon identifying the outage, they  secured and isolated their systems, while simultaneously launching an investigation with the support of third-party forensics experts. They also reported the incident to federal law enforcement.

Their investigation determined that the service outage was related to unauthorized access to their IT network, resulting from a user responding to a vishing call on May 29, 2026. Between May 29, 2026 and June 1, 2026, the unauthorized party accessed and acquired files from certain Quantum Health systems.

Because of this breach, Quantum will be offering all individuals on the State Employee medical plan 2 years of credit monitoring through a company called Kroll. All employees will be receiving a letter from Kroll/Quantum regarding the breach with instructions on how to sign up for the credit monitoring. However, individuals MUST OPT-IN to the credit monitoring services (it will not cost anything and it will not auto-renew after the 2 year period expires). This protection will not be automatic, every individual needs to take the steps to opt-in.
