U.S. healthcare technology giant Change Healthcare has confirmed a cyberattack on its systems. In a brief statement Wednesday, the company said it was “experiencing a network interruption related to a cyber security issue.”
“Once we became aware of the outside threat, in the interest of protecting our partners and patients, we took immediate action to disconnect our systems to prevent further impact,” Change Healthcare wrote on its status page. “The disruption is expected to last at least through the day.”
The incident began early on Wednesday morning on the U.S. East Coast, according to the incident tracker.
The specific nature of the cybersecurity incident was not disclosed. Most of the login pages for Change Healthcare were inaccessible or offline when TechCrunch checked at the time of writing.
Michigan local newspaper the Huron Daily Tribune is reporting that local pharmacies are experiencing outages due to the Change Healthcare cyberattack.

In 2022, health insurance giant UnitedHealth Group completed its merger of U.S. healthcare services giant Optum and Change Healthcare in a $7.8 billion deal, which allowed Optum broad access to patient records on tens of millions of Americans.
Optum provides technology and data to insurance companies and healthcare services. Both Optum and Change Healthcare are owned by health insurance giant UnitedHealth Group.
When reached by email Thursday, Optum spokesperson Andrew Krejci declined to comment beyond what was published on the incident tracker. Krejci would not say for what evidence Optum has to suspect a cybersecurity incident.
Neither spokespeople for Change Healthcare or UnitedHealth Group have commented.
Late Thursday, UnitedHealth attributed the cyberattack to likely government-backed hackers, without saying which nation state.
Updated with response from Optum, and corrected the start of the cyberattack to early Wednesday.
