The company, more commonly known as HCIactive, previously filed lowball estimate breach reports to several state attorneys general. But in a Jan. 7 breach report submitted to Oregon state regulators, HCIactive said the incident affected a total of about 3.06 million individuals.
Based on HCIactive’s latest breach tally provided to Oregon regulators, the company’s hacking incident as of Wednesday would rank among the 10 largest of the 691 protected health information breaches reported in 2025.
In its breach notification statement, HCIactive said on July 22, 2025, the company became aware of suspicious activity related to its IT network.
The company worked to “quickly” secure all it systems and investigate the incident, determining that an “unauthorized actor” acquired files from HCIactive’s network over several days, between July 8, 2025, and July 12, 2025.
Potentially compromised information varied by individual but included medical data, including doctors, diagnoses, prescriptions, lab results, images, care and treatment information. Hackers also potentially stole names, addresses, dates of birth, Social Security numbers, phone numbers, email addresses and health insurance enrollment data such as health plans and insurance companies. Also affected were claims data such as explanation of benefits, billing codes and account numbers.
HCIactive did not immediately respond to Information Security Media Group’s request for additional details pertaining to the hacking incident.
That included a request for comment on whether an “AI-driven security, compliance and platform modernization” initiative the company announced in December was in response to the July hack.
The company said that as part of its “longstanding commitment to AI First and AI Everywhere,” it is accelerating the deployment of advanced security controls that leverage AI, automated monitoring, microservice segmentation and next-generation encryption.
