Multiple healthcare-related breach disclosures expanded significantly, led by TriZetto Provider Solutions reporting to regulators that 3,433,965 people were affected after an attacker used a web portal to access historical eligibility reports containing sensitive data (including SSNs and insurance information). Separately, Conduent Business Services told Wisconsin regulators that its incident now impacts “25 million-plus” people nationwide; the Xerox spinoff had previously reported ~15.5 million affected in Texas, prompting an investigation by Texas AG Ken Paxton, while reporting noted the event is still smaller than the largest U.S. health-data breach on record.
Reporting on the Change Healthcare ransomware incident reiterated that UnitedHealth estimated roughly 190 million people were affected, with congressional testimony attributing initial access to a Citrix remote access portal lacking MFA, followed by data theft and ransomware deployment; reporting also cited a $22 million ransom payment. In the Asia-Pacific region, a separate healthcare privacy incident involving New Zealand’s ManageMyHealth patient portal was cited as exposing data from ~120,000 people, and was used to underscore governance, access control, and third-party oversight gaps as recurring drivers of healthcare-sector exposure.

10 events from the most recent confirmed update back to the earliest known activity.
TriZetto updated its report to Oregon's Department of Justice to state that 3,433,965 people were affected and filed breach notifications in multiple states. Some private medical providers and several states also publicly confirmed victim counts.
In a filing to Wisconsin regulators, Conduent said the breach affects at least 25 million people nationwide, a major increase from earlier state-level disclosures. Texas and Montana officials were also investigating impacts tied to Blue Cross Blue Shield members.
County governments in Oregon previously warned that the TriZetto incident affected hundreds of thousands of residents whose data was exposed through the compromised portal.
A breach of New Zealand's ManageMyHealth patient portal exposed sensitive information for roughly 120,000 people, making it one of the country's most significant healthcare privacy incidents.
TriZetto began notifying customers in December after investigating the incident with law enforcement and Mandiant.
TriZetto discovered the breach in October 2024, according to later reporting cited in the update on the incident.
Conduent first publicly disclosed the hacking incident in an SEC filing in April 2025, before later state notifications expanded the known scale of impact.
Conduent said it discovered the breach on 2025-01-13 and later determined the compromise had been ongoing since October 2024.
At TriZetto Provider Solutions, malicious activity began in November 2024 when an attacker accessed historical eligibility reports through a web portal, exposing data later described as including Social Security numbers, addresses, and health insurance numbers.
Conduent said attackers had unauthorized access to its servers from 2024-10-21 through 2025-01-13, potentially exposing sensitive personal and health-related data affecting patients nationwide.
