•[ data leak, healthcare ]
TriZetto Provider Solutions, a Cognizant-owned vendor providing revenue management services to healthcare organizations, reported a cybersecurity incident affecting a customer web portal. TriZetto identified suspicious portal activity on 10/02/2025, secured the portal, and engaged Mandiant to investigate and validate remediation. Forensic work determined an unauthorized third party had been accessing historical eligibility transaction reports within TriZetto systems since November 2024, nearly a year before detection. The reports contained protected health information for patients of certain healthcare provider clients. TriZettos review determined compromised data could include patient and primary insured names combined with other personal and insurance information such as addresses, dates of birth, Social Security numbers, member/Medicare numbers, insurer names, and related demographic health and coverage details. TriZetto stated it believed the actor had been eradicated and no further unauthorized portal activity was detected after 10/02/2025; the total number of affected clients/individuals was not yet publicly confirmed.

•[ malware, ransomware, phishing ]
The Record described a newly identified Android malware/ransomware campaign (DroidLock) distributed through phishing websites that trick users into installing fake apps and then lock devices behind a ransom message. The reporting focuses on a broad campaign targeting Spanish-speaking users rather than a single named victim organization with a discrete primary effect suitable for this datasets event unit.
