Connecticut says data from 41,000 Medicaid members exposed in portal breach; the second portal incident this year

Multiple security incidents from 2020–2026 involving Gainwell Technologies, Hartford HealthCare, and subcontractors resulted in unauthorized access to provider portals, credential compromise, and a mailing error that exposed protected health information (names, Social Security numbers, member IDs, diagnoses, billing and payment details). Affected counts reported include 3,317; 810; 1,955; 912; 22,500; and a June 2026 incident impacting approximately 41,000 HUSKY members, demonstrating repeated breaches of Medicaid-related systems and significant PHI exposure.
