Full breach record for MemberSource Credit Union →MemberSource Credit Union (Houston, TX) submitted a sample notice of data event to the California Attorney General under SB24, with a breach date of June 3, 2025. The available redacted notice contains only the generic 'Steps You Can Take to Help Protect Your Information' boilerplate (credit-bureau contacts, fraud alert / security freeze instructions, and state-specific AG contact addresses). The substantive sections describing what happened, when it was discovered, the cause/attack vector, the categories of personal information affected, and the number of individuals impacted are not present in the extracted pages. The Rhode Island residents-impacted figure is left as a placeholder ('[#]'). No threat actor, attack category, or data-type enumeration can be reliably extracted from the available source.
