The data includes names, birth dates, Social Security numbers (SSN), health insurance member numbers, provider names, health insurance names, primary insured information, and other demographic, health, and health insurance information. TriZetto stressed that payment card, bank account, and other financial information, was not affected by this incident. “At this time, we are not aware of any identity theft or fraud related to the use of any affected individual’s information,” it added, although data such as this one can surface on the dark web even years later. In the Maine AG filing, the company said exactly 3,433,965 people were affected. To help them, TriZetto is offering free identity theft monitoring services through Kroll.
