Newkirk Products Inc. Friday announced a cyber security incident involving unauthorized access to a server containing certain personal information for 3.3 million members of about a dozen health insurance plans for which it issues health care ID cards. The data potentially subject to unauthorized access varies by plan but includes some combination of: the member's name, mailing address, type of plan, member and group ID number, names of dependents enrolled in the plan, primary care provider, and in some cases, date of birth, premium invoice information and Medicaid ID number. No health plan systems were accessed or affected, the company said. The company is mailing letters to affected individuals and offering them two years of free identity protection and restoration services.
