The dental insurer Managed Care of North America (MCNA)—one of the largest dental health insurers in the United States—says the personal information of nearly 9 million individuals has been compromised after its computer system was hacked.
The Atlanta-based company—which bills itself as the leading dental benefits manager of government-backed plans for children and seniors—said in a May 26 notice that it had become aware that a “criminal accessed our computer system without our permission” in March.
