Some people enrolled in Medicaid in Wisconsin may have had their personal information stolen.

The state’s Department of Health Services on Friday said over 12 thousand people had their information exposed online. It wasn’t a hack. DHS said the information was posted online after a meeting in April of last year. That information included the first and last name, date of birth, gender, county location, Wisconsin Medicaid member ID number, and social security number of people enrolled in Medicaid in the state. DHS took down the personal information as soon as it was discovered. All 12 thousand people received a letter about the potential exposure, and will be given a free year of credit monitoring.
