Worldwide cyberattack includes potential health information of some Missouri Medicaid participants

The Missouri Department of Social Services says May’s worldwide cyberattack involved MOVEit Transfer, a third-party software application. 

The information involved in this hack may include the name of individual Missouri Medicaid participants, their department client number, date of birth, possible benefit eligibility status or coverage, and medical claims information. 

While the investigation is ongoing, the Department of Social Services is sending letters to Medicaid participants who are potentially impacted by this crime. 

The state agency is still reviewing the matter, because it says files are large, are not in plain English, and are not easily readable because of how they are formatted.  

The department encourages Medicaid participants to freeze their credit for free and monitor their credit.
