State health department security breach affects data of 10,400 Missourians

The Missouri Department of Health and Senior Services sent out more than 10,400 letters to individuals alerting them of the recent discovery of a security breach involving their personal information, the department announced Friday in a press release.

The breach arose sometime before Sept. 30, 2016, as a result of a department information technology contractor improperly retaining DHSS information and storing it in a file that was not protected by a password, according to the release.

Information found in the files includes names, dates of birth, identification numbers issued by state agencies and “a very limited number” of social security numbers, according to the department.

The department said it has no reason to believe the information was “viewed or used by anyone intending harm.”

The State of Missouri learned about the breach on Aug. 30 of this year, according to the release, and has been working since then to determine the scope of the breach.
