“Officials with the Arkansas Department of Human Services said they have discovered a data breach that released client data.

The officials said the breach came on Sept. 16 when an employee sent emails from her DHS email account to her personal Yahoo email account. The emails had attachments of spreadsheets that listed 925 DHS Medicaid clients who had been diagnosed with the flu.

Listed in the attachments were the person’s Medicaid ID, date of birth, gender, county, zip code and diagnosis. Officials noted that names, Social Security numbers full addresses and financial information were not disclosed in the breach.

Department officials added that they had notified the affected clients by mail about the breach.”
