A glitch in the US Department of Health and Human Services computer system compromised the personal information of public assistance applicants, including Social Security and bank account numbers.
Information from 31 applications submitted online was sent out between December and June to 39 random addresses in the department’s system.
The personal information of 79 people was exposed, as some applications included multiple members of a household.
