The article I read about was the US Marshals Service. They had inmates information exposed. More than 387,000 former and current inmates had their information exposed. Information stolen was names, dates of birth, social security numbers, and home addresses.  They are doing numerous fixes to ensure this breach doesn't happen in the future. The hackers were not caught.
