U.S. Department of Homeland Security
DHS had a privacy incident that resulted in the exposure of information for 247,167 active and retired federal employees.
The database utilised by the DHS Office of the Inspector General (OIG) and kept in the Department of Homeland Security OIG Case Management System was compromised by a data breach.
Employee names, Social Security numbers, dates of birth, jobs, grades, and duty locations are among the data that has been made public.
In addition to putting additional security measures in place to restrict access to this kind of information, the Department of Homeland Security notified those who were impacted through notification letters.
