U.S. authorities are investigating the online leak of home addresses of senior officials and former officials from the FBI, the Department of Homeland Security and other agencies, CBS News reported on Wednesday.
Investigators believe a right-wing group was behind posting the information, CBS reported, citing unidentified sources.
The Department of Homeland Security confirmed the leak but would not elaborate on who was affected or how many addresses had been leaked.
“DHS has notified employees who were identified in the posting and encouraged them to be vigilant. DHS will adjust security measures, as appropriate, to protect our employees,” said Homeland Security spokeswoman Marsha Catron.
