Hackers have leaked internal documents stolen from Leidos Holdings, a major IT services provider to the US government. The leaked documents, reportedly obtained from a 2022 breach of Diligent Corp.’s Steele Compliance Solutions subsidiary, contain information gathered from internal investigations. While Leidos is investigating the incident, the leak raises concerns about the security of sensitive information shared with the company by its numerous government and commercial clients, including the US Defense Department, Department of Homeland Security, and NASA.
