2024 Leidos — internal investigation documents leaked; tied to prior Diligent/Steele vendor incident

In July 2024, mainstream and trade press reported that internal Leidos documents—described as stemming from material housed in Diligent Corp.-family investigation tooling (linked in coverage to a 2022 incident involving Steele Compliance Solutions)—had surfaced on criminal forums. Leidos public statements relayed by journalists emphasized no compromise of its corporate network and no sensitive customer data in the same sense as core federal contract systems, while acknowledging the third-party lineage of the leaked cache. The episode is indexed here as a vendor-hosted governance/investigations data exposure with national-security-adjacent reputational risk.
