(Reuters) -Hackers have leaked internal documents stolen from Leidos Holdings, one of the largest IT services providers to governments, Bloomberg News reported, citing a person familiar with the matter.
The company recently became aware of the issue and believes the documents were taken during a previously reported breach of a Diligent system it used, the report said, adding that Leidos is investigating it.
The Virginia-based company, which counts the US Department of Defense as its primary customer, used the Diligent system to host information gathered in internal investigations, the report added, citing a filing from June 2023.
Leidos said it has confirmed that the issue stems from a previous incident affecting a third-party vendor for which all necessary notifications were made in 2023.
"This incident did not affect our network or any sensitive customer data," the company said.
A spokesperson for Diligent said the issue seems to be related to an incident from 2022, affecting its subsidiary Steele Compliance Solutions.
The company notified impacted customers and had taken corrective action to contain the incident in November 2022.
