Russian hackers have infiltrated US defense contractors, CISA and FBI warn

State-sponsored threat actors originating from Russia have been somewhat successful in stealing sensitive data from the US Department of Defence (DoD), American security agencies have said.

In an advisory signed by the Federal Bureau of Investigation (FBI), National Security Agency (NSA), and Cybersecurity and Infrastructure Security Agency (CISA), it was revealed Russians targeted the DoD through the supply chain – by trying to breach endpoints from cleared defense contractors (CDC) and subcontractors.
