Hackers backed by the Russian government have breached the networks of multiple US defense contractors in a sustained campaign that has revealed sensitive information about US weapons-development communications infrastructure, the federal government said on Wednesday.
The campaign began no later than January 2020 and has continued through this month, according to a joint advisory by the FBI, National Security Agency, and the Cybersecurity and Infrastructure Security Agency. The hackers have been targeting and successfully hacking cleared defense contractors, or CDCs, which support contracts for the US Department of Defense and intelligence community.
