Russian government hackers breached the computer systems of the Republican National Committee last week, around the time a Russia-linked criminal group unleashed a massive ransomware attack, Bloomberg News reported Tuesday, citing two people familiar with the matter. From the report: The government hackers were part of a group known as APT 29 or Cozy Bear, according to the people. That group has been tied to Russia’s foreign intelligence service and has previously been accused of breaching the Democratic National Committee in 2016, and of carrying out a supply-chain cyberattack involving SolarWinds Corp., which infiltrated nine U.S. government agencies and was disclosed in December. It’s not known what data the hackers viewed or stole, if anything. An RNC spokesman on Tuesday denied its systems were breached and referred to an earlier statement.

“Microsoft informed us that one of our vendors, Synnex, systems may have been exposed,” Mike Reed, a spokesman for the RNC, said on Saturday. “There is no indication the RNC was hacked or any RNC information was stolen. We are investigating the matter and have informed DHS and the FBI.” The attack on the RNC, coupled with the recent ransomware attack, is a major provocation to President Joe Biden, who warned Russian President Vladimir Putin about cyberattacks at a June 16 summit. It’s not clear if the attack on the RNC is connected in any way to the ransomware attacks, which exploited multiple previously unknown vulnerabilities in software from Miami-based Kaseya Ltd.
