RNC Denies Data Breach, Says Russian Hackers Only Reached Contractor's Systems On 7/6/21 at 7:33 PM EDT The Republican National Committee (RNC) has denied a report claiming that their computer systems were hit by a successful ransomware attack from the Russian hacker group Cozy Bear last week, saying that an attack did happen but affected one of its contractors only. A Bloomberg report published Tuesday, based on anonymous sources that the outlet said were familiar with the matter, claimed that RNC computer systems had been comprised in the attack through the California-based firm Synnex. However, RNC Chief of Staff Richard Walters quickly disputed the report, insisting that no RNC data had been compromised.
