A hacker group associated with the Russian government breached the computer systems of the Republican National Committee last week in a massive ransomware attack, Bloomberg first reported.
The attack follows a separate Russia-based criminal group unleashing an attack that compromised the computer systems of at least 1,000 businesses. No connection has been established between the attacks.
It is unclear what, if any, information the Cozy Bear hackers found. Danielle Alvarez, the GOP communications director, released a statement saying that while it was informed by Microsoft that their systems may had been exposed, “no RNC data was accessed.”
Alvarez added that it “will continued to work with Microsoft, as well as federal law enforcement officials on this matter.”
An RNC spokesperson told Bloomberg it is investigating the situation and has already informed the FBI and the Department of Homeland Security.
“Over the weekend, we were informed that Synnex, a third party provider, had been breached,” RNC chief of staff Richard Walters said in a statement. “We immediately blocked all access from Synnex accounts to our cloud environment.”
