Fortune 500 integrated services firm R.R.Donnelley & Sons (RRD) is the latest victim of the hacking collective known as the Conti Group. According to regulatory disclosures RRD was the victim of a network breach that resulted in stolen data in December.
RRD, a global firm with 33,000 employees, disclosed incident details in its U.S. Securities and Exchange Commission (SEC) 8-K form – filed Dec. 27. The company said it “had recently identified a systems intrusion in its technical environment,” according to the filing.
“The Company promptly implemented a series of containment measures to address this situation, including activating its incident response protocols, shutting down its servers and systems and commencing a forensic investigation,” the company disclosed. It also isolated a portion of its technical environment to try to contain the intrusion, the company said.
RRD didn’t name the perpetrator of the attack in the filing. However, a published report in BleepingComputing claims it was Conti, citing an online post the cybercriminal group made claiming responsibility and leaking 2.5GB of data allegedly stolen from the company on Jan.
