A Department of Homeland Security report says Russian intelligence services performed spearphishing attacks and other malicious cyber operations called Grizzly Steppe in order to gain access into networks of U.S. government agencies, critical infrastructure, companies and academic institutions.
Todd Breasseale, assistant secretary for public affairs at DHS, said in an executive summary published Friday that Russian cyber threat actors continued to perform spearphishing operations after the U.S. presidential elections in November.
The document also cited that DHS and the FBI also issued a joint analysis report that offers information on the tools that RIS used to hack networks related to the U.S. election.
DHS also listed several questions designed to help organizations assess their networks’ cybersecurity posture, such as queries on risk analysis, vulnerability patching, business continuity, staff training, critical information backups and incident response.
The White House on Thursday imposed sanctions against Russia in relation to its involvement in the U.S. presidential elections through an amended executive order.
