Cisco Coverage for 'GRIZZLY STEPPE'
Summary: On December 29, 2016, DHS and the FBI released a joint analysis report detailing tools and infrastructure used by adversaries to compromise political, governmental, and private sector entities in the United States, activity the report calls GRIZZLY STEPPE. Cisco Talos said it evaluated the IP addresses listed in the DHS-FBI report, blocklisted the applicable ones, and made coverage available across its security products, services, and open source technologies.
Bottom line: The DHS-FBI report ties this activity to alleged interference with the 2016 U.S. Federal Elections, and Talos's response rests on blocklisting IP addresses from that report - indicators that adversaries can change while the underlying tools and infrastructure remain in use.
