These intrusions occurred in 2021 and affected a limited number of entities across Europe, U.S. government agencies, and around 250 Ukrainian victims. The activity has been linked to the threat group APT28, also known as Fancy Bear, Forest Blizzard (formerly Strontium), FROZENLAKE, and Sofacy, which is connected to the Russian General Staff Main Intelligence Directorate (GRU). The National Cyber Security Centre (NCSC) noted that APT28 gained access to vulnerable routers using default and weak SNMP community strings, as well as by exploiting CVE-2017-6742, a remote code execution vulnerability with a CVSS score of 8.8.
