![]() network devices-coupled with a Russian government campaign to exploit these devices-threatens the safety, security, and economic well-being of the United States. Elements from these alerts and advisories have been selected and disseminated in a wide variety of security news outlets and social media platforms. Governments, allied governments, network device manufacturers, and private-sector security organizations. FBI has high confidence that Russian state-sponsored cyber actors are using compromised routers to conduct man-in-the-middle attacks to support espionage, extract intellectual property, maintain persistent access to victim networks, and potentially lay a foundation for future offensive operations.ĭHS, FBI, and NCSC urge readers to act on past alerts and advisories issued by the U.S. This report contains indicators of compromise (IOCs) and contextual information regarding observed behaviors on the networks of compromised victims. This report builds on previous DHS reporting and advisories from the United Kingdom, Australia, and the European Union. Victims were identified through a coordinated series of actions between U.S. This report contains technical details on the tactics, techniques, and procedures (TTPs) used by Russian state-sponsored cyber actors to compromise victims. Targets are primarily government and private-sector organizations, critical infrastructure providers, and the Internet service providers (ISPs) supporting these sectors. This TA provides information on the worldwide cyber exploitation of network infrastructure devices (e.g., router, switch, firewall, Network-based Intrusion Detection System (NIDS) devices) by Russian state-sponsored cyber actors. Original Post: This joint Technical Alert (TA) is the result of analytic efforts between the Department of Homeland Security (DHS), the Federal Bureau of Investigation (FBI), and the United Kingdom’s National Cyber Security Centre (NCSC). For instance, administrators should inspect the presence of protocol 47 traffic flowing to or from unexpected addresses, or unexplained presence of GRE tunnel creation, modification, or destruction in log files. NCCIC encourages organizations to use the detection and prevention guidelines outlined in this Alert to help defend against this activity. Specifically, the industry partner reported the actors redirected DNS queries to their own infrastructure by creating GRE tunnels and obtained sensitive information, which include the configuration files of networked devices. Update: On April 19, 2018, an industry partner notified NCCIC and the FBI of malicious cyber activity that aligns with the techniques, tactics, and procedures (TTPs) and network indicators listed in this Alert.
