A joint technical alert issued on Monday by the United States and the United Kingdom details how cyberspies believed to be working for the Russian government have abused various networking protocols to breach organizations.
According to the Department of Homeland Security (DHS), the Federal Bureau of Investigation (FBI), and the United Kingdom’s National Cyber Security Centre (NCSC), the
hackers targeted routers, switches, firewalls, and network-based intrusion detection systems (NIDS). Their main targets have been government and private-sector organizations, critical infrastructure operators, and their Internet service providers (ISPs).
“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,” the
report reads.
The first technical report from the DHS and FBI accusing Russia of cyberattacks was the
GRIZZLY STEPPE report published in December 2016. Another technical report
blaming Russia for cyber operations was published in March, when the U.S. accused Moscow of campaigns targeting the energy and other critical infrastructure sectors. The alert on
critical infrastructure attacks was first released in October 2017, but the attacks had not been openly attributed to Russia at the time.
