Russian GRU DNS-hijacking network targeted military, government, and critical infrastructure sectors worldwide.
The U.S. Department of Justice and the FBI announced a court-authorized operation to disrupt a DNS-hijacking network controlled by GRU Military Unit 26165, also known as APT28 / Fancy Bear / Sofacy, a Russian military intelligence unit. According to the DOJ, the actors compromised thousands of TP-Link small office and home office routers and used them to redirect internet traffic through GRU-controlled DNS resolvers. The purpose of that infrastructure was to enable actor-in-the-middle attacks against selected targets of intelligence interest to the Russian government, including people and organizations in the military, government, and critical infrastructure sectors. The DOJ states that the initial router compromises were broad and indiscriminate, after which the GRU filtered traffic to identify communications worth intercepting. For selected victims, the network served fraudulent DNS records that mimicked legitimate services such as Microsoft Outlook Web Access in order to harvest passwords, authentication tokens, emails, and other sensitive information. It is less suitable for the airspace, maritime, or sabotage categories because the operation was digital rather than kinetic. At the same time, the case is useful for a Europe-focused hybrid-war tracker because the DOJ explicitly says the GRU used the routers against worldwide targets, which means European organizations were plausibly part of the victim environment even if the release does not list specific European countries.
