The FSB, or Federal Security Service of the Russian Federation, is Russia’s principal domestic security and counterintelligence service and has been implicated in state-directed hostile operations beyond traditional internal security functions. It is widely associated with Russian state activity and has been linked to politically motivated operations including assassination activity abroad. A prominent public attribution concluded there was a strong probability that the FSB directed the poisoning of former officer Alexander Litvinenko in the United Kingdom. The service has also been named alongside the GRU in allegations concerning Russian hacking activity tied to the theft and transfer of politically sensitive emails during the 2016 United States election cycle. Available reporting in this context supports characterization of the FSB as a Russian state actor engaged in espionage and post-exploitation activity, with operations aligned to Russian state interests rather than criminal profit. Its known or alleged activity overlaps with broader Russian intelligence behavior including covert action, intelligence collection, and support to influence-relevant operations. In the supplied facts, the FSB is specifically connected to Russian state-directed assassination activity and to cyber-enabled theft of emails later used for political effect. The actor is therefore best understood as a state security service of the Russian Federation with an espionage-driven mission set.
