Federal Security Service (Russia) in the context of "Soviet secret police"

There were a succession of Soviet secret police agencies over time. The Okhrana was abolished by the Provisional government after the first revolution of 1917, and the first secret police after the October Revolution, created by Vladimir Lenin's decree on December 20, 1917, was called "Cheka" (ЧК). Officers were referred to as "chekists", a name that is still informally applied to people under the Federal Security Service of Russia, the KGB's successor in Russia after the dissolution of the Soviet Union.

For most agencies listed here, secret policing operations were only part of their function; for instance, the KGB was both a secret police and an intelligence agency.

Cyberwarfare by Russia comprises denial-of-service campaigns, hacking operations, disinformation programs, and state-directed online repression, including participation of state-sponsored teams in political blogs, internet surveillance using SORM technology, and other active measures, executed by Russian security and intelligence agencies since the 1990s to advance Kremlin geopolitical objectives.

Russian doctrine frames these operations within an informatsionnoye protivoborstvo (IPb), or information confrontation, approach that fuses technical network actions with psychological measures. Units of the GRU, FSB, and SVR oversee hacker collectives such as APT28, APT29, Sandworm, Turla, and Star Blizzard that target governments, infrastructure, and civil society across Europe, North America, and Asia.
