<p>The Federal Security Service of the Russian Federation (FSB) is the principal security agency of Russia and the main successor agency to the Soviet Union's KGB; its immediate predecessor was the Federal Counterintelligence Service (FSK), which was reorganized into the FSB in 1995. The three major structural successor components of the former KGB that remain administratively independent of the FSB are the Foreign Intelligence Service (SVR), the Federal Protective Service (FSO), and the Main Directorate of Special Programs of the President of the Russian Federation (GUSP).<br/>The primary responsibilities are within the country and include counter-intelligence, internal and border security, counterterrorism, surveillance and investigating some other types of serious crimes and federal law violations. It is headquartered in Lubyanka Square, Moscow's center, in the main building of the former KGB. The director of the FSB is appointed by and directly answerable to the president of Russia. Being part of Russia's executive branch formally, the FSB has significant, if not decisive, power over it.<br/>In 2003, the FSB's responsibilities were expanded by incorporating the Border Guard Service and a major part of the Federal Agency of Government Communication and Information (FAPSI); this would include intelligence activities in countries that were once members of the Soviet Union, work formerly done by the KGB's Fifth Service. The SVR had in 1992 signed an agreement not to spy on those countries; the FSB had made no such commitment.</p>
<p>History</p>
<p>Initial recognition of the KGB<br/>The Federal Security Service (FSS; Russian: Федеральная служба безопасности Российской Федерации, romanized: Federal'naya sluzhba bezopasnosti Rossiyskoy Federatsii (FSB), IPA: [fʲɪdʲɪˈralʲnəjə ˈsluʐbə bʲɪzɐˈpasnəstʲɪ rɐˈsʲijskəj fʲɪdʲɪˈratsɨɪ] [ФСБ, ФСБ России], lit. 'Federal Service [of] Safety') is one of the successor organizations of the Soviet Committee of State Security (KGB). Following the attempted coup of 1991—in which some KGB units as well as the KGB head Vladimir Kryuchkov played a major part—the KGB was dismantled and ceased to exist from November 1991.<br/>In December 1991, two government agencies answerable to the Russian president were created by President Yeltsin's decrees on the basis of the relevant main directorates of the defunct KGB: Foreign Intelligence Service (Russia) (SVR, the former First Main Directorate) and the Federal Agency of Government Communications and Information (FAPSI, merging the functions of the former 8th Main Directorate and 16th Main Directorate of the KGB). In January 1992, another new institution, the Ministry of Security, took over domestic and border security responsibilities. Following the 1993 constitutional crisis, the Ministry of Security was reorganized on 21 December 1993 into the Federal Counter-Intelligence Service (FSK). The FSK was headed by Sergei Stepashin. Before the start of the First Chechen War's main military activities, the FSK was responsible for the covert operations against the separatists led by Dzhokhar Dudayev.</p>
<p>Creation of the FSB</p>
<p>In 1995, the FSK was renamed and reorganized into the Federal Security Service (FSB) by the Federal Law "On the Federal Security Service" (the title of the law as amended in June 2003) signed by the president on 3 April 1995. The FSB reforms were rounded out by decree No. 633, signed by Boris Yeltsin on 23 June 1995. The decree made the tasks of the FSB more specific, giving the FSB substantial rights to conduct cryptographic work, and described the powers of the FSB director. The number of deputy directors was increased to eight: two first deputies, five deputies responsible for departments and directorates and one deputy director heading the Moscow City and Moscow regional directorate. Yeltsin appointed Colonel-General Mikhail Ivanovich Barsukov as the new director of the FSB. In 1998, Yeltsin appointed Vladimir Putin, a KGB veteran who would later succeed Yeltsin as federal president, as director of the FSB. Putin was reluctant to take over the directorship, but once appointed conducted a thorough reorganization, which included the dismissal of most of the FSB's top personnel. Putin appointed Nikolai Patrushev as the head of FSB in 1999.</p>
<p>Role in the Second Chechen War<br/>After the main military offensive of the Second Chechen War ended and the separatists changed tactics to guerilla warfare, overall command of the federal forces in Chechnya was transferred from the military to the FSB in January 2001. While the army lacked technical means of tracking the guerrilla groups, the FSB suffered from insufficient human intelligence due to its inability to build networks of agents and informants. In the autumn of 2002, the separatists launched a massive campaign of terrorism against the Russian civilians, including the Dubrovka theatre attack. The inability of the federal forces to conduct efficient counterterrorist operations led to the government to transfer the responsibility of "maintaining order" in Chechnya from the FSB to the Ministry of Internal Affairs (MVD) in July 2003.</p>
<p>Putin reforms</p>
<p>After becoming president, Vladimir Putin launched a major reorganization of the FSB. First, the FSB was placed under direct control of the president by a decree issued on 17 May 2000. The internal structure of the agency was reformed by a decree signed on 17 June 2000. In the resulting structure, the FSB was to have a director, a first deputy director and nine other deputy directors, including one possible state secretary and the chiefs of six departments: Economic Security Department, Counterintelligence Department, Organizational and Personnel Service, Department of activity provision, Department for Analysis, Forecasting and Strategic Planning, Department for Protection of the Constitutional System and the Fight against Terrorism.<br/>In 2003, the agency's responsibilities were considerably widened. The Border Guard Service of Russia, with its staff of 210,000, was integrated to the FSB via a decree signed on 11 March 2003. The merger was completed by 1 July 2003. In addition, The Federal Agency of Government Communication and Information (FAPSI) was abolished, and the FSB was granted a major part of its functions, while other parts went to the Ministry of Defense. Among the reasons for this strengthening of the FSB were the enhanced need for security after increased terror attacks against Russian civilians starting with the Moscow theater hostage crisis; the need to end the permanent infighting between the FSB, FAPSI and the Border Guards due to their overlapping functions; and the need for more efficient response to migration, drug trafficking and illegal arms trading. In addition, the FSB was the sole power base of the new president, so the restructuring strengthened his position (see Political groups under Vladimir Putin's presidency).<br/>On 28 June 2004, in a speech to high-ranking FSB officers, Putin emphasized three major tasks of the agency: neutralizing foreign espionage, safeguarding the economic and financial security of the country, and combating organized crime. In September 2006, the FSB was shaken up by a major reshuffle. Combined with some earlier reassignments—most notably those of FSB Deputy Directors Yury Zaostrovtsev and Vladimir Anisimov in 2004 and 2005—the changes were widely believed to be linked to the Three Whales Corruption Scandal that had slowly unfolded since 2000. Some analysts considered the changes to be an attempt to undermine FSB Director Nikolay Patrushev's influence, as his team from the Karelian KGB Directorate of the late 1980s to early 1990s suffered most, and he had been on vacations during the events.<br/>By 2008, the agency had one Director, two First Deputy Directors and five Deputy Directors. It had the following nine divisions:</p>
<p>Counter-Espionage<br/>Service for Defense of Constitutional Order and Fight against Terrorism<br/>Border Service<br/>Economic Security Service<br/>Current Information and International Links<br/>Organizational and Personnel Service<br/>Monitoring Department<br/>Scientific and Technical Service<br/>Organizational Security Service</p>
<p>Counterterrorist operations</p>
<p>Beginning with the Moscow theater hostage crisis in 2002, Russia was faced with increased levels of terrorism. FSB Spetsnaz units Alpha Group and Vympel played a key role in hostage rescue operations during the Moscow theater siege and the Beslan school siege. Their performance was criticised due to the high number of hostage casualties. In 2006, the FSB killed Shamil Basayev, who was behind the Beslan tragedy and several other high-profile terrorist acts. According to the FSB, the operation was planned over six months and made possible due to the FSB's increased activities in foreign countries that were supplying arms to the terrorists. Basayev was tracked via surveillance of this arms trafficking. He and other militants were preparing to carry out a terrorist attack in Ingushetia when FSB agents destroyed their convoy; 12 militants were killed.<br/>During the last years of the Vladimir Putin's second presidency (2006–2008), terrorist attacks in Russia dwindled, falling from 257 in 2005 to 48 in 2007. Military analyst Vitaly Shlykov praised the effectiveness of Russia's security agencies, saying that the experience learned in Chechnya and Dagestan had been key to the success. In 2008, the American Carnegie Endowment's Foreign Policy magazine named Russia as "the worst place to be a terrorist" and highlighted especially Russia's willingness to prioritize national security over civil rights. By 2010, Russian forces led by the FSB had managed to eliminate the top level leadership of the Chechen insurgency, except for Dokka Umarov.</p>
<p>Increased terrorism and expansion of the FSB's powers</p>
<p>Starting from 2009, the level of terrorism in Russia increased again, particularly suicide attacks. Between February 2005 and August 2008, no civilians were killed in such attacks. In 2008, at least 17 were killed, and in 2009 the number rose to 45.<br/>In March 2010, Islamist militants organised the 2010 Moscow Metro bombings, which killed 40 people. One of the two blasts took place at Lubyanka station, near the FSB headquarters. Militant leader Doku Umarov—dubbed "Russia's Osama Bin Laden"—took responsibility for the attacks.<br/>In July 2010, President Dmitry Medvedev expanded the FSB's powers in its fight against terrorism. FSB officers received the power to issue warnings to citizens on actions that could lead to committing crimes and arrest people for 15 days if they fail to comply with legitimate orders given by the officers. The bill was harshly criticized by human rights organizations.</p>
<p>Role in Ukraine<br/>Since 2014, the FSB devoted substantial resources in preparing for a Russian takeover of Ukraine. Although Russia's SVR and GRU (foreign and military intelligence services) were also involved, FSB had a lead role on "intelligence and influence operations".<br/>The FSB's Fifth Service, also referred to as the "Department for Operational Information" and "Operational Information and International Relations Service" is stated by the BBC and Radio Free Europe as counterintelligence in former territories of the Soviet Union, work formerly done by the KGB's Fifth Service. Its Ninth Directorate of the Fifth Service targets Ukraine. Putin was persuaded to invade Ukraine by a small group of his closest associates, especially Nikolai Patrushev, Yury Kovalchuk and Alexander Bortnikov. According to some experts, Bortnikov played a key role in Putin's decision to invade Ukraine.</p>
<p>According to a report of the Royal United Services Institute citing interviews of officers and analysts of Security Service of Ukraine, the FSB Ukraine team greatly expanded in July 2021, and by February 2022 it had "around 200 officers" although most teams consist of only 10–20. Before the 2022 invasion, intelligence agencies in Ukraine, Germany, the UK, and the US reported that the FSB planned to replace elected leaders of Ukraine with Ukrainians living in Russia.<br/>In 2014, according to a Russian military analyst, the FSB badly misled Putin with claims that Ukrainians would welcome a Russian invasion of Crimea to free them from "fascists". According to Radio Free Europe, in 2022, the FSB again promised easy victory if Russia invaded Ukraine.</p>
<p>Since the start of the 2022 Russian invasion of Ukraine, Ukrainian counterintelligence has repeatedly asserted that the FSB suffered failures of operations security, including acts of insubordination and possible sabotage. In March 2022, Russia's encrypted communication system in Ukraine became useless after the Russian military destroyed cellphone towers; unencrypted phone calls from the FSB in Ukraine to superiors in Moscow discussing the death of Vitaly Gerasimov were tapped and released publicly. Ukrainian intelligence reported that FSB members were leaking intelligence to them, including the location of the Chechen commandos sent to assassinate Zelensky. In late March, Ukrainian intelligence posted online the names, addresses, phone numbers, and more of 620 people they identified as FSB agents. None of these reports have been confirmed by the FSB.<br/>Media outlets of Ukraine, its allies in the West, and Russian dissidents report that Vladimir Putin has blamed setbacks in the military operations on the FSB and the Fifth Service. On 11 March 2022, investigative journalist Andrei Soldatov reported that Fifth Service head Sergey Beseda and his deputy, Anatoly Bolyukh were under house arrest due to Putin's discontent with intelligence failures regarding the invasion of Ukraine. A U.S. official interviewed by The Wall Street Journal described the arrest report as "credible".<br/>On 11 April 2022, the Times of London, citing unnamed sources who had spoken to Bellingcat executive director Christo Grozev, reported that Beseda was transferred to Lefortovo Prison, the scene of mass executions during Stalin's purges. The same report claims that up over 100 FSB agents from the Fifth Service had been sacked. The Times of London also reports that "it is thought that" the Fifth Service is now headed by Beseda's former subordinate, Grigory Grishaev.</p>
<p>According to an article in the 11 April 2022 issue of The Washington Post:Several current and former officials described the Russian security service as rife with corruption, beset by bureaucratic bloat and ultimately out of touch. A Ukrainian intelligence official said the FSB had spent millions recruiting a network of pro-Russian collaborators who ultimately told Putin and his top advisers, among them the current FSB director, what they wanted to hear.<br/>A series of alleged leaked letters from FSB analysts, made public after the invasion began, report the same kind of problem. For example: "You have to write the analysis in a way that makes Russia the victor ... otherwise you get questioned for not doing good work."<br/>Russian-American ballet dancer Ksenia Karelina was arrested in early 2024 in Yekaterinburg and charged with "treason" for sending $51.80 to Razom, a New York City-based nonprofit organization that sends humanitarian assistance to Ukraine. The FSB accused Karelina of taking part in "public actions to support the Kyiv regime." She initially faced life in prison, but pleaded guilty and was sentenced to 12 years in prison. <br/>In August 2024, a "counter-terrorism" operational regime under the FSB was introduced in Kursk, Bryansk and Belgorod Oblasts. This means in practice that "movement is restricted, vehicles can be seized, phone calls can be monitored, areas are declared no-go zones, checkpoints introduced, and security is beefed up at key infrastructure sites."</p>
<p>Function</p>
<p>Counterintelligence</p>
<p>In 2011, the FSB said it had exposed 199 foreign spies, including 41 professional spies and 158 agents employed by foreign intelligence services. The number has risen in recent years: in 2006 the FSB reportedly caught about 27 foreign intelligence officers and 89 foreign agents. Comparing the number of exposed spies historically, the then–FSB Director Nikolay Kovalyov said in 1996: "There has never been such a number of spies arrested by us since the time when German agents were sent in during the years of World War II." The 2011 figure is similar to what was reported in 1995–1996, when around 400 foreign intelligence agents were uncovered during the two-year period.<br/>In a high-profile case of foreign espionage, the FSB said in February 2012 that an engineer working at the Plesetsk Cosmodrome, Russia's main space center for military launches, had been sentenced to 13 years in prison on charges of state treason. A court judged that the engineer had sold information about the testing of new Russian strategic missile systems to the American CIA.<br/>A number of scientists have been accused of espionage and illegal technology exports by the FSB since it was established; instances include researcher Igor Sutyagin, physicist Valentin Danilov, physical chemist Oleg Korobeinichev, academician Oskar Kaibyshev, and physicist Yury Ryzhov. Ecologist and journalist Alexander Nikitin, who worked with the Bellona Foundation, was accused of espionage. He published material exposing hazards posed by the Russian Navy's nuclear fleet. He was acquitted in 1999 after spending several years in prison (his case was sent for re-investigation 13 times while he remained in prison). In August 2021, the FSB arrested plasma physics expert Alexander Kuranov, chief designer of the Hypersonic Systems Research Center (NIPGS in Russian) in St. Petersburg. Kuranov is suspected of passing secret information to a foreigner about hypersonic technology; he oversaw concept design on the Ayaks/Ajax hypersonic aircraft and has run a Russia-US scientific symposium for several years.<br/>Other instances of prosecution are the cases of investigative journalist and ecologist Grigory Pasko, Vladimir Petrenko, who described danger posed by military chemical warfare stockpiles, and Ni</p>
