FSB

The Federal Security Service (FSB) of the Russian Federation is the principal federal executive agency tasked with counterintelligence, internal security, counterterrorism, border protection, and surveillance operations to safeguard national interests. Formed in December 1991 as the Federal Counterintelligence Service and reorganized as the FSB in 1995, it inherited the core domestic functions of the Soviet KGB, excluding foreign intelligence which was assigned to the SVR. Headquartered at the Lubyanka in Moscow, the FSB reports directly to the President and encompasses specialized units for economic security, cyber defense, and military counterintelligence, wielding extensive legal authority including warrantless surveillance and arrests in security matters. Among its reported achievements, the agency has thwarted numerous foreign espionage attempts, including the detection of over 100 Russian citizens acting as agents for foreign powers and the disruption of terrorist networks through proactive operations. The FSB's expansive mandate has positioned it as Russia's most influential security entity, enabling rapid responses to internal threats but also fueling debates over its role in political stability, with documented involvement in suppressing extremism alongside persistent allegations—often from Western governments—of overreach in domestic monitoring and extraterritorial actions that Moscow attributes to defensive necessities.

History

Tsarist and Soviet precursors

The , formally known as the Department for Protecting Public Security and Order, served as the primary Tsarist agency from its establishment in 1881 until the of 1917. Created in response to the of Tsar Alexander II on March 1, 1881, by the revolutionary group , the Okhrana focused on countering political terrorism, subversive activities, and left-wing revolutionary movements through surveillance, infiltration, and suppression. It operated regional branches, including a foreign office in established in 1883 to monitor émigré radicals, and employed techniques such as agent provocateurs and that influenced later security organs. While effective in disrupting plots, the Okhrana's repressive methods, including widespread arrests and exiles, failed to prevent the empire's collapse amid broader social unrest. Following the Bolshevik Revolution, the Soviet regime established the (Extraordinary Commission) on December 20, 1917, under , as its initial secret police to defend the new order against counterrevolutionaries, saboteurs, and class enemies during the . The evolved through multiple reorganizations: in February 1922, it became the (State Political Directorate) as a department of the of the Russian SFSR; in 1923, it was renamed (Unified State Political Directorate) with union-wide authority until 1934; and in July 1934, it merged into the (People's Commissariat for Internal Affairs), which expanded to encompass mass repressions, including the of 1936–1938. During , security functions split, with the (People's Commissariat for State Security) handling from 1941 to 1946, followed by the (Ministry of State Security) until 1953; Stalin's death prompted further restructuring, culminating in the (Committee for State Security) in March 1954, which centralized , , and duties under the . These agencies collectively suppressed , conducted purges estimated to claim millions of lives, and prioritized regime protection over legal norms. The FSB traces its institutional lineage directly to the KGB's domestic security apparatus, inheriting personnel, methods, and headquarters at Lubyanka while disavowing certain Soviet-era atrocities upon its formation in 1995 as the FSK (). Continuity from Tsarist times is evident in shared emphases on surveillance and political policing, with techniques like informant networks reemerging in operations and persisting into practices, though Soviet organs scaled repression far beyond imperial precedents through ideological mass terror. This evolution reflects a persistent tradition of centralized organs for , adapting to ideological shifts from to without fundamental rupture in coercive functions.

Formation and early post-Soviet years (1991–1999)

Following the failed August 1991 coup attempt against , which discredited the , President moved to dismantle the Soviet security apparatus. On November 6, 1991, Yeltsin suspended activities in , and by December 25, 1991, coinciding with the formal dissolution of the USSR, the 's domestic branches were restructured. The Russian portion of the 's and units formed the basis of the (later renamed the Ministry of Security, or MB), established in January 1992 with approximately 200,000 personnel inherited from the . The , headed initially by and then Viktor Barannikov from January 1992 to July 1993, retained much of the KGB's structure, including border guards and government communications, but aimed to shift focus toward and depoliticization. However, amid growing tensions, including allegations of on political figures, Yeltsin dismissed Barannikov in July 1993. The October 1993 constitutional crisis, where armed forces loyal to Yeltsin shelled the parliament, highlighted divisions within security organs, with some MB units supporting parliamentary hardliners. On December 21, 1993, Yeltsin abolished the MB via decree, citing its "unreformable" nature and persistence of KGB-era habits like political , replacing it with the (FSK). The FSK, numbering about 75,000 personnel, narrowed its scope to , excluding broader intelligence and border functions transferred elsewhere. The FSK operated under directors like Nikolai Golushko and later Mikhail Barsukov, focusing on espionage threats from foreign powers amid Russia's economic turmoil. On April 3, 1995, Federal Law No. 40 reorganized the FSK into the (FSB), signed into effect by Yeltsin on April 12, 1995, which restored some MB-era powers including , , and limited foreign intelligence roles while subordinating it directly to the . This expansion addressed rising internal threats, such as and initial Chechen activities. By 1996, under director Nikolai Kovalev, the FSB had about 65,000 staff and began integrating former special units like for high-risk operations. In its early years, the FSB under (director from July 1998 to August 1999) emphasized countering terrorism and corruption, notably during the 1999 apartment bombings attributed to Chechen militants, which involved FSB investigations leading to the Second Chechen War. Despite reform rhetoric, continuity with practices persisted, including personnel overlaps (over 70% of early FSB staff were ex-KGB) and occasional overreach into political monitoring, as critiqued by Russian liberals and Western observers for lacking sufficient democratic controls. Patrushev succeeded Putin in August 1999, setting the stage for further centralization.

Expansion under Putin (2000–present)

Following Vladimir Putin's election as president on March 26, 2000, the FSB experienced substantial growth in its operational scope, funding, and institutional influence, reflecting Putin's background as the agency's director from July 1998 to August 1999 and his emphasis on strengthening federal security structures amid post-Soviet instability. Early reforms centralized power vertically, elevating the FSB's role within the "siloviki" apparatus of law enforcement and intelligence agencies, which collectively expanded to counter regional separatism and oligarchic challenges. Although precise budget figures for the FSB remain classified, overall security spending surged, with the agency benefiting from a massive funding increase that enabled recruitment, technological upgrades, and broader domestic surveillance capabilities. A pivotal organizational expansion occurred in March 2003, when Putin subordinated the Federal Border Guard Service—comprising over 200,000 personnel—to the FSB, integrating border protection duties and enhancing the agency's control over and flows. This merger, part of post-Beslan reforms after the September 2004 school siege, also incorporated elements of the disbanded Federal Tax Police, broadening the FSB's remit to combat and financial crimes linked to organized groups. Legislative changes further amplified these powers: the 2010 law signed by President granted FSB operatives immunity from prosecution for actions deemed necessary in operations, effectively placing them "above the law" in high-threat scenarios. The 2016 Yarovaya amendments, enacted July 7, mandated telecommunications firms to retain user communications data for six months and install FSB-accessible equipment, vastly extending the agency's digital monitoring reach under the guise of anti-terrorism. Under Director , appointed May 12, 2008, the FSB's mandate evolved to encompass proactive against foreign influence and internal dissent, with operations intensifying after events like the 2014 annexation and the 2022 invasion. The agency foiled numerous plots, including over 100 terrorist attacks annually in the , per official reports, while assuming oversight of scientific collaborations abroad via a June 2025 law to prevent technology leaks. However, independent investigations have linked FSB units to targeted actions against critics, such as the August 2020 poisoning of opposition leader , involving a specialized chemical weapons team that tailed him for years; U.S. sanctions in August 2023 targeted implicated operatives. Russian officials consistently deny political motivations, asserting all activities align with lawful counter-threat mandates, though critics highlight a pattern of expanded repression enabling the agency's entrenchment in governance.

Organizational Structure

Leadership and directorate

The Director of the Federal Security Service (FSB) is appointed directly by the and reports exclusively to the President, serving as the agency's highest-ranking official responsible for overall command and policy implementation in national security matters. Alexander Vasilyevich Bortnikov has held this position since May 12, 2008, making him the longest-serving director in the FSB's post-Soviet history. Born on November 15, 1951, in , Bortnikov graduated from the Leningrad Institute of Railway Transport Engineers in 1973 and joined the in 1975, advancing through and roles before becoming Deputy Director and Head of the FSB's Economic Security Service in February 2004. Bortnikov also chairs the National Anti-Terrorism Committee and serves as a permanent member of Russia's Security Council, positions that amplify his influence over coordinated security operations across federal agencies. Under his , the FSB has maintained direct subordination to the presidency, with Bortnikov's tenure coinciding with expanded agency powers in , border protection, and internal threat mitigation, as authorized by . The FSB directorate comprises the Director and multiple First Deputy Directors, who oversee specialized portfolios such as operational coordination, border guards, and internal apparatus functions. Sergei Borisovich Korolev, appointed First Deputy Director in early by presidential decree, handles key and organizational oversight duties. Another First Deputy, Vladimir Grigorievich Kulishov, directs the FSB Service, integrating border security into the agency's core mandate. These deputies manage the central executive apparatus, which includes operational services for counterespionage, , and information protection, though detailed internal hierarchies remain classified to preserve operational secrecy. The directorate's structure emphasizes vertical command from the , with limited public disclosure reflecting the agency's emphasis on confidentiality over transparency.

Key operational units and directorates

The FSB operates through a network of specialized services (sluzhby) and directorates (upravleniya), coordinated from its central apparatus in , which oversees at least 17 entities including nine primary services focused on core security functions. These units handle , border protection, economic safeguards, and counter-terrorism, with regional directorates (upravleniya) implementing operations across Russia's federal districts. The emphasizes compartmentalization to maintain operational secrecy, with direct reporting lines to the director. Counterintelligence Service (Sluzhba kontrrazvedki), led by a , conducts operations to detect and neutralize foreign , including infiltration of sensitive sectors like the military-industrial complex and responses to cyber intrusions targeting state infrastructure. It maintains on potential internal threats and coordinates with other agencies to safeguard . Service for the Protection of the Constitutional System and the Struggle against focuses on preempting extremist activities, monitoring deemed subversive, and dismantling terrorist networks, including those linked to or radical ideologies. This service has been central to operations against groups like Chechen insurgents and affiliates recruiting in . Economic Security Service oversees , combating , in key industries, and threats to state economic interests, such as illicit trade or affecting strategic sectors like energy and defense. It conducts audits and investigations into ministries and enterprises to prevent economic . Border Guard Service (Pogranichnaya sluzhba), under a first , manages Russia's extensive , sea, and air borders, including troop deployments, surveillance systems, and interdiction of , illegal , and cross-border , with over 200,000 personnel as of the early expansions. Military Counterintelligence Service ensures security within the armed forces and militarized units, vetting personnel, countering penetration by foreign agents, and protecting military operations from internal leaks or , extending to oversight of defense contractors. Specialized directorates include the Investigative Directorate, which probes security-related crimes under FSB , and centers like the 16th Center (Tsentr 16), responsible for cyber operations such as signal interception, decryption, and offensive digital capabilities against perceived threats. Supporting units cover operative information gathering, scientific-technical expertise, , and logistics, ensuring integrated operational support.

Mandate and Core Functions

Counterintelligence and internal security

The (FSB) conducts operations to detect, prevent, and suppress and other intelligence activities by foreign states, organizations, or individuals that threaten 's security, as outlined in 9 of No. 40-FZ of April 3, 1995. This mandate encompasses protecting state secrets, including the identification and neutralization of foreign agents operating within , often through , of double agents, and coordination with other agencies. Internal security efforts under this framework target subversion, separatism, and activities aimed at undermining the constitutional order, with operational measures requiring judicial approval for rights-restricting actions, such as searches or detentions, limited to 180 days per ruling. In combating internal threats, the FSB addresses , , illegal arms and narcotics trafficking, and extremist groups that pose risks to public order and state stability, per Article 10 of the same law. These activities involve proactive intelligence gathering and suppression of networks involved in economic or political destabilization, distinct from but complementary to . The service's duties explicitly include safeguarding strategic facilities and information, ensuring that operations prioritize threats with direct implications over routine policing, which falls to other agencies like the Ministry of Internal Affairs. FSB counterintelligence has documented successes in exposing foreign networks; for example, from 1995 to 1996, it uncovered and supervised approximately 400 foreign intelligence operatives and halted the activities of 39 Russian citizens recruited as agents for foreign services, while preventing over 100 attempts by Russians to transmit classified materials abroad, according to FSB director Nikolai Kovalev's statements in official reports. These efforts reflect a focus on threats and penetration of sensitive sectors like and institutions, though self-reported figures from the agency warrant scrutiny for potential inflation amid opaque verification processes. Ongoing operations continue to emphasize vigilance against hybrid threats, including cyber-enabled targeting government and .

Counter-terrorism operations

The FSB's counter-terrorism operations encompass intelligence-led prevention, disruption of networks, and against threats, primarily Islamist from the and ISIS affiliates. These efforts are managed via the FSB's Anti-Terrorist Center, which coordinates with regional forces under counter-terrorist operation (KTO) regimes allowing warrantless searches and detentions in high-threat areas like , , and . Special units under the Center for Special Operations, including the (Directorate "A") for hostage rescue and assaults, and (Directorate "V") for sabotage and nuclear facility protection, execute high-risk interventions. Since the , these operations have focused on neutralizing tied to the and later ISIS, with the FSB reporting the elimination of hundreds of militants through raids and targeted killings in the . Key tactical engagements include the 2002 theater siege in , where 40 Chechen militants seized over 900 hostages; Alpha and forces stormed the building on October 26 using fentanyl-based gas to incapacitate the attackers, killing all terrorists but resulting in 130 hostage deaths from gas and gunfire. In the September 1–3, 2004, , 32 attackers (including and Ingush) held 1,100 hostages, mostly children; FSB Alpha units joined the chaotic assault on the third day after explosions, eliminating the militants but causing 334 total deaths, with critics attributing high casualties to poor planning and indiscriminate fire. These operations, while ending immediate threats, highlighted tactical challenges like collateral damage from gas deployment and delayed responses. Preventive actions have emphasized foiling plots and curbing . In the 2000s–2010s, amid rising Chechen-led , the FSB dismantled cells planning attacks, reporting major foils in 2005 via intelligence on explosives caches. By 2015, FSB Director stated prevention of numerous "terrorism crimes" linked to ISIL-aligned groups, which comprised most active threats. Against ISIS, operations targeted and Syria-bound fighters from the (hundreds joined by 2014), including arrests of recruiters; a December 2017 raid foiled a plot by detaining suspects with explosives for attacks in . Recent successes include 2024 arrests in and of individuals planning strikes and recruiting for banned groups, amid FSB claims of reduced terrorist incidents through enhanced border and migrant monitoring. Independent verification of prevention statistics remains limited, with some analyses suggesting FSB overstatements of independent threats versus staged incidents.

Economic and border security roles

The Federal Security Service (FSB) is mandated to protect Russia's economic interests by countering threats including economic , , , and other activities undermining strategic sectors and national financial stability. This encompasses investigating economic crimes that jeopardize , as outlined in the Federal Law on the Federal Security Service of 1995, which authorizes the FSB to combat offenses in the economic domain posing risks to the state. The agency's Economic Security Service specifically enforces policies such as import substitution to mitigate the impact of , focusing on domestic production of critical goods like equipment and technology. In practice, the FSB's economic role extends to monitoring and intervening in key industries, including and , to prevent foreign influence or internal , though critics argue this has enabled state control over private enterprises under the guise of security. For instance, the service coordinates with other agencies to safeguard in economic operations and suppress illicit financial flows linked to or . Regarding border security, the FSB's Border Service is responsible for defending Russia's land, sea, and air s against illegal crossings, , and territorial encroachments, while ensuring compliance with border regimes. Under Article 11 of the 1995 , this includes preventing unauthorized alterations to border lines and conducting state control over adjacent territories, , the , and to protect natural resources and economic assets therein. The service maintains patrols, systems, and rapid-response units, with authority to regulate biological resources and combat or resource extraction violations in border zones. The Border Service was fully integrated into the FSB in following a presidential decree, consolidating previously separate functions and expanding the agency's operational reach to approximately 170 border posts and detachments nationwide. This merger enhanced coordination between and frontier defense, enabling joint operations against cross-border threats like and flows that could impact . In recent years, the service has intensified efforts along and southern borders amid geopolitical tensions, including the deployment of advanced monitoring technologies to secure over 60,000 kilometers of boundaries.

Notable Operations and Achievements

Foiled terrorist plots and counter-terrorism successes

The (FSB) has claimed numerous successes in preventing terrorist attacks within , primarily targeting Islamist extremist networks and, more recently, plots linked to international groups such as . These operations often involve gathering, , and preemptive arrests, with the FSB reporting the neutralization of cells planning bombings, shootings, or other assaults on and . Official statistics from FSB briefings indicate significant preventive actions, though independent verification is limited due to the classified nature of operations and from Western analysts regarding potential exaggeration for domestic . In 2011, the FSB reported preventing 94 terrorism-related crimes, including the foiling of eight planned attacks, among them a suicide bombing targeting a high-speed train in the . This effort contributed to a broader decline in successful terrorist incidents during that period, amid heightened measures following the . Similar annual disclosures highlight the agency's role in dismantling recruitment pipelines for groups like the , with operations yielding arrests of operatives handling explosives and propaganda materials. More recent operations include the March 3, 2025, neutralization of a suspect in a plot to conduct attacks and join an international terrorist organization, during which the individual was killed in a confrontation with FSB forces. On October 6, 2025, the FSB announced the prevention of multiple plots targeting Jewish religious sites in two regions ahead of the anniversary, arresting three individuals affiliated with a banned terrorist group who possessed weapons and explosives. These actions were framed as countering ISIS-inspired threats, with evidence including communication records and bomb-making components seized during raids. In October 2025, the FSB further disrupted an ISIS-linked cell planning an attack on a senior defense official, arresting four suspects in with ties to coordinators in and ; seized items included detonation devices and ideological materials. Such interventions underscore the FSB's focus on transnational jihadist threats, though critics note the overlap with geopolitical conflicts, potentially blurring lines between and state-sponsored sabotage. Despite these claims, the March 22, 2024, Crocus City Hall attack, which killed over 140, highlighted gaps in perimeter security, prompting internal reviews but not diminishing assertions of overall preventive efficacy.

Responses to major threats (e.g., Chechen wars, ISIS recruitment)

The FSB's counterterrorism efforts during the Chechen conflicts focused on intelligence gathering, special operations, and coordination with military forces to neutralize separatist insurgents, many of whom employed terrorist tactics. In the Second Chechen War, initiated in August 1999 following apartment bombings attributed to Chechen militants, the FSB's inherited KGB-era units, including the and , conducted high-risk raids and eliminations of rebel leaders in urban and mountainous terrains. These units, part of the FSB's Directorate of Anti-Terrorism Special Operations Center, were instrumental in operations that disrupted supply lines and command structures, contributing to the gradual stabilization of the region by the mid-2000s. The FSB maintained a regime in until April 2009, when it was officially lifted after years of operations that reportedly prevented dozens of major attacks and led to the neutralization of thousands of insurgents. FSB intelligence played a key role in preempting bombings and ambushes, though the agency faced criticism for heavy-handed tactics amid high civilian casualties estimated in the tens of thousands during the wars. By installing pro-Moscow leadership like , the FSB shifted toward co-opting local forces for ongoing security, reducing overt insurgency but sustaining low-level threats into the . Regarding ISIS recruitment, the FSB responded to the exodus of an estimated 5,000–7,000 Russian citizens, predominantly from the republics like and , who joined the group in and between 2013 and 2018 by enhancing domestic surveillance of radical networks. Operations targeted online , mosque-based , and returnee fighters, with the FSB claiming to have thwarted over 500 terrorist acts annually in the through arrests of recruiters and dismantlement of cells. A notable success occurred on , 2016, when FSB forces killed Rustam Aselderov, the ISIS-appointed of the province (Wilayat Qawqaz), in a that disrupted local command. FSB strategies emphasized border controls to prevent to conflict zones and post-return monitoring, leading to preemptive detentions that curbed domestic plots inspired by ideology. Despite these measures, vulnerabilities persisted, as evidenced by ISIS-claimed attacks like the 2017 St. Petersburg metro bombing by a radicalized individual from with ties, highlighting gaps in inter-agency coordination. The agency's focus on ethnic and religious profiling in the yielded empirical reductions in recruitment flows after 2018, correlating with ISIS territorial losses abroad.

Controversies and Criticisms

Allegations of assassinations and poisonings

The (FSB) of has faced allegations of orchestrating assassinations and attempted poisonings of defectors, critics, and opposition figures, often using rare toxins traceable to state-controlled laboratories. Investigations, including analyses and Western government assessments, have linked FSB operatives to a specialized unit handling chemical weapons and , with operations spanning domestic and extraterritorial hits. Russian authorities have consistently denied these claims, attributing incidents to accidents, self-inflicted harm, or unrelated actors. On 1, 2006, former FSB lieutenant colonel , a vocal critic living in exile in , was poisoned with , a rare radioactive isotope, during a meeting at a hotel bar. He died three weeks later on November 23. The UK's 2016 public inquiry determined that the assassination was carried out on the direction of Russia's FSB, with probable approval from President , and likely involved production at an FSB poison laboratory. Suspects and , both former FSB officers, met Litvinenko and were traced via polonium contamination across ; British authorities issued arrest warrants, but Russia refused . In 2021, the ruled that Russia violated Litvinenko's , confirming state responsibility based on the operation's complexity, including procurement of the isotope and travel logistics. In August 2020, opposition activist collapsed on a flight from after being exposed to , a Soviet-era military , confirmed by independent labs in , , and . investigations, corroborated by and , identified at least eight FSB operatives from a chemical weapons unit who shadowed Navalny across for over two years prior to the incident, using vehicles and hotel stays aligned with his movements. The U.S. government assessed that FSB officers administered the , leading to sanctions against four named individuals in 2021. Navalny himself recorded a phone call in December 2020 with FSB officer , who inadvertently described applying the agent to Navalny's underwear; Russian officials dismissed the recording as fabricated. This unit has been implicated in prior poisonings, including those of activists and Leonid Volkov, suggesting a pattern of targeted operations against domestic dissenters. Additional allegations involve FSB surveillance preceding non-poison assassinations, such as the 2015 shooting of opposition leader near the . Open-source data showed Nemtsov was tailed by the same FSB poisoning squad active in Navalny's case, including operatives later linked to multiple hits, though the execution was attributed to Chechen gunmen. In September 2025, further reporting named additional FSB officers connected to Navalny's repeated poisonings, including a fatal attempt in prison in 2024. These cases have prompted and expulsions, with critics citing the use of state-exclusive agents like and as evidence of FSB orchestration, while maintains no involvement and accuses Western intelligence of disinformation.

Domestic surveillance and political suppression

The FSB maintains extensive domestic surveillance capabilities through the (System for Operative Investigative Activities), a legal framework enacted in 1995 that mandates providers to install specialized hardware enabling the agency to intercept phone calls, emails, text messages, , and activity in . This system, expanded under SORM-3 in the , allows FSB access to and with minimal oversight, as operators must route data through FSB-monitored nodes without requiring warrants for initial connections in or contexts. By 2022, disruptions such as Western companies like withdrawing from exposed dependencies in SORM infrastructure but did not halt operations, underscoring the system's entrenchment in Russia's security apparatus. These tools facilitate political suppression by enabling preemptive monitoring and disruption of opposition networks. The FSB has designated anti-corruption groups like Alexei Navalny's (FBK) as "extremist" organizations via court rulings it supports, justifying raids, asset freezes, and arrests of affiliates under extremism statutes (e.g., Article 282.1 of the Criminal Code). In Navalny's case, FSB operatives were linked to his August 2020 poisoning during a flight from , as detailed in investigations tracing the agents' travel and vehicle movements; upon his January 17, 2021, return from , he was detained at an airport under FSB oversight for alleged parole violations, sparking nationwide protests where over 3,650 individuals were arrested across more than 100 cities. FSB operational involvement extends to fabricating or escalating charges against dissidents, including and , often leveraging surveillance-derived evidence. For example, the agency has pursued "" designations and criminal probes against journalists and activists, as seen in the March 2023 arrest of reporter on spying accusations while reporting in , marking the first such detention of a U.S. correspondent since the . Post-2022 invasion of , FSB-led crackdowns intensified, with laws criminalizing "discrediting the military" (Article 280.3) enabling swift suppression; by April 2025, the agency had broadened use of Article 207.3 (false reports) for repressing , resulting in hundreds of pre-trial detentions. Critics, including defectors and leaked internal assessments, argue this reflects a shift from threat neutralization to regime preservation, though FSB officials maintain actions target foreign-backed subversion rather than legitimate political expression.

Human rights concerns and international sanctions

The Federal Security Service (FSB) has been implicated in extrajudicial actions against political opponents, including poisonings attributed to state-sponsored operations. In the 2006 assassination of former FSB officer in via , the ruled in September 2021 that was responsible, citing evidence of an FSB-linked and state approval at a senior level. Similarly, investigations identified FSB operatives in the 2020 Novichok poisoning of opposition leader during a domestic flight, with U.S. intelligence confirming the agency's involvement in the operation's planning and execution. Independent analyses, including geolocation data, also linked an FSB "poison squad" to surveillance preceding suspected poisonings of activist in 2015 and 2017. Domestically, the FSB conducts extensive and initiates cases against perceived threats, often classifying anti-war protesters, journalists, and opposition figures as "extremists" or "foreign agents" under broadened post-2022 , enabling arbitrary detentions and suppression of . U.S. State Department reports document credible instances of , beatings, and coerced confessions by Russian security forces, including FSB investigators, in pre-trial facilities, particularly targeting critics of the conflict or regional separatists in areas like . has noted intensified imprisonment and transnational harassment of vocal opponents, with FSB tactics contributing to a climate of fear through digital monitoring and fabricated charges. In response to these activities, the FSB and its personnel have faced targeted . The imposed sanctions in August 2023 on four FSB officers directly involved in the Navalny poisoning, citing it as emblematic of contempt for , under authorities addressing malign foreign activities. Broader U.S. measures, including June 2022 designations, targeted FSB units for abuses against civilians in occupied territories, such as arbitrary and . The established a dedicated sanctions in May 2024 for internal repression in , enabling asset freezes and travel bans on entities and individuals responsible for violations, with FSB-linked operations falling under scrutiny alongside global frameworks. These measures, coordinated with allies, aim to deter further abuses by restricting access to Western financial systems, though maintains they are politically motivated.

Recent Developments (2020s)

Involvement in Ukraine conflict and annexed territories

The (FSB) played a central role in Russia's pre-invasion operations leading to the full-scale invasion of on February 24, 2022, including preparations for occupation of territories. In 2021, the FSB's Fifth Service was tasked with developing operational plans for potential territorial control, contributing to the buildup of elements such as networks embedded across . These efforts involved recruiting agents and coordinating subversive activities, as evidenced by revelations of FSB-directed cells that surrendered weapons to Russian forces early in the conflict. However, the FSB experienced significant failures, underestimating resistance and over-relying on optimistic assessments of rapid capitulation in , which led to operational setbacks in the initial phases. Following the , the FSB shifted resources almost entirely to wartime priorities, establishing a robust presence in occupied and annexed regions to conduct counter-intelligence, suppress dissent, and secure administrative control. In , annexed in 2014, the FSB has maintained extensive operations, including arrests of local officials under pretexts that critics argue mask , alongside monitoring religious and ethnic minorities to prevent . By 2022, this expanded to the self-proclaimed and People's Republics (recognized by in February 2022) and the annexed and oblasts after sham referendums in September 2022, where FSB units facilitated "" processes to identify and detain suspected loyalists or spies. Russian state media reported FSB-led crackdowns in August 2025 dismantling Ukrainian-backed networks from to , claiming to neutralize dozens of operatives involved in and attacks. In these territories, the FSB coordinates with local proxy forces and (GRU) to counter partisan activities, though inter-agency rivalries have emerged, such as tensions between FSB leaders and GRU-aligned figures in administration. Deployments include elite units like the FSB's Presidential Regiment to frontline hotspots such as in in May 2025, aimed at protecting strategic positions amid heavy fighting. sources report FSB orchestration of assassinations and networks, including a foiled plot against President Zelenskyy in May 2024 involving insiders, while Russian claims emphasize FSB successes in thwarting Western-backed espionage, as directed by President Putin in February 2023 to intensify countermeasures. These operations have strained FSB resources, diverting personnel from domestic duties and exposing vulnerabilities to special operations, such as the 2025 killing of FSB-linked assassins in the region. The FSB's territorial security mandate extends to enforcing legal frameworks in annexed areas, including controls and processing, which have facilitated demographic shifts through coerced passports and deportations. In , FSB operations focus on "" integration, supporting military advances while rooting out infiltration, as stated by officials in February 2025. Despite these efforts, persistent Ukrainian incursions, such as those by the group in , highlight limitations in FSB dominance, with Russian military bloggers dismissing some resistance claims as but acknowledging ongoing threats. Overall, the FSB's immersion in the conflict has prioritized hybrid security over traditional domestic intelligence, reshaping its structure amid high operational demands.

Internal challenges and leaked assessments (e.g., China espionage concerns)

In June 2025, an eight-page internal planning document from the FSB's Department of Counterintelligence Operations (DKRO) was leaked, outlining heightened priorities for countering activities against . The document, authenticated through forensic analysis of its and corroborated by interviews with intelligence sources, explicitly labels as "the enemy" in intelligence operations, revealing stark private suspicions despite public declarations of between and . It details efforts targeting scientists and officials, particularly in the and regions, where operatives pose as personnel from companies or academic institutions to access sensitive military technologies and . The leaked assessment highlights intensification following Russia's February 2022 of , with Chinese agents allegedly seeking to exploit wartime chaos for gains, including analysis of captured Western weaponry and Russian battlefield tactics in . FSB analysts express concerns over China's large-scale apparatus, estimated to dwarf Russia's in and personnel, enabling infiltration of dual-use sectors like semiconductors and hypersonic weapons development. Territorial ambitions are also flagged, with warnings about Chinese mapping of border areas—echoing a 2023 publication that revived historical claims to Siberian territories—and potential resource grabs in the under the guise of joint ventures. This disclosure underscores broader internal strains within the FSB, as resources are stretched thin by the need to balance aggressive monitoring of activities against the imperatives of the Russia-China "no-limits" proclaimed in February 2022. The document prioritizes covert countermeasures, such as feeds to mislead Chinese handlers and restrictions on sharing, without risking diplomatic fallout that could jeopardize economic lifelines like Chinese imports of oil and gas, which surged post-sanctions. Leaks of such sensitive assessments, potentially from insider dissent or cyber vulnerabilities, expose operational fragilities in the FSB's domestic security apparatus, compounded by ongoing demands from the conflict that have diverted personnel and heightened recruitment risks.
