Security Service of Ukraine (SBU)

The Security Service of Ukraine (SBU) is Ukraine's primary internal security and counter-intelligence agency. Since Russia's full-scale invasion in 2022, the SBU has become increasingly involved in operations against Russia, including assassinations, sabotage, and attacks on Russian assets. The SBU is newsworthy due to recent leadership changes, with President Zelenskyy replacing Vasyl Malyuk as head of the SBU. Malyuk, who led daring raids against Russia, reportedly resigned after a meeting with the president. The SBU is also in the news for its alleged involvement in attacks on Russian targets far from Ukraine's borders, such as the reported drone strike on a Russian tanker off the coast of Libya. Additionally, the SBU recently detained a British national accused of aiding Russia's FSB in an assassination plot within Ukraine, highlighting the agency's role in combating Russian influence and activities within the country.
