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 long-range strikes. The SBU is newsworthy due to recent leadership changes, with President Zelenskyy replacing Vasyl Malyuk as head of the organization. Malyuk, who led daring raids against Russia, reportedly resigned after a meeting with the president. The SBU has also been in the news for its alleged attack on a Russian tanker in the Mediterranean Sea and the arrest of a British national accused of aiding Russia's FSB in an assassination plot within Ukraine. These events highlight the SBU's active role in the ongoing conflict and its focus on countering Russian intelligence and operations.
