Vasyl Maliuk
Vasyl Maliuk became Acting Head of the Security Service of Ukraine (SBU) in May 2022 after President Zelensky dismissed his predecessor Ivan Bakanov amid accusations of Russian infiltration of the service. Maliuk oversaw a sweeping reform of the SBU, purging suspected Russian sympathisers and redirecting the agency toward counterintelligence, sabotage operations inside Russia, and drone warfare coordination. Under his leadership the SBU conducted numerous cross-border drone strikes and partisan operations in Russian-occupied territory.

Under Maliuk's leadership, the SBU launched long-range drone campaigns that struck targets hundreds of kilometres inside Russia, including refineries in Saratov and Krasnodar oblasts. Maliuk openly described these operations as a means of forcing Russia to divert air-defence resources away from the front.
