A former senior official within the Security Service of Ukraine (SBU) has been sentenced to life imprisonment following a conviction for high treason. Colonel Dmytro Kozyura, who previously served as the chief of staff for the SBU’s anti-terrorism center, was found guilty of collaborating with Russia’s Federal Security Service (FSB) to compromise national security.

The investigation, which involved extensive surveillance, revealed that Kozyura had been recruited by Russian handlers as early as 2018. While contact remained dormant for several years, it was re-established in late 2024. During this period, the colonel utilized a clandestine safehouse in Kyiv, equipped with dedicated communication hardware, to transmit classified documents and sensitive intelligence regarding Ukrainian military movements, infrastructure, and leadership to his Russian handlers.

Prosecutors highlighted that Kozyura systematically provided information on the aftermath of Russian missile strikes, including casualty figures, and shared documents marked as state secrets. In response to the breach, the SBU conducted a counter-intelligence operation that allowed them to feed the Russian operative disinformation while simultaneously monitoring Kozyura’s activities. The Shevchenkivskyy District Court in Kyiv ultimately handed down the life sentence, citing the severity of the betrayal under martial law and additional charges related to the illegal handling of explosives.

Key Takeaways

• Colonel Dmytro Kozyura, a former SBU chief of staff, received a life sentence for high treason.
• The official was found to have shared classified military and leadership intelligence with the Russian FSB.
• Ukrainian authorities utilized the compromised official to feed disinformation back to Russian forces before his arrest.

Editor’s Analysis & Impact

The conviction of a high-ranking intelligence officer underscores the persistent and deep-seated nature of the espionage war occurring alongside the physical conflict in Ukraine. For the SBU, this case serves as both a significant security failure and a successful counter-intelligence demonstration. By managing to turn a compromised asset into a conduit for disinformation, the agency showcased a sophisticated approach to neutralizing internal threats. However, the incident highlights the ongoing vulnerability of state institutions to long-term recruitment efforts by foreign intelligence services. Moving forward, Ukraine will likely intensify internal vetting processes and counter-espionage measures to prevent further infiltration of its command structures, as the integrity of its intelligence apparatus remains critical to its defensive capabilities.
