The SSU Cyber Security Department systematically protects Ukraine’s information and digital security in wartime. Since the start of russia’s full-scale invasion, the SSU Cyber Department has neutralised over 14,000 large-scale cyberattacks and cyber incidents that targeted government resources and critical infrastructure of our state.

This was announced by Volodymyr Karasteliov, Head of the SSU Cyber Security Department, in the documentary film Cyber Shield of Ukraine.

‘The Cyber Security Department is fighting the enemy on several fronts simultaneously. First, we are countering russia’s specialised units and hacker groups affiliated with them. They carry out regular attacks against Ukraine, and during the full-scale war the SSU has repelled more than 14,000 such attempts. Second, we are actively countering the adversary in the information domain, neutralising information and psychological special operations that russia is conducting against Ukraine and its partner states,’ Karasteliov said.

He noted that in 2025 alone, SSU cyber teams repelled more than 3,000 enemy cyberattacks on Ukrainian systems. The vast majority of these attacks were aimed at disrupting digital services or destabilising strategically important enterprises in the energy, transport, and defence sectors.

The documentary Cyber Shield of Ukraine demonstrates how the Security Service counters enemy attempts to infiltrate and block military and government networks, repels DDoS attacks and phishing campaigns, and fights against cyber espionage and digital terrorism.

‘It is important to emphasise that we are not only defending ourselves. Together with our colleagues from the Defence Forces, the SSU is conducting systematic proactive operations in the enemy’s digital space. Ukraine is delivering painful blows to the aggressor state, although we cannot disclose details at this time. What matters is that the SSU Cyber Security Department is doing everything possible to protect Ukraine’s information and digital space,’ Volodymyr Karasteliov summed up.
