Who is Sergei Flesh, the man the Russians tried to kill with a suicide bomber?
An assassination attempt was made last night on Serhiy Beskrestnov, an advisor to Ukraine’s Minister of Defense, who is known in the media under the pseudonym “Flash.”
Russian occupation forces used a rocket-propelled variant of the “Shahed” drone to strike his private residence.
Serhiy Beskrestnov is a leading military expert in the fields of electronic warfare (EW) and electronic intelligence (EI).
In early 2025, he officially joined the team at the Ministry of Defense of Ukraine, taking the position of advisor to Minister Mykhailo Fedorov.
He received his education at the Kyiv Military Institute of Management and Communications, graduating in 1997 with a degree in radio and space communications.
He continuously honed his professional skills at leading European centers, where he studied modern GSM standards and radio relay technologies.
Before the start of the war, Beskrestnov had built a successful career in the civilian sector, holding executive positions at telecommunications giants.
He held top management positions at companies that later became the foundation for the operators Kyivstar and Vodafone Ukraine.
With the start of the full-scale invasion in 2022, the expert actively joined the defense of the Kyiv region, collaborating with the Special Operations Forces.
Together with soldiers from the 3rd Special Operations Regiment, he ensured the stable operation of military communications in the most critical sections of the front in the northern part of the region.
The main focus of his current work is advising the military on countering enemy drones and analyzing enemy radio signals.
Serhiy Beskrestnov trains Ukrainian defenders in the effective use of electronic warfare (EW) systems, which is critically important in the current context of technological warfare.
Despite his active support for the army, he remained a civilian specialist for a long time and did not hold any official positions within the Armed Forces of Ukraine.
It was only in 2024 that he headed the non-governmental organization “Center for Radio Technologies” and later moved to the public sector of defense management.
At night, the Russians attempted to kill Defense Minister Advisor Serhiy Flesh.
Why Serhiy Flesh insists on restricting the sale of SIM cards during the war.
Flesh explained the complexity of protecting trains using electronic warfare means.
