Cyber Incident Victim: Russian Federation

On September 22, 2023, Ukraine claimed responsibility for a missile strike targeting the headquarters of Russia's Black Sea Fleet in the city of Sevastopol on the occupied Crimean Peninsula. This attack was described as delivering a major blow to Moscow and was part of a string of recent attacks on the strategically significant port. Mikhail Razvozhayev, the Russian-installed governor of Sevastopol, confirmed the headquarters had been hit in an enemy attack. Social media video footage documented the event, showing plumes of thick smoke rising from the Russian naval headquarters complex. The Ukrainian army formally stated on Telegram that its defense forces had launched a successful attack on the headquarters of the command of the Russian Black Sea Fleet in temporarily occupied Sevastopol. The Russian Defense Ministry reported that its historic headquarters were damaged and acknowledged that one serviceman was missing as a result of the strike.

Simultaneously with the missile strike, the Crimean Peninsula was subjected to what was described by Oleg Kryuchkov, an adviser to the Crimea governor, as an "unprecedented cyberattack" targeting its internet providers. This dual physical and cyber assault represented a coordinated effort to disrupt Russian operations in the region. The attack on the naval headquarters occurred within a broader context of intensified Ukrainian operations targeting Russian naval facilities in Crimea. According to analyses from the Institute for the Study of War, these attacks had been increasing in frequency in recent weeks, even as Ukraine's main counteroffensive ground operations in the east and south of the country were making slow gains. Military experts cited the strategic importance of these strikes, noting they were essential for Ukraine to degrade Russian morale and weaken its military capabilities by striking high-value targets behind the front lines.

This incident was not an isolated event but part of a recent pattern of escalated strikes deep into respective territories. The British Defense Ministry, in its daily intelligence update on September 22, characterized the situation as both Russia and Ukraine experiencing "unusually intense" attacks "deep behind their lines." Specifically, over the preceding four days, there had been multiple reports of explosions at Russian logistics sites, air bases, and command posts not only in Crimea but also in the Russian Krasnodar region and in areas near Moscow. The attack on the Sevastopol headquarters came just one day after Russia had conducted a large-scale bombardment of cities across Ukraine. Those Russian strikes involved missiles and artillery, killing at least five people according to reports. Ukrainian officials described the Russian action as a "massive missile attack on the civilian infrastructure of a number of regions."

Specific impacts from the prior day's Russian attacks were detailed by regional officials. In the Kherson region, Governor Oleksandr Prokudin reported a Russian strike hit a residential building, resulting in two civilian deaths and five injuries. In the Ukrainian capital of Kyiv, the head of the city's military administration, Serhiy Popko, stated on Telegram that debris from intercepted Russian missiles fell on the city. Kyiv Mayor Vitalii Klitschko confirmed that this falling debris injured seven people and damaged several buildings. In northeastern Ukraine, the regional governor of Kharkiv, Oleh Syniehubov, reported that at least six Russian strikes hit the city of Kharkiv, damaging civilian infrastructure. In a separate military action, Russia claimed on September 21 to have destroyed 19 Ukrainian drones over the annexed Crimean Peninsula and the nearby Black Sea. The Russian Defense Ministry also stated it had downed three additional Ukrainian drones over the Kursk, Belgorod, and Orlov regions inside Russia.

On the same day as the Sevastopol attack, a significant diplomatic tension between Ukraine and Poland surfaced publicly. Polish Prime Minister Mateusz Morawiecki told Ukrainian President Volodymyr Zelenskyy not to "insult" Poles, maintaining a harsh rhetorical stance towards Kyiv. This comment followed President Zelenskyy's address to the United Nations General Assembly earlier in the week, during which he referenced the "political theater" surrounding the import of Ukrainian grain, a statement perceived as an insult by Polish leadership. The tensions stemmed from Poland's decision to implement a temporary ban on imports of grain from Ukraine to protect its own farmers. Despite the dispute, Polish President Andrzej Duda stated at a business conference on September 22 that he had no doubt the grain issue was an absolute fragment of overall Polish-Ukrainian relations and that the brewing tensions would not significantly affect good bilateral relations. However, the Polish government clarified its position on military support, announcing on September 21 that it would only supply Ukraine with previously agreed-upon deliveries of ammunition and armaments. This statement followed a prior announcement by Prime Minister Morawiecki that Poland would end new weapons transfers to Ukraine as it focused on modernizing its own armed forces.
