<p>After the Russia-Ukraine war, the Black Sea has become a hybrid security space for both digital and asymmetric warfare within geopolitically integrated competition. Recent attacks by drones on tankers near Türkiye’s Black Sea coastline reflect a sharp shift in the region’s maritime security environment. These new dangers jeopardize key energy and maritime distribution corridors, undermining the resilience of global supply chains. The asymmetric risks posed by autonomous and remotely operated aerial and maritime vehicles and drifting mines further demonstrate the growing threats to commercial tanker operations. Focusing on the recent incidents in the Black Sea and Türkiye’s view of the rising maritime security challenges, this study provides a critical analysis of the economic effects of the hybrid attacks, also considering their legal aspects. It uses a qualitative approach to assess the impact of these security disruptions, drawing on a systematic selection of secondary literature and credible Internet sources. It focuses in particular on the timely verification of information related to the event. It is concluded that the Black Sea has evolved into a hybrid maritime security environment, and the collective security program of coastal states is the most stable solution. It contributes to the literature by demonstrating how localized conflicts reshape energy transport corridors and the stability of critical maritime chokepoints and conceptualizing hybrid maritime security threats.</p>
