On November 3, 2025, Russian and OSINT sources reported a significant AIS spoofing event in the Gulf of Finland in the central Baltic Sea, where more than 40 fictional ships appeared on AIS tracking systems. This digital ‘ghost fleet’ appeared without physical ships present, demonstrating advanced electronic warfare or deception techniques aimed at disrupting maritime domain awareness. The spoofing event raises important questions about maritime security and the risks posed by manipulation of AIS data, which is critical for navigation safety. The incident reflects an emerging tactic in hybrid warfare in the Baltic region.
