367,000-Ship Study Finds Global GPS Spoofing, Red Sea Activity Before Grounding

Researchers who analyzed AIS data from more than 367,000 vessels detected 31 persistent geographic zones of abnormal GPS-derived positions—classifying at least 22 areas as strong evidence of large-area spoofing—producing thousands of implausible ship movements across regions including the Red Sea, Strait of Hormuz, Black Sea and Gulf of Mexico; the paper links earlier spoofing near Port Sudan to the May 2025 grounding of MSC Antonia, emphasizes that AIS cannot attribute the source of spoofing, and recommends continuous monitoring and risk maps to warn vessels.
