On 10 May 2025, the MSC Antonia became stranded in the Red Sea at Eliza Shoals, a shallow area roughly one hundred nautical miles from the coast, while sailing towards the Saudi port of Jeddah. The vessel listed to one side and efforts to free it using tugboats are still ongoing. The MSC Antonia is a 7,000 TEU container ship registered under the Liberian flag. An analysis of the ship’s navigational track prior to grounding suggests a possible cyberattack involving GPS signal spoofing.
According to maritime intelligence company Windward, the container ship may have received false positioning signals that led it off its intended course and into shallow waters. The erratic movements recorded before the grounding are consistent with this type of interference, which is becoming increasingly common in sensitive commercial traffic zones. The vessel’s AIS track shows irregular patterns inconsistent with a normal commercial route, providing further evidence of digital manipulation of the navigation system.
Confirmation of possible electronic anomalies also came from UK Maritime Trade Operations, which on 9 May reported severe GPS signal disruptions in the area between Jeddah and Port Sudan, in the hours immediately preceding the incident. There is also a broader context: the average distance of these “phantom displacements” caused by GPS interference has risen from around 600 kilometres in the fourth quarter of 2024 to over 6,300 kilometres in early 2025.
This figure reflects a significant escalation in jamming techniques, with the potential to render ships’ satellite navigation systems unreliable. Ami Daniel, CEO of Windward, bluntly described the situation as a “clear and present danger” to navigational safety. Lars Jensen, industry expert and CEO of Vespucci Maritime, stressed that such attacks can no longer be regarded as remote possibilities but rather as real and increasingly sophisticated threats.
Perhaps the most unsettling aspect is how easily spoofing technologies can now be acquired. According to the 2024 report The Great Disconnect produced by Thetius, CyberOwl and HFW, basic equipment can be obtained for under 100 dollars. If such technologies are accessible even to small groups, it is not difficult to imagine what state-backed actors with advanced engineering resources might achieve. In this context, the Red Sea is becoming an unstable testing ground, where ships can be diverted, deceived and endangered without any visible threat.
The MSC Antonia case prompts a broader reflection on modern shipping’s reliance on centralised electronic systems that are easily targeted. Shipping companies now face a dual challenge: on one hand, the urgent need to invest in more resilient technologies capable of withstanding interference; on the other, the revival of traditional navigation skills as a backup in the event of an attack. Striking this balance is difficult but increasingly necessary.
The geopolitical implications of the incident are equally significant. As a Windward analyst pointed out, this is not merely a technical mishap but an event laden with strategic meaning. The ability to disrupt navigation on a regional scale implies the potential to influence — or even block — trade routes vital to the global economy. In a period marked by international tensions and fragile supply chains, maritime security can no longer be separated from the protection of digital infrastructure. In the short term, tighter controls in high-risk areas and increased military patrols are likely. But in the medium to long term, the entire sector will need to rethink its tools, skills and operational standards.
