I encourage you to watch it, and here is a brief personal analysis. This webinar had an immediate merit: amid the numerous publications on the subject (particularly on LinkedIn), and although the topic is not new (especially since the conflict between Russia and Ukraine), it did not treat jamming and spoofing as a purely theoretical issue reserved for specialists, nor from a purely alarmist perspective, but as a now very real operational risk for commercial navigation.

]]>GNSS jamming and spoofing: when a hypothesis gradually becomes a... facthttps://maritimeinfosec.org/gnss-jamming-spoofing-oman-collision/Sun, 15 Mar 2026 10:00:00 +0000Olivier JACQhttps://maritimeinfosec.org/gnss-jamming-spoofing-oman-collision/Over the past few days, there has been a noticeable increase in publications discussing GNSS interference, particularly GPS jamming and spoofing.

This brings me back to a case that is frequently cited in public and private reports, both in France and internationally: the collision that occurred off the coast of Oman between two vessels, which continues to be mentioned as an example of a collision “linked” to GPS spoofing.

What catches my attention is not the hypothesis itself.
GNSS interference in that region is documented and certainly not a new phenomenon. It obviously deserves to be taken seriously.

TL,DR: The BIMCO webinar, held on the 3rd of septembre 2025, was moderated by Jakob Larsen and featured NATO MARCOM officers Eric (French Navy) and Kadir (Turkish Navy) on GPS jamming and spoofing threats to maritime operations. Eric highlighted recent incidents: Ursula von der Leyen’s aircraft disrupted by jamming in Bulgaria, the merchant vessel Green Admire spoofed near Russia, and widespread interference in the Eastern Mediterranean linked to military activity. He emphasized that GNSS disruption is now a deliberate tool of hybrid warfare, not accidental.

]]>Maritime collision and GNSS spoofing: waiting for the facts before drawing conclusionshttps://maritimeinfosec.org/maritime-collision-gnss-spoofing-wait-for-report/Wed, 18 Jun 2025 10:00:00 +0000Olivier JACQhttps://maritimeinfosec.org/maritime-collision-gnss-spoofing-wait-for-report/Only a few hours after the collision between two vessels off the coast of Oman, the first claims attributing the accident to GNSS spoofing (GPS spoofing) began to circulate.

It is likely that we will soon see many screenshots and analyses claiming that GPS spoofing is responsible… or that it is not.

As is often the case with this type of event, it is better to wait for the results of the investigation before drawing conclusions.
