GPS spoofing is increasingly targeting commercial ships, misdirecting vessels by broadcasting false satellite signals. In the Black Sea, ships have been shown appearing to move in perfect circles on tracking maps while remaining hundreds of miles away-clear evidence of manipulation.
The MSC Antonia grounded in May 2025 after its GPS showed it jumping hundreds of miles south in the Red Sea. Navigational confusion led to a costly salvage operation lasting over five weeks.
Modern shipping relies almost entirely on electronic navigation. With paper charts and celestial navigation rarely used, crews lack backup methods when systems fail. Many mariners report no training for cyber threats beyond phishing.
As ships adopt satellite internet like Starlink, digital vulnerabilities grow. Cybersecurity experts warn that military-style resilience practices could help-but are difficult to implement in commercial fleets.
