An illicit "shadow fleet," often linked to Russia and China, is actively sabotaging critical subsea cables and evading sanctions, imperiling global data and commerce. These vessels exploit outdated international laws and enforcement gaps, employing tactics like AIS blackouts and false flags for plausible deniability. Recent incidents in the Baltic Sea and near Taiwan highlight the escalating threat. Law-abiding nations must establish shared legal frameworks, including boarding stateless vessels and implementing domestic safety zones. A crucial step involves cutting insurance for these vessels, as most reinsurance relies on US and European markets, effectively denying them market access. Protecting 99% of international data demands urgent, coordinated action and political will.
TOPSHOT - The oil tanker "Grinch", suspected of belonging to the Russian's shadow fleet, is seen outside the coast of Martigues near the port of Marseille-Fos on January 25, 2026, as it's surveilled by the French Navy. France on January 25, 2026 took into custody the Indian captain of an oil tanker suspected of belonging to Russia's sanctions-busting "shadow fleet" for the vessel failing to fly a flag, prosecutors said. The 58-year-old captain was in charge of the tanker, the Grinch, which was seized by the French navy in the Mediterranean on January 22, 2026 and is now moored, under guard, at a southern French port near Marseille.

The shadow fleet, aging tankers and cargo ships that break US sanctions and sabotage subsea cables with impunity, are increasingly disrupting global trade and data flows. Russia and China use these vessels to cut cables with plausible deniability, exploiting gaps in international law that hamstring the US and its allies. Law-abiding states must agree on legal and technical frameworks to stop the shadow fleet and protect subsea cables and cross-border data flows.
