Report: Russia Develops Untraceable Method to Disable Subsea Cables

A joint NATO operation found evidence that Russia's GUGI has developed a method to disable seabed fiber-optic cables without leaving traces. Russian submarines associated with GUGI were tracked off Svalbard in a trial run simulating the technology; a NATO task force intercepted the exercise. The report follows a UK announcement that it had disrupted Russian plans against subsea cables.

Why it matters: The episode illustrates the hybrid warfare challenge of attribution in attacks on critical subsea infrastructure.
