Naval News – Few corners of the submarine world are seen as sneakier than covert operations against undersea communications cables. It is estimated that 97% of global communications are transmitted by undersea cables. This includes trillions of dollars of financial transactions. These cables have been described as ‘Indispensable but insecure’. They are thought to be particularly vulnerable to the Russian Navy’s seabed warfare platforms. And it is not just internet traffic which could be under threat, but energy infrastructure, military communications and sensor networks.
