The submarine communication cables form a vast network on the seabed and transmit massive amounts of data across oceans. They provide over 95% of international telecommunications — not via satellites as is commonly assumed. The global submarine network is the “backbone” of the Internet, and enables the ubiquitous use of mail, social media, phone and banking services. To these days no any other technology than submarine cables systems has not been such a strategic impact to our society without being known it as such by the people. This also means that it is at the same time a very interesting destination for hackers, cyber attackers, terrorist and state actors. They seek to gain access to information that goes through the networks of these continents that are connected to each other with sea cables.
