Subsea Cables – A Crunchy Target

Submarine cable map

State of (Cyber)War Episode 7.1

Welcome to the first of our two-part episode on underwater communications cables. Hugo Tarrida and John Salomon discuss the history and current situation surrounding the world of undersea comms infrastructure, and try to get a grasp of threats to the data links under our oceans that are an integral part of both civilian and military capabilities.

Notes and Links:

The rapidly evolving conflict in Ukraine, increasing revelations about Russian (and possibly others’) sabotage efforts in Europe and further afield, tensions around Taiwan and the South China Sea, and the Middle East conflict all mean that some of the topics we talk about in this episode may have changed by the time we get around to actually publishing it.

As with all our talks, this is purely based on our own (limited) knowledge and expertise, and a lot of open source intelligence and publicly available material. Feel free to direct any corrections, insults, and additional information to the various comment sections.

03:30 Germany’s Enigma cipher machines, the Polish Byuro Szyfrów, and British Bletchley Park codebreaking efforts are a fascinating rabbit hole – see you next week. The Allies were far from alone in this, albeit having a much better organized, resourced, and mature set of cryptanalytical capabilities compared to even the Germans: https://en.wikipedia.org/wiki/German_code_breaking_in_World_War_II

06:20 Some market statistics and information: https://www.marketsandmarkets.com/Market-Reports/submarine-cable-system-market-184625.html – currently the undersea cables market is worth around 18.2 billion and is expected to grow to 29.7 billion by 2029
