Undersea cables carry Internet traffic across continents. They are part of the critical information infrastructure of the modern world.

Scientists started using these cables as a global network of sensors that monitor seismic and other changes at the seabed previously beyond the reach of the scientific community.

With the health crisis, cyber-attacks against civilian infrastructure have multiplied, undermining the fundamental principles of international humanitarian law.
