Really cool tech and simple tech, tldr, it uses acustics to detect even light touches in the cable; basically it turns cables into guitar strings.

As for sabotage, I don’t know, you could infer what boat caused it maybe? Like the Russian sabotage at the beginning of the war with Ukraine? Doesn’t seem to be much data other than, hey something is touching the cable.

Sabotage by the Deepsea Boys?

I wonder if they can do much with the information other than go “yup cable was fiddled with somewhere on the length of the ocean floor”.
