New undersea cable tech listens for sabotage — can be retrofitted to existing fiber optic lines

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.
