None of this is new. The Romans encrypted dispatches.
From Renaissance times governments exchanged information with their ambassadors by letter, letters that others were keen to read too. All big states had a ‘Black Chamber’ devoted to intercepting and decoding what their rivals were saying.
Since then telegrams, telephony, wireless, and now the internet have increased the scale of operations, but the principle is the same: the best intelligence comes straight from the source. Diplomatic, military, commercial and personal are all fair game.

This has gone one step further beyond comms intercept and into active sabotage and attack, ie the Hezbollah’s exploding pagers recently.
Fears are that all the Chinese cars could be made to stop on command, bringing traffic nationwide to a standstill if China for whatever reason chose to do so. Or I suppose they could command them all to go full speed then turn hard left into oncoming traffic. Or short circuit the main battery with catastrophic results .
It’s an interesting world we live in.
