I think it is a real increase in the rate of detected attacks, not just awareness, but whether that’s an increase in vigilance or an increase in attacks is hard to know. I suspect both, of nothing else because awareness drives both vigilance and attackers inspired by the earlier attacks.
I looked pretty hard, with some LLM assistance, so if it was "are we just hearing about it more now" it would have to be old attacks that happened without being discovered and written up.
