If a major credit agency leak didn't do it, I doubt anything will... At least in terms of a large scale event. We went through the likes of melissa and "I love you" and several others around Y2K (and even that). In the end, life goes on for the most part. What people don't see, they're oblivious to and have short term memories on top.
The credit leaks weren’t used in a way that was obvious to consumers. I’m sure identity theft went up, but that’s still an abstract concern to most consumers.
I think it will have to be something large-scale and obviously concerning to consumers. Something like voice calls leaking and being used to create a mass deepfake campaign targeting consumers.
I don’t think people will care until it’s a problem on their doorstep, sending them phone calls and notifications and what not. Identity theft is too abstract, and too “something that happens to old and other people, not me”.
