Has anyone actually calculated the real cost of the major exchange data breaches like Coinbase?

Coinbase breach affected 69K+ users, but I'm curious about the actual financial impact of these things.

I feel like we always hear the number of users affected but never the real dollar cost - lawsuits, regulatory fines, security upgrades, customer compensation, etc.

Has there been any good analysis on what these breaches actually cost? Especially curious about the recent big ones.

When Mt. Gox went down, it was "just" crypto that was lost. But now with mandatory KYC, these breaches mean a lot more... hard to wrap my head around it.
