Doubt it. There's no evidence yet that FA's leak was used by malicious hackers. The breach was discovered by some random other person who typed in a different parameter to a URL. Very likely that no one else would've known about it.
Whereas the Equifax situation was intentionally breached by attackers and it can be assumed that the breach was used to capture information for later sale.
I suspect that First American knew about this earlier this week and intentionally did a garbage dump on a Friday evening on Memorial Day Weekend. Maybe trade down a few tenths of a percent on Tuesday and their CISO will probably get axed. Nothing to see here, move along.
I suspect this is going to hit First American pretty hard.
