This is probably the 6th or 7th breach I've been of victim of. Honestly, at this point, I just don't care. I have credit monitoring for each of the breaches. I have it through AAA too. I use Mint so I check on my account regularly and would see if there were any fraudulent purchases. I monitor my credit score through Mint and can see if something happens where it takes a plunge. I just can't be bothered to freak out anymore.
^^ That.
Upon notification of yet another breech or leak or loss or whatever-they-call-it-this-time of some or all of my personal data, I sigh, pour a stiff drink, consume said stiff drink, and go on with life.
If my credit score starts taking abnormally (it varies based on how much credit I'm using at any moment - normally zero, sometimes a lot if I'm doing property improvements or helping start a business), I'll look into it.
But the saving grace of this stuff is that using one person's identity or credit card? Super easy. Using ten? Still doable. Using 143 million or whatever the count is up to now? Quite, quite difficult. There's simply no way to scale that kind of identity theft.
I used to care about this stuff. It's happened so many times (I seriously don't even count anymore) that I've just stopped caring. The one thing I cared about credit for (getting a mortgage) was at odds with how we ended up purchasing a house, so... just not going to put that much effort into caring anymore.
