I don't know about that. The OPM hack was even worse in terms of data released. Seriously, it included actual images of peoples fingerprints ffs. Along with all biographical information of the people submitted to receive a security clearance background check. I think it may have hit fewer people, but I expect the result will be the same: 18 months of free credit monitoring and after that we pretend that somehow your SSN and all other details must no longer be a threat to you being out in the wild. Sure, in 30 years when someone digs it up and ruins your life with it, why make that OPM agency liable for it? I'm sure they hired top-notch security guys, paid them handsomely, and structured things such that not even the president of the USA could contravene their practices, right? Right?
Oh, a computer was involved. So hire the cheapest person you can find who can half make it work, let even the low level managers do whatever they want, and when it gets hacked blame somebody else. It's computers. NOBODY knows how they work!
