If you haven't already, I would suggest as a precaution that everyone with credit cards put a freeze on your credit. Be proactive with this. Here is a link to a set of recommendations by the NY Times. https://www.nytimes.com/2017/09/10/smarter-living/equifax-hack-what-should-i-do.html?mcubz=0 . Many Other links out there on what to do.
Also be careful and go to another credit bureau like TransUnion or Experion. There have been reports that Equifax is asking folks to wavier their liability from any class action suits regarding the breach, if you ask if you were impacted by the breach. You don't need to know that to put a free on your credit, you only need to suspect you have been compromised.
I really don't know why Equifax didn't have all the data encrypted... very negligent on their part!
