Great news! Equifax also handles one of the foundations of Internet security!

Ummmm.... we are in the year 2017.

You are also exaggerating the "foundations of Internet security" a little bit.

A root certificate authority is not foundational?

It depends on the root certificate. I have personally created a root certificate. I wouldn't expect anyone to trust it.

Do you know what the Equifax certificate is used for?

Even if the Equifax roor certificate were being widely used, I don't see how it would have anything to do with the recent hack. But you haven't even given any reason that this is even noteworthy.

Do you know what root certificates are?

Do you know what GeoTrust is?

https://en.wikipedia.org/wiki/GeoTrust

Sure. So far you have the name "Equifax", a page showing a root certificate that expired 7 years ago and a digital certificate provider named GeoTrust.

What is your point? This is the strangest conspiracy theory I have ever seen.
