Hi,
Two things.
One. Some articles even suggested that a lot of the security thing was a problem with their servers using Apache, an Unix based operating system. Per my friend, a security expert and original Open BSD security modules person, the issue was not just Apache, but the quality of the folks working on the Operating System. Most of them were not qualified and not experienced enough to even work with Apache or any Operating System, having been brought up in a time that did not work with Unix a whole lot.
Two. Equifax, is a CASH COW ... and owned by invisible huge companies that are simply collecting free money and they couldn't careless if anyone's information was given out ... that information can easily be acquired anywhere else on the net.
AND, of course, a Cash Cow is never wrong, and if it is, it was no real big deal (they will never admit any problems, because they hide them on a quick fix in Unix), because if it were, a lot more would be involved and a lot bigger issues would have taken place, and a lot more Federal Institutions would be involved in making sure that nothing else got hurt ... notice the bigger players in Microsoft, Apple and other institutions just laughed it off ... sort of like suggesting their systems are better and more secure. They are not any better or more secure, specially Microsoft that is too slow to resolve issues ... even had a rootkit in your system? ... right ... get ready to lose everything and redo your computer. No such chance or luck with Unix, unless it is administered by someone that does not understand the security levels that can be created and added to it. And a lot of Unix was already 64bit before Microsoft and anyone else, and the security was far better ... but it had work done by folks with interest in it, not Microsoft or Apple.
