I don't know if the author is an UK transplant or just ignorant.

When I read the headline, it said US Bank then the article talks about US Banks.

As in multiple financial institutions. There is a bank called US Bank, so you can see why there is a little bit of confusion.

Considering that US Bank is west coast based, it is a wonder why the author didn't catch this.

With respect to security, this is what you get when you have companies rush to get their presence on the net and higher the cheapest labor they can find. (Ever deal with a bank's procurement process on contracting resources? ;-)
