Yah, this needs a better title.

Changing it to: Tell me your Sbanken bank account no. and I'll tell you how rich you are

Submitters: the HN guidelines ask you to change a title when it is misleading or baity (https://news.ycombinator.com/newsguidelines.html). This one was both. When changing a title, please look for representative language from the article itself. Usually there's a subtitle or a first sentence that says what the article actually is.

And much, much larger than just Norway.
