Robert David Graham writes "The hacker who broke into phpbb.com posted the passwords online. I was sent the password list, so I ran it through my analysis tools and posted the results.

I spent a while googling "159357" trying to figure out how to categorize it, then realized it was a pattern on the numeric keypad. I suppose whereas "1234" is popular among right-hand people, "159357" will be popular among lefties.'"
