Seems like everything we do online, and even offline, has some sort of password to it. One of the first (and most valuable) passwords we all deal with is our bank card's PIN. Many times this is only a 4-digit number, and while usually supplied by your bank or credit union, many of us will change it to something we remember. This can make things easy for someone trying to hack into your account, as things that are memorable tend to be more obvious. A website called DataGenetics, was able to get ahold of 3.4 MILLION PIN's that were stolen and put on the internet, and after analyzing all of the numbers, found some amazing things.
