PIN analysis
A good friend of mine, Ian, recently forwarded me an internet joke. The headline was something like:
DISCLAIMER
This article is not intended to be a hacker bible, or to be used as a utility, resource, or tool to help would-be thieves perform nefarious actions. I will only disclose data sufficient to make my points, and will try to avoid giving specific data outside of the obvious examples. I do not want to be an enabler for script-kiddies.
The Data
I was able to find almost 3.4 million four digit passwords. Every single one of the of the 10,000 combinations of digits from 0000 through to 9999 were represented in the dataset.
Cumulative Frequency
As noted above, the more popular password selections dominate the frequency tables. The most popular PIN code of 1234 is more popular than the lowest 4,200 codes combined!
Bottom of the pile
OK, we've investigated most frequently used PINS and found they tend to be predictable and easy to remember, let's turn for a second to the bottom of the pile.
Memorable Years
Many of the high frequency PIN numbers can be interpreted as years, e.g. 1967 1956 1937 … It appears that many people use a year of birth (or possibly an anniversary) as their PIN. This will certainly help them remember their code, but it greatly increases its predictability.
Patterns in data
I love pretty ways to graphically vizualize data. Pictures really do paint thousands of words.
