Some basic statistics on leaked Sony usernames and passwords data.

I spent some time on analyzing password usage using the data that leaked from couple of Sony hacks few days ago. The results are pretty scary.

The data size: 38698 users on 2 sites.

Top ten most used passwords are:

  1. seinfeld
  2. password
  3. winner
  4. 123456
  5. purple
  6. sweeps
  7. contest
  8. princess
  9. maggie
  10. peanut

So if you have a password that is listed above, you better change it pretty soon.

I also compared how many people were using the same password on two different hacked Sony sites. There were 2421 users who used the same email to register and out of those only 168 users were using different passwords (about 6.5%).

And who wins the email war? Based on the same data, most of the users were using emails from the following providers:

# of users Provider
11281 yahoo.com
7250 other email providers
5077 hotmail.com
4876 aol.com
4837 gmail.com
1600 comcast.net
1263 msn.com
920 sbcglobal.net
676 verizon.net
478 bellsouth.net
440 cox.net
