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:
- seinfeld
- password
- winner
- 123456
- purple
- sweeps
- contest
- princess
- maggie
- 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 |
