Recently a niche programming-oriented website called phpbb.com had its user database hacked into and the passwords for 20,000 members stolen. The hacker who broke in then posted the account info and passwords online for the world to see. And while this is really bad news for those 20,000 unlucky souls, it offers an instructive lesson on password security for the rest of us.
InformationWeek analyzed the hacked password list and found a number of interesting trends in the data, primarily revolving around the fact that most people do exactly what they’ve been told not to do since passwords were first invented.
The most popular password (3.03% of the 20,000) was "123456."
