I never thought sites so big could possibly get hacked until one day I checked my own site and saw this warning from my FF browser:

reported attack site warning

Obviously the headline is a joke and the recent threats to Facebook/Twitter and Flying Thumbs are not related. Regarding Flying Thumbs, I was able to determine that this was a popular iFrame injection attack that has been used recently. I presume my site was exploited by weak passwords or SQL injection. I thought my passwords were strong because I used a string 12 characters and numbers long with both uppercase and lowercase letters. No part of my passwords are in the dictionary so I’m really unsure of how the password was cracked. I will be sure to change my password every 60-90 days from now on.
