I tried to login to my gmail, hotmail, and facebook accounts today. I could not login to those three because they said that my password is incorrect. So I tried to think what I did yesterday. I only used those three websites on my iPad.
One thing I noticed with iPad's safari is that it does not warn me for suspicious websites like Chrome or Firefox do.
I concluded that either someone hacked my facebook account and found primary email accounts from facebook and hacked my emails (since they all use same passwords) or my iPad has been hacked. Is it possible that my iPad was hacked?
