I had one interesting incident.. I was not able to access my twitter and gamil account both. The twitter account was associated with that gmail account. I had same password for both of them. I was able to recover my gmail as the attacker did not change the recovery email in my gmail account. And hence I could recover the twitter account too. Then again I set the same password for both of them. Next day same thing happened again. Then recovered both and set different password and since then it is fine. I wondered how someone could hack so easily. The passwords were not easy and I can not believe that anyone could guess that. I also checked the last access time in gmail and there were no suspicious activity there.
