Besides the password I use Google two step verification. I also use this on the gmail that I use to authorise computers, anybody knows how this could have happened?

I backed up my wallet to Google Drive.
Could you be more specific on which 2 way authentication you used?
What where the exact steps so we can rebuild the scenario or at least understand what happened exactly.

If it was email by gmail consider the machines you used the blockchain.info/ gmail on as compromised. Most probably all login forms on this machines have been grabbed.
