there should be a way to reverse these type of transactions when something unauthorized occurs. that's the weakness of BTC right now.
Yeah, that's the same reason why nobody in the world uses cash... huge weakness.
@OP: sorry for your loss. Also, thank you for sharing the information here. It is important that we get to the bottom of this. It's mind boggling. Even if your PC was completely compromised, and you were logged into gox that night, the hacker still needed to long press the yubikey. This is assuming your settings did not leave any holes via API or google auth, etc.
Cash payments are reversible it is called small claims court.
Op i dont shit about the issue you are having but it is screwed up. Goes to show you cant trust institutions.
It makes me sick that this happened to you.
