This is old as hell. I remember reading about this years ago. I don't know what else did they hack beside the account. In fact I think it was not even a hack. The gmx account (satoshin@gmx.com or satoshi@gmx.com I dont remember) expired and someone else just registered it, ten claimed to have satoshi's dox.

Of course this was bullshit because satoshi was never hacked, doxed, or compromised in any way.
