Read the first post again. He had SSH enabled. Do we need more than that? I believe he gave us plenty of information to get an idea of what's going on. Just because you didn't doesn't mean others didn't either.
Does it matter if someone got access to his box from the LAN versus the WAN? Not really. It doesn't change the fact that his computer was compromised.
Computer security is not a laughing matter. You've gone from saying that this is a hoax, to it all being just a big joke that was done by one of their friends. Are you the OP's spokesman? I think not. Don't speak for him.
If you got your car broken into or vandalized would your first reaction be "It's all just a joke!" No. You'd call the police.
Maybe they don't have the time to start spreading lies and deceit, and doesn't have the time like I do to call you out on it.
I mean come on. You claim that it's all a big hoax, then as soon as I call you out on it you start backpedaling like a Russian circus bear.
