Interesting hack, but this seems quite the brazen confession to a fair number of computer crimes. If I were the author, I'd be worried about getting arrested and potentially extradited for this. Especially as he deliberately downloaded a load of confidential information after gaining access, and then shared it around. He'd be looking at years in prison for this, in the US.
Switzerland's federal constitution prohibits extradition of swiss citizens to foreign powers. Now technically, this one amendment can be overriden by a mere act of Parliement, so unless there is a special act I'm not aware of, they are safe.
