A group of Romanian hackers has been arrested for extorting and blackmailing American corporations.
The group would hack corporate databases and systems and then demand payment from the companies in exchange for not disclosing the hack to the media.
Some see the group as a sort of "Robin Hood" organization taking from the big, rich capitalist corporations to give to the poor. I don't think these guys were sharing their loot with the local United Way though so I am not sure they qualify for Robin Hood status.
