The team was able to sift out the nodes through which Skype calls are routed and determine the user's real IP address by sniffing the packets. To correlate the identified Skype users with files shared on BitTorrent, the researchers built tools to collect BitTorrent file identifiers, a BitTorrent crawler to collect IP addresses on the network and a verifier to match an online Skype user with an online BitTorrent user (PDF). 'As soon as the BitTorrent crawler detects a matching IP address, it signals the verifier, which immediately calls the corresponding Skype user and, at the same time, initiates a handshake with the BitTorrent client,' they wrote."

If they were criminals, wouldn't they keep their methods secret in order to blackmail or otherwise monetize it in some way? Research like this is the only way that security gets better.

If the researchers can do it, the bad guys may already be doing it.

It should be considering it is the path to the machine that holds all of your personal information.
When you get a key duplicated, a key maker can easily sell a copy of that key, and link it to your name. What if your name is Bill Gates? "This key here is for Bill Gate's personal safe, and this one is for his house, perhaps you would like a copy?"
Just because its available, doesnt mean its not private, or doesnt come with some expectation of privacy. I dont expect the key maker to sell a copy of my key to someone who intends to harm me.
