Probably is, but I've heard of this happening to someone, a friend of the family who is a graduate of John Hopkins with a Masters in IT. Someone tagged his computer somehow, so that no matter how many different IP's he got, how many times he reinstalled windows, he constantly got attacked and compromised. He said and I quote "I'm a graduate of Hopkins University. I owe over $120,000 in student loans. I thought I knew all the s**t. But apparently, I don;t know s**t."
He thought he had hardened his machine, an entire blackhat community somehow found out (Probably through a profile like on myspace) that he was a graduate of IT from Hopkins and broke into the machine, I believe he was also running a honeypot. They took pictures of him off his computer, wearing a swimsuit and put it on the front page of their community website, bragging about it.
This is why I even bothered worrying about it and taking measures, plus posting it up here.
