Hmm - if you look at the browser-ID field in the requests concerned, it 
says "MSIE 4.01" or "MSIE 5.5" - the CR II hits that I've been seeing don't 
have a browser ID - so I bet that's why Patrick thinks these are "fake" 
hits, since they're either from a browser, or from software that's 
pretending to be a browser.

The only explanations I can think of are (a) curious people, who wonder 
what happens when they try the exploit using their browsers, or (b) there's 
an infected machine behind a proxy which is masquerading as a browser. I 
think (a) is more plausible, though it seems unlikely that they'd pick on 
random machines - unless Patrick runs a popular system, which might expect 
to be the target of exploration.
