    Things are getting a little wierd here.
    
    I have been getting some malformed coldered requests, like this:
    
    000.000.000.000 - - [06/Aug/2001:13:06:27 -0300] "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX%u9090%u6858%ucbd3%u7801%u9090%u6858%ucbd3%u7801%u9090%u6858%ucbd3%u7801%u9090%u9090%u8190%u00c3%u0003%u8b00%u531b%u53ff%u0078%u0000%u00=a HTTP/1.1" 400 -
    
    I'm hidding the IP of the source for obvious reasons.
    
    The point is that i looks like a CodeRed II, but it's missing the
    begining of the xploit string. Also, this is a HTTP/1.1 request, while
    regular CRII requests are HTTP/1.0.
    
    I've got these from 2 hosts now. Multiple times from each of these hosts,
    and no regular CRII request from any of them.
    
    Anyone have any idea what this can be ?
