One of the ways I handle these types of emails is that I determine who is responsible for the IP address of the machine that sent this message out: If you look in the headers this is: 165.189.17.51 I used a tool on the net called sam spade to determine who is responsible for this IP.

There are links within this page so you can send the network abuse person a message ( or call ) about these problems you are having and they will have something done. http://www.samspade.org/t/lookat?a=165.189.17.51 Lee Lee Duynslager Information Technologist Integrated Plant Systems Michigan State University (517) 432-5296 -----Original Message----- From: MSU Network Administrators Group [mailto:[log in to unmask]] On Behalf Of Tim Potter Sent: Wednesday, May 12, 2004 8:27 AM To: [log in to unmask] Subject: [MSUNAG] Suspect files of zero-length I've been receiving suspicious files of the usual viral extensions (.exe, .scr, .com, etc.) about every day from this same individual (see below) but all of the files have been zero length and not detected by my AV software as infected (Norton AV CE 7.61 and Kaspersky KAV 4.5.0.95 Trial).
