144
145 Dear ${host} administrator,
146
147 Your Microsoft IIS server (at $main::ENV{REMOTE_ADDR}) appears to have
148 been infected with a strain of the CodeRed worm. It attempted to spread
149 to our Web server, despite the fact that we run GNU/Linux and Apache (which
150 are immune).
151
152 You should immediately download the security patch from Microsoft, from
153 <http://www.microsoft.com/technet/treeview/default.asp?url=/technet/itsolutions/security/topics/codealrt.asp>.
154 You can also get information in Japanese from
155 <http://www.reasoning.org/jp/security_alerts/hashsa-2001-02.html>
156
157 And I also suggest that you never use Micro\$oft products
158 for server. It is very ill.
159
160 Regard,
161
162 Webmaster of the Suika server.
163
164 P.S. I attach some information of your request.
