The line 'RedirectMatch (.*)\cmd.exe$ http://127.0.0.1' goes into your
httpd.conf file; that is correct. You must restart the httpd service afterwords
I added additional lines:
RedirectMatch (.*)\root.exe$ http://127.0.0.1
RedirectMatch (.*)\default.ida$ http://127.0.0.1
I took a count before this was in effect:
33998 9:17AM Wed. 26
35214 8:35AM Thur. 27
So no I have not seen it drop off yet, but I guess next I'd like to find out if
there are returning hosts. This morning the LEDs on the cable-modem seemed a
bit quieter but not much.
Testing the operation out; I tried to get example: root.exe from my web server
and was denied and logged still but it didn't give me a 404 page.
So what does an infected IIS machine get now? Maybe one could just grep out all
the hosts with the infection and just add them to the firewall. Would that help
