Hi
Having received our first wild Melissa I have rewritten the filter
slightly as there was a typo in the original! I suggest you to scan
your logs if you just cut and paste my example.
#
if $header_Subject contains "Important Message From" and
$message_body contains
"Here is that document you asked for ... don't show anyone else" then
# ^
# "Here is that document you asked for... don't show anyone else" then
testprint "Melissa header and body part seen from $sender_address"
freeze text
"Melissa header and body part seen. \n \
Message may contain Melissa Word Macro Virus\n $message_headers"
endif
#
I have also increased the configuration value of message_body_visible
from the default of 500 as when we tested the filter internally the
addition of a lot of forwarding information by one MUA from the
headers to the body of the message buried the tell-tale body part.
Given the announcement about polymorphism for word Macro virii
http://www.geek-girl.com/bugtraq/current/1190.html
we are fighting a rapidly losing battle.....
Happy Easter
Ken
