I have not seen one specific From/To/Subject pattern to catch a rule on. The only thing this virus has in common is a '.exe'. Interestingly enough, it seems that all the really bad worms have attachments that are .bat, .pif, .scr, .exe, or .com. Most of the fairly tame ones hide in other documents. So my little Procmail filter for these attachment *names* has done well catching all of them.
:0 Bw * .*name=.*\.(com|cpl|chm|crt|exe|hlp|lnk|ms[cipt]|ocx|pcd|p[ir]f|scr|sh[bs])( "|$) * ^Content-Transfer-Encoding: base64 FILENAME=| egrep '[ ]name=' | egrep -v '(GENERATOR\>|Microsoft|3D)' | sed 's/.*name= */:/; s/"//g' :0 a fw | formail -A "X-Merlin: Attachment Failed - Binary" I have multiple setups to classify the extension but they all follow the same pattern. You might be able to modify it for your needs. body MY_BAD_ATTACHMENTS /name=.*\.(com|pif|scr|exe|bat)("|$)/i --Larry > -----Original Message----- > From: Forrest Aldrich > This new virus appears to generate many (random?) subjects, > so it's getting difficult to narrow down. > > Has anyone filters for Spamassassin that will correctly identify > this virus?
