Duh.  Don't use the specific to this worm rules.  Why must you know
which variant that caused you to get owned?  You have to reinstall the
box anyway.

There is a generic TFTP GET rule, you should use that rule and filer out
the tftp traffic that IS allowed on your network and alert on anything

Just because you don't see "DCOM OWNED YOUR ASS!%)*@%" in a rule message
doesn't mean the rule isn't there.  CVE is a good thing.  Use it.
