        Subject: [SAtalk] [EMAIL PROTECTED] virus
        
        

        We're seeing a lot of activity from the [EMAIL PROTECTED] virus
(http://securityresponse.symantec.com/avcenter/venc/data/[EMAIL PROTECTED]
.html)

         

        Could someone help me cobble together a rule quickly to
counteract the attachments it's using.  Something to catch test.zip,
readme.zip and body.zip (the most common ones it appears to be using at
the moment).

         

        Cheers,

        Richard



Hi Richard,
This rule seems to be working fairly well for me, it doesn't grab all of
them, but does seem to get a rather large portion of them....


header   _YM_HS_NOVARG Subject =~ /^(?:hello|test|hi|status|error|server
report|mail delivery system|mail transaction failed)$/i
body     _YM_B_NOVARG /(?:and has been sent as a binary
attachment|partial message is available)/i
meta     YM_M_NOVARG (_YM_HS_NOVARG &&_YM_B_NOVARG)
describe YM_M_NOVARG Message contains virus
score    YM_M_NOVARG 10.0

Watch for line wraps!

HTH,
matt
