You're correct, it should be tcp. Surprised snort hasn't complained about that one. Thanks for pointing it out.

Fixed and posted. Thanks

From today's bleeding-virus.rules:

alert icmp $HOME_NET any -> any 25 
(content:"8FI0MxBcdcOwU0QzEFL0MwBXBDMQWsS2wFIkMxBcdcOgUqQz"; msg:"BLEEDING-EDGE VIRUS 
Netsky base64 port 25"; classtype:trojan-activity; sid:2001283; rev:2; )

I don't understand the 'alert *icmp*'. Netsky is purely SMTP-based,
isn't it?

cheers,
Jamie
