Hi, I have a pcre based rule as follow in my rules file, alert udp any any -> any 53 (msg:"MALWARE domain capodeicapi.eu"; pcre:"m/capodeicapi.eu/i"; classtype:trojan-activity; sid:5000968;) The issue I am facing is that this rule also matches for the domain http://capo.eu which it should not match. I am also facing similar problem with more pcre rules such that they match sub string based url of actual rules . I am using snort version 2.9.1. Kindly let me know if I have any problem with snort syntax or pcre usage and how to resolve it. Your help will be highly appreciated. Thanks in anticipation. Regards,Waseem
