Hi All,

I’m trying to write a rule to capture email addresses being submitted to a web application and I cant seem to get the regex to work.

alert tcp $EXTERNAL_NET any -> any 80 (msg:"Target Email Detected"; pcre:"/.+\@.+\..+"; fast_pattern:only; nocase; classtype: Target Email Detected ;sid:1000023 ;)

I get the following error when running snort –T:

ERROR: /etc/snort/rules/local.rules Line 30 => unable to parse pcre regex ".+\@.+\..+"

Any help would be greatly appreciated!


Thanks

John.
