Hello all,

I am updating some rules to detect phishing sites against our customer and I was
wondering if someone has created a rule set to "disable" search engine impacts.

I was firstly thinking about adding to each rule some pcre, one for each mayor
search engine (google, bing, yahoo,...) but I think this is nonsense.

actually, in your case, that is the way to go...

As second option I though about creating a white list but I have no access to
create it, I am only allowed to create rules.

Any other idea?

in your phishing rules, set a flowbit... then in your rules to detect if it is a 
search engine, unset that flowbit... at the end, one rule to check the 
flowbit... if it is still set, then fire the phishing alert otherwise it is a 
search engine and the phishing alert is not fired...
