I've developed a application rule to detect phishing attempt using fake LinkedIn site.
Don't hesitate to leave any suggestion or comment to enhance this app rule
[Scenario]
Attacker lure a user to click a fake LinkedIn link.
the fake web site looks like a legitimate linkedin login page
the user put his/her linkedin' ID/Password
Attacker get user's id and credential, redirect to original linkedin web site.

I've used an app rule and SEARCH parser.
Rule name: LinkedIn phishing
Rule: extension='php' && match = 'LinkedIn','Linkedin','linkedin'
Dependancy: SEARCH parser
