I'm kind of partial to: file_data; content:"<iframe "; nocase; content:"visibility|3a|hidden"; within:100; nocase; pcre:"/\x3ciframe[^\x3e]+[heigwdth]{5,6}[^\x3d]*?=[0-1][^\d]/i"; Not really sure though how to make that one performance friendly since the PCRE engine may be invoked often. Either way, good conversation James and Alex, I believe this theme to be very useful. ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
