Surf Jack - HTTPS will not save you

A good friend of mine from enable security has written an nice article on "surf jacking". from the article:
"Say hello to a new security tool called “Surf Jack” which demonstrates a security flaw found in many public sites. The proof of concept tool allows testers to steal session cookies on HTTP and HTTPS sites that do not set the Cookie secure flag. I’ve been working with two banks and some of the vulnerable sites to get this fixed before publishing my research. Mike Perry gave a talk at Defcon involving the exact same vulnerability - so there is no point in keeping this from the public."
