Eric Tonight I discovered by chance a clever WordPress hack in the wild which only redirects visitors who reach the site from Google to a spam site but not those who reach it via vanilla URL getting (typing or bookmarks). I'll publish details once the issues been fixed, contacted the owner and got a response. Very clever thing as when I noted the site had been hacked with a link to it the site that link went to the normal website and I looked a doofus.

Mark Dain Sounds interesting. Can this be mitigated by turning off the referer header?
