Thanks for the heads up. Sure enough, using Chrome to visit the “secrets” site brings up the warning. Couldn’t find a warning on the FR.com domain after viewing all 5 articles attributed to that site via source URL.
It might have something to do with embedded links. If so, most likely hot linked images. I’d be surprised and dismayed to find actual malware being served up by FR, even through random hot linked images.
Only reports I’ve ever seen of malware on the FR domain have been from people that were already infected by malware modifying pages client-side (inserting ads, likely pulling down even more malware.)
Might be time to consider restricting hotlinked graphics to certain domains (Photobucket, tinypic, and the like) to prevent hotlink graphic shenanigans.
Even then you could post something to tinypic that has malicious code in it. Of course, getting it to execute would be a little more problematic. :)
Still, restricting hotlinks to certain known and (relatively) trusted image hosts would knock out a percentage of attacks right there.
