Strike that; it's happened again.

EDIT: And suddenly not. Not sure what happened there.

It keeps coming up for me; either there's a problem on my end or the bad code snuck back in.

Yeah, the "Reported Attack Site" keeps coming back for me as well. I was in the middle of creating a new page of mine, but until this is resolved, I'm not sure it's safe to keep doing so.

It's hard for us to track down which ad causes it due to how specific ad delivery is these days. Every individual sees ads tailored to them. Additionally the ads masquerade as legitimate ads, and load java exploits randomly. Browsers like Chrome and Firefox protect you when this code is detected and don't execute it.

We use two ad networks, AdSense and OpenX, they're as large and legitimate as they come and these issues seem to be hitting quite a lot of large sites right now.

I've looked into analyzing the ad code on our end for exploits before it's served but haven't found anything.

Another strange bug has arisen recently. When I switched to my machine using a 4:3 monitor but did not log in, the main wiki site went into a sort of "safe mode" where frames were not used and only basic HTML text was used, making the site very difficult to navigate. This went away when I logged in, but I'd like to know if anyone else has experienced this bug.

That's not a bug, it's the site's default skin.

That sounds like the css file wasn't being served - my guess would be that file was unavailable at that moment for whatever reason and instead you were just getting plain html text.

This is actually concerning me a little.

Yea, it happened again over the weekend. It was the same vector again, an ad from one of our ad providers, openx. Here was their response:

I now have a direct contact within openx to report malicious ads.
