Conficker Eye Chart

April 2nd, 2009

I’ve been working on a few different ways to detect Conficker via a web page load. I originally came up with a javascript method but I decided to go with a simpler approach using only images. Thus, the Conficker Eye Chart was born. It’s a simple visual test you can use to evaluate a Windows PC just by surfing to that page and looking at the images. It doesn’t work if you’re behind a web proxy (since the proxy will resolve the remote sites for you, bypassing Conficker’s blocking ability). But if you are behind a proxy, you should already be getting your Windows updates (including the MSRT tool) on time and updates from your anti-virus company as normal, so you shouldn’t be infected, right?
