IE7.0 Detector

ha.ckers.org web application security lab

Detects IE7 despite a spoofed user agent by loading a res:// image from the anti-phishing filter: it renders in IE7, while Firefox substitutes a broken-image placeholder whose measurable size gives the browser away. A small demonstration tool accompanies the post.
