Through the WPAD file, the attacker can point users' browsers to their own proxies and intercept and modify all of WWW traffic. Although a simplistic fix for Windows WPAD handling was applied in 2005, it only fixed the problem for the .com domain. A presentation at Kiwicon showed that the rest of the world was still critically vulnerable to this security hole, with a sample domain registered in New Zealand for testing purposes receiving proxy requests from all over the country at the rate of several a second. Several of the wpad.tld domain names (including COM, NET, ORG, and US) now point to the client loopback address to help protect against this vulnerability, though some names are still registered (wpad.co.uk).
