Microsoft Debuts "URL Tracer" to Halt Typo-Squatters

http://news.yahoo.com/s/zd/20060407/tc_zd/175308

The lightweight prototype, called Strider URL Tracer, builds on the work within Microsoft's Cybersecurity and Systems Management group to keep tabs on a sophisticated typos-quatting scheme that uses multilayer URL redirection to make money from Google's AdSense for domains program

Yi-Min Wang, who heads up the group's work in Redmond, Wash., said URL Tracer can be used as a parental control tool to block inappropriate ads from being served from Web sites that are set up to deliberately lure kids who accidentally misspell a popular domain.
