Cookie variants skirt blockers, antispyware tools
Just because your Web browser is set to block third party tracking cookies that doesn't mean all of them are being blocked.
A growing number of Web sites are quietly resorting to the use of "first party," subdomain cookies to skirt antispyware tools and cookie blockers and allow third party information gathering and ad serving, according to some privacy advocates and industry analysts.
Though the cookies are not fundamentally different from other third-party cookies, they are very hard to detect and block, said Stefan Berteau, research engineer with CA's anti-spyware research team. The result: companies could theoretically use the cookies to quietly gather and share consumer information with little risk of detection, he said.
