Zombie Cookies Just Won't Die 189

Posted by CmdrTaco from the zombie-want-caaaaache dept.
GMGruman wrote in to say "Microsoft embarrassed itself last week when it got caught using 'zombie cookies' — a form of tracking cookies that users can't delete, as they come back to life after you've 'killed' them. Microsoft says it'll stop the 'aberrant' practice. But Woody Leonhard says you ain't seen nothing yet. It turns out HTML5 offers a technical mechanism to give zombie cookies a new lease on life — and the Web browsers' private-browsing features can't stop them."

      Is there any good reason why one would want to use HTML5 at all? I mean, as a user?

      That's a very fair question, but it's a slightly loaded one. As a user, there is little benefit to any particular web technology, whether it's HTML, CSS, JavaScript, Flash or anything else. As a user, what you care about is results. However, those results depend on what developers can build, typically within a certain amount of time and budget.

      If you have new technologies that allow developers to do new things, and those things benefit the user, then the user wins. However, if you have new technologies that allow developers to do old things in newer, easier, faster ways, and those things benefit the user, then the user also wins, particularly if it becomes viable for developers to make something useful in a cost-effective way when they could have done it before but didn't because it was too expensive in some respect.

      And from that point of view, HTML5 tools like canvas and media tags are a big step up for some jobs over using something like Flash or Java applets.

      That said, I strongly agree that browsers shouldn't be ceding any sovereignty over their users' systems to remote code by default.

      And that said, the most devious tracking mechanism I have yet encountered didn't rely on any sort of cookie/local storage technology. It was essentially based on how various web-related protocols handle caching, it's hard to defeat without getting rid of caching, and you really don't want to get rid of caching. It is possible for browsers to avoid falling into the trap, and now that the attack vector has been identified I expect they'll do something about it.

      Then again, as you read this your browser is probably advertising an almost unique fingerprint that could track you anywhere on the Web without storing anything on your machine at all, every time it sends request headers, and despite this being a well-known problem for quite some time, the browser developers haven't done much about it yet. Until they do, fighting against tricky little local storage vectors is hitting the 1% problem, not the 99% problem...

      • Double plus on your last paragraph -- browser headers are really really unique at this point: http://panopticlick.eff.org/ [eff.org]

    OK so the article cites localStorage as a problem, but Chrome at least treats it the same as cookies when clearing private data, and in incognito it shouldn't persist localStorage data across sessions (not sure about other browsers).

    It also mentions that MS was sticking a JS file in the browser cache to recreate a cookie. This doesn't make sense since any file removed from the cache is just redownloaded, unless a custom version of the JS file is crafted for every client and is set to create a specific cookie value (but this isn't clarified in the article). But it sounds more like ETags are used, having nothing to do with the JS file being cached or not. I'm not sure how ETags work but I can't imagine they would be effective in incognito mode either since cache is never kept (and the article infers this is necessary).

        It was about using browser cache as storage medium by doing some neat tricks on the server to get the browser to keep a javascript file in cache, which inturn functions as a cookie when used by various pages that reference it.

        Page requests cookie.js, the server then serves cookie.js with a cache expiry of a hundred years into the future, and says it hasn't changed in a hundred years either.

        Your browser caches it and then doesn't request a new copy for a 100years, why should it, it was told the file isn't going to change.

        The data in the file now serves as a unique ID which can be used to associate your browsing habits.

      Self interest explains this. If cookies cease to `work' for the purposes of the ad networks then they'll make sites cease to work for those of us that thwart them. They're footing the bill for a lot of the `Internet', including the site you're reading now, so they call the shots. Since cookies still work for their purposes I get what I want with little bother, while everyone else has their every click correlated to their profile.

      I don't want some grand solution that puts everyone at parity with me, becau

    I'm mostly glad to see the implementation of HTML5 everywhere, but it has some problems.

    People thought that you could get rid of a lot of annoyances by increasing HTML5's capabilities to become more on par with Flash. Flash could be ditched. However, all it really means is that all the nuisances that were made in Flash (animated and noisy ads, commercials, persistent cookies, etc.) will now be made in HTML.

    Flash wasn't really the problem... it was just one of the vectors FOR the problem. Now, HTML5+Javascript will take Flash's place in the eyes of marketers and spammers everywhere.

    • This has absolutely 0 to do with HTML5 and works in any browser since (and including) Netscape Navigator.

      It does not however get around private browsing (at least not by itself, current flash implementations would allow it to do so however)

  • Please correct me if I am wrong on this; but it would seem that, in principle, it would be quite tractable to generate a 'local persistence profile' tracing the activity generated by loading a URL as a series of addition, deletion, and modification operations to the state that existed before the URL was loaded(in the same way the various browsers' dev tools allow you to trace the network activity and script execution associated with loading a URL). With that, the user would have broad power(limited largely

  • I just change the permissions on my cookies file to read only.

  • Invisibility is futile. We need fake cookies, or randomly collected cookies, so that the advertising value of a cookie falls, i.e. "information inflation". Sure, Vehix knows now that I was car shopping, but what if EVERYONE had a copy of the Vehix search on their Html? What if in addition to the car I was really searching for, my browser held a record of every other car I wasn't interested in? Why can't we just run a random program, searching for random words, in the background, loading up on Zombie co
    • Greasemonkey is a plug-in for Firefox that allows automatically executing your own scripts whenever you go to URLs that match a given pattern. You could easily write a script that looks at document.cookie and alters whatever cookies it sees. The only hard part would be deciding which cookies to overwrite, and how.
    • something like this? [cnet.com]

      if major browsers were forced to add this feature, the tiny background randomizing auto browser baking cookies at incomprehensible rates... I wonder what the demographics would be understood as by trendspotters... would anyone notice?
