NSA Uses Google Cookies To Pinpoint Targets For Hacking

Hugh Pickens DOT Com writes "For years, privacy advocates have raised concerns about the use of commercial tracking tools to identify and target consumers with advertisements. The online ad industry has said its practices are innocuous and benefit consumers by serving them ads that are more likely to be of interest to them. Now the Washington Post reports that the NSA secretly piggybacks on the tools that enable Internet advertisers to track consumers, using 'cookies' and location data to pinpoint targets for government hacking and to bolster surveillance. The agency uses a part of a Google-specific tracking mechanism known as the 'PREF' cookie to single out an individual's communications among the sea of Internet data in order to send out software that can hack that person's computer. 'On a macro level, "we need to track everyone everywhere for advertising" translates into "the government being able to track everyone everywhere,"' says Chris Hoofnagle. 'It's hard to avoid.' Documents reviewed by the Post indicate cookie information is among the data NSA can obtain with a Foreign Intelligence Surveillance Act order. Google declined to comment for the article, but chief executive Larry Page joined the leaders of other technology companies earlier this week in calling for an end to bulk collection of user data and for new limits on court-approved surveillance requests."

      I'm not so sure about that. I am afraid this is one of those deals where the compromise (require the user be presented with an opt-out) turns out to be worse than either of the proposed "pure" alternatives (do not regulate tracking at all, vs disallow all tracking, period).

      Because what happens is a site says: either allow my cookies or I will not, or not fully, serve you. And because the average user is basically an idiot -- as is true for any large group of people, and in many instances of course it includes myself -- they go for it.

      Tracking not reduced for all a but a tiny minority of paranoids and actual baddies, and the ad companies can now say they do it with user's consent.

      This PREF cookie is an especially nasty piece of work, seeing how it rides on the very Safe Browsing system that Google "generously" facilitates to protect against online malware. Check the link in TFS.

      The most sensible solution is to allow only sessions cookies. I know everyone loves their "keep me logged in button" but simple solution is to have browsers silently convert all cookie requests to session cookies no matter what the server or script asks for.

      This should do be the default, as it breaks very few sites and existing web applications other than you have to logon every time. Users should have to manually go white list domains that are allowed persistent storage.

      Browsers need to stop providing useragents, they need to start sending strings like
      "traditional HTML 5.0 ready browser" or "touchscreen HTML 5.0 browser" instead.

      The default behavior should be to only send a referer header when the request is to a page on the same domain as the one already being displayed.

      As much as I hate to advocate it because its a waste of everyone's network resources, the same approach needs to be applied to document caching. There are to many possibilities for script based timing analysis attacks and server side request analysis that will enable tracking with the cache enabled.

      Implement those changes and you will an WWW that still mostly works without alot of changes to existing sites but is decidedly less trackable.

    Personally, the collection of privacy relevant information by private companies like Google is way more scary than what a government fools around with.

    And don't come, it's voluntary. It's anything but, considering how many sites include elements from Google/Facebook/... (e.g. ads or like buttons), and they DO track you even if you are not a registered user. And the end user tools to customize browser behavior (to suppress unwanted elements of a webpage) are mostly non-available on mobile platforms

    Worse, as is the "fundamental law" of privacy & data collection, any data collected will be abused. (Classical example, when the truck toll system in Germany was introduced, it was only allowed by the data privacy commissioner because it's absolutely illegal to use the data for anything but tolling. Couple years later, new government, and immediately "let's use the toll data for law enforcement" is a nice idea in the back rooms.)

    So Google might be collecting "anonymous" data about person X, not knowing who X is, but that does not mean that the identity of X cannot be revealed later on, or be known by a third party.

    Worse, anonymizing data (removing the parts that identify the user and potentially replacing them by a random id) is way harder, e.g. an interested adversary can usually reconstruct the identities, sometimes even trivially.
