Remember That Undeletable Super Cookie Verizon Claimed Wouldn't Be Abused? Yeah, Well, Funny Story...

from the your-privacy-preferences-now-mean-absolutely-nothing dept

A few months ago, we noted how Verizon and AT&T were at the bleeding edge of the use of new "stealth" supercookies that can track a subscriber's web activity and location, and can't be disabled via browser settings. Despite having been doing this for two years, security researchers only just noticed that Verizon was actively modifying its wireless users' traffic to embed a unique identifier traffic header, or X-UIDH. This identifier effectively broadcasts user details to any website they visit, and the opt-out settings for the technology only stopped users from receiving customized ads -- not the traffic modification and tracking.

AT&T responded to the fracas by claiming it was only conducting a trial, one AT&T has since claimed to have terminated. Verizon responded by insisting that the unique identifier was rotated on a weekly basis (something researchers found wasn't true) and that the data was perfectly anonymous (though as we've long noted anonymous data sets are never really anonymous). While security researchers noted that third-party websites could use this identifier to build profiles without their consent, Verizon's website insisted that "it is unlikely that sites and ad entities will attempt to build customer profiles" using these identifiers.

As such, you'll surely be shocked to learn that sites and ad entities are building customer profiles using these identifiers.

Not only that, they're using the system to resurrect deleted tracking cookies and share them with advertising partners, making consumer opt-out preferences moot. According to security researcher Jonathan Mayer (and tested and confirmed by ProPublica), an online advertising clearinghouse by the name of Turn has been using Verizon's modifications when auctioning ad placement to websites like Google, Facebook and Yahoo for some time. When asked, Verizon pretends this is news to the company:
"When asked about Turn's use of the Verizon number to respawn tracking cookies, a Verizon spokeswoman said, "We're reviewing the information you shared and will evaluate and take appropriate measures to address." Turn privacy officer Ochoa said that his company had conversations with Verizon about Turn's use of the Verizon tracking number and said "they were quite satisfied."
Like Verizon's implementation of the program, Turn lets users opt out of receiving targeted ads, but users have no way of really opting out of being tracked or having their packets manipulated without prior consent. As the EFF notes, your only option is to use a VPN for all your traffic, or to use a browser add-on like AdBlock, which doesn't fully address the issues with the use of a UIDH header. Amusingly, Turn tries to claim to ProPublica that it's actually using Verizon's UIDH to respect user behavioral ad opt out preferences, but the website found that repeatedly wasn't working:
"Initially, Turn officials also told ProPublica that its zombie cookie had a benefit for users: They said they were using the Verizon number to keep track of people who installed the Turn opt-out cookie, so that if they mistakenly deleted it, Turn could continue to honor their decisions to opt out. But when ProPublica tested that claim on the industry's opt-out system, we found that it did not show Verizon users as opted out. Turn subsequently contacted us to say it had fixed what it said was a glitch, but our tests did not show it had been fixed."
Even if Turn's being honest, there are plenty of companies that aren't going to bother being ethical. Verizon, which in 2008 insisted that consumer privacy protections weren't necessary because public shame would keep them honest, pretty clearly isn't interested in stopping the practice without legal or regulatory intervention. So yeah, again, we've got a new type of supercookie that tracks everything you do, can't be opted out of, and is turning consumer privacy completely on its ear, but there's absolutely nothing here you need to worry your pretty little head about.

A good test is how the perpetrator reacts to the inverse: if they have no plans to abuse something, they won't mind removing the parts that can be abused. If they object to that or back-peddle, you can bet they've got plans to abuse it to within an inch of it's life and they don't want to admit to them.

    I can save them a lot of time and money in conducting their review: the only possible appropriate measure available is to stop injecting these tracking numbers.

    Like Verizon's implementation of the program, Turn lets users opt out of receiving targeted ads


    This sort of response from companies that track users makes me angrier at those companies than if they just said "suck it, you can't opt out". My objection to the tracking is not the advertising. It's the tracking itself.

What the web-server does with it is to talk to "turn" etc and build a profile on you (even if you don't get served any adverts). Any notion that the ad networks don't get back any info is ludicrous. There would definitely be server-side tracking going on. And I'm betting the NSA is loving this.

    Are you a child molester?

    I have to think of that case where some mother furiously reacted to some supermarket sending her 16-year old daughter diaper and baby clothes advertisements only to figure out afterwards that the browsing habits analysis leading to that targeted advertising had been pretty much on-spot.

    N O W, that makes me suspect that the "does not want to be spied upon -> child molester and/or terrorist" conclusion that NSA and its bosses come up in every political argument with is a lot less sophisticated than what advertising companies can come up with, never mind the gigantic data sets they are working with.

    So it would seem just sensible if the task of proposing stings and FBI operations was taken off the NSA and given to Walmart and Toys'r'us. That should cut costs considerably while improving accuracy to a degree where some suspects might possibly even be arrested before they complete their attack: something that all the spying somehow so far failed to accomplish.

    Most of the time, I refuse to stay at a site that requires NoScript to temporarily allow to see the contents. If that is required, you can bet it is a datamining point. Likewise anything I can do to prevent datamining and ad presentation is blocked. I also run it through a VPN. I doubt all that will prevent datamining but it will slow a lot of it down.

    I am not asked if I want to opt out. Giving a cookie to opt out is meaningless as soon as you clear the cookies for those that won't pay attention to your desires to not be datamined. Most folks don't realize you can whitelist cookies till it's too late and it's gone.

    I'm totally fed up with all this spying, datamining, and trying to force ads on you.

    The firewall I use on my Android phone (DroidWall) makes this easy to enforce, as you can easily set it up so that specific applications are blocked from using the cell network but can use WiFi.

    What this does, is to screw up utterly any chance the advertisers have of targetting actual customers as everyone appears to have completely random and arbitrary tastes and everyone they ever meet appears to have visited X and Y sites....

    There are android, PC and Mac apps to do just this thing.

    Re: Re:

    I don't see how, if enough people started doing it (e.g. via a browser plug-in).

    Maybe you misunderstood? what I had in mind was something like this:

    If the original insert is (simplified for clarity)
    /TAG id=1234/

    ... a few lines, with random ids, could be added beforehand (e.g.):

    /TAG id=4321/
    /TAG id=3412/
    /TAG id=1324/
    /TAG id=3142/
    ....

    You get the picture.

    Ha, if the plug-in could be pooled to use actual ids, it would confuse the collection no end. (I realise no-one would like to give that away, of course.)

    Biggest issue I can see is not being able to control the placement, as the actual tracking id would be either first of last. Don't know of-hand of a work-round for this.

    Anyway, just a thought experiment, nothing more.
    It goes without saying that this behaviour should be abandoned forthright!

If X-UIDH tracking was implemented correctly, this checking is already taking place.

    Non-competition clauses between American ISP's make changing service an exercise in 'how much more do I want to pay for worse service', if an alternative option exists at all.

    A few years back, I moved into an apartment complex in an area I new supplied ATT broadband. I know because I asked the businesses 300 yards from my front door. So when I went to sign up for ATT broadband, they told me it wasn't available in my area. I explained that I knew that was untrue and asked why I was being offered restricted service.

    I was told that because my area wasn't considered profitable enough (read: not upper-middle class) ATT could only offer me DSL service.

    The funny part is, I moved to what appeared to be the end of the same apartment complex where the higher class people had been gentrified, and I got ATT broadband no problem. This was in the same apartment complex.

    Does this affect Verizon FiOS as well or just Verizon Wireless?

    VPN

    This is the sole reason I shelled out the money to use SurfEasy. Research what's available for VPN services and use it. If they want to use my information without my permission, then these a-holes are going to work for it.

    Jonathan Mayer played with it a bit. His observations are here, and show how turn responds to fake X-UIDH: and Cookie: (self-generated uid) headers. It answered a couple of questions for me, but raised several new ones.

    Nice little informative article. Now when people ask why I would switch to T-Mobile even though Verizon has better coverage I can just link them here.

    FCC, where are you?

    If the FCC wants to regulate something, this would be worthy of that. They should stop this in its tracks. Could a hacker get ahold of this and figure a way to use this against us? Could businesses use it to discriminate? When people go on the internet they quite often don't want people stalking them wherever they go. A little bit of privacy is nice from time to time.

    Re:

    Root your phone, get a copy of the f-droid repo manager and install ad-away: it edits the hosts file to send all ad traffic back to the local loop. Good stuff. Unfortunately (or not, your call) it doesn't permit you to whitelist sites and services you care to support.

    Re: Re:

    Correction: it does allow you to whitelist servers if you care to. It also allows you to blacklist whatever you want as well: you can directly edit the hosts file however you like.

    according to the website you suggest, my Sprint account isn't tracked.

    I just tested it with T-Mobile and it said "Congratulations, you're not being tracked by your carrier" so I'm stoked about that.

    Re: Re: Re: Better research...

    Non-competition clauses between American ISP's make changing service an exercise in 'how much more do I want to pay for worse service', if an alternative option exists at all.

    True, but this is about cell phones, not home broadband.
