Verizon Injects Unique IDs Into HTTP Traffic 206

An anonymous reader writes: Verizon Wireless, the nation's largest wireless carrier, is now also a real-time data broker. According to a security researcher at Stanford, Big Red has been adding a unique identifier to web traffic. The purpose of the identifier is advertisement targeting, which is bad enough. But the design of the system also functions as a 'supercookie' for any website that a subscriber visits. "Any website can easily track a user, regardless of cookie blocking and other privacy protections. No relationship with Verizon is required. ...while Verizon offers privacy settings, they don’t prevent sending the X-UIDH header. All they do, seemingly, is prevent Verizon from selling information about a user." Just like they said they would.

          To be honest, I don't think this does anything. I think a VPN might be the only current way to avoid this, as your traffic in a VPN tunnel is theoretically not seen by the routers that pass it. I'm not sure if deep packet inspection tools could add the unique ID. I'm not a network engineer, so I don't know for sure. I do know that VPNs of today are rapidly becoming easier to circumvent by those who would do so.

          • I don't think you could modify packets that are in an ssl stream and not have ssl detect it and reject the 'broken' packets.

            https is mostly secure (other than MitM attacks on certs) and vpn's are also very secure.

            I have a vpn and while I use it mostly at home, there is an android client (even for my ancient 2.x android o/s) for the vpn provider I have and so I could get as complete privacy as possible on my phone, while doing inet things.

          And lose access to several websites. Slashdot, for example, redirects HTTPS hits to HTTP for non-subscribers because ad networks have been slow to implement HTTPS. And a lot of shared web hosts don't support HTTPS because their policies haven't been updated in the six months since the last major Server Name Indication-ignorant desktop web browser (IE on Windows XP) reached end of support in April. But HTTPS support is the second biggest reason I stopped going to TV Tropes in favor of All The Tropes (after licensing [slashdot.org]).

        Unacceptable. Verizon licensed the spectrum from citizens, and therefore has certain obligations.

        This is what should occur. Make use of any spectrum contingent upon a series of consumer friendly policies. Failure to comply requires turning the spectrum and any technology that uses it or assists in its use over to auction. Then establish a rule that prohibits anyone over a pay grade access to any industry that uses spectrum for a predetermined duration.

        If you set the concequesnces high enough than ideas like this get shot down in the board room.

      There has to be a way to prevent this

      As a sysadmin, you should know that it is easy and cheap to rent a VPS (Virtual Private Server). Then, run squid on the server, or do some fancy routing to send all your web traffic out via a VPN to your VPS. Since most VPS services offer a minimum of 1TB of monthy data, there should not be any excess data usage charges.

    • You still have the right.

      You just need to decide to not be a Verizon customer.

            The sites made up of custom code written before HTTPS was really all that common. It's such a mess that adding it now would require just as much work as just flat out rewriting the whole site. Last time they tried a site redesigned all the neck beards on here started shooting rocksalt at them and screaming "GET OFF MY LAW!!!"

            • There are tons of reports (just google them) of the server side cpu load being minimal to encrypt traffic. My guess is either the load balancing setup they have doesn't support SSL or their 3rd party ad network doesn't.

              In general, I think sites don't support https because of a) the extra cost of a cert, b) they don't care, c) the extra cost of a dedicated IP (SNI isn't supported on IE on XP). You can say "screw XP" all you want, but a good 20% still (of at least my traffic) comes from IE on XP.

Using an HTTP ad network from an HTTPS site would be blocked as mixed content, and HTTPS support among ad networks is very new.

If it works as he surmises, maybe we can overwhelm Verizon's ad exchange platform with meaningless data.

    • This plan. I like this plan! Put a random value in the header on every request. If you're not on Verizon, it'll look like you are (but as a different person every time). If you *are* on Verizon, you may just confuse the software that is adding those headers, or that is logging them. Poison their tracking data with meaningless garbage, and make it *cost* Verizon money to try and track us.

    Vodafone injects the X-VF-ACR header: 'Vodafone Anonymous Customer Recognition'. It is unclear what this header exactly does; all headers that have been seen start with the string "204004DYNMVFNLACR", followed by 16 X's, and are followed by a BASE64-encoded 256-byte cyphertext, which we were unable to decrypt. It has been suggested that this string might contain the SIM-card identifier (IMSI) or other personal information, as was found in a research conducted by Mulliner in 2010 [14]. Vodafone did not respond to requests of explaining this header. Nevertheless, the presence of this header, certainly identifies customers of Vodafone as being customers of Vodafone.
