Verizon Injects Unique IDs Into HTTP Traffic

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.

      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.

      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.

      just like you can NEVER trust a windows (or mac or even linux box) that was not setup by you, especially if its a corporate box that was given to you pre-installed.

      almost every company of mid-size or larger preinstalled MitM certs for their spying firewalls. they don't tell employees that, but netadmins and sysadmins pretty much all know this.

      I work at a large networking company and they didn't tell me WHAT they do or HOW they'd spy on me, but I found out via a friend (in germany) exactly what they are doing. in .de, you have to disclose to the employees a lot more than the US requires you to do, and he relayed the info to me about how our corp laptops come preinstalled with corp spyware. ability to active mic, camera, screen caps, all that bullshit in addition to traffic logging.

      I'm a network mgmt guy and when I was out interviewing for jobs (the last few years) almost all of them involved DPI and MitM attacks, even though they tried to explain it away as 'troubleshooting information' and 'for the users benefit'. quite bullshitty but they said it with a straight face, like they believe their own BS.

      you guys have to start realizing that corp america is all about privacy invasion; of customers and employees, alike. if you have a corp laptop, do NOT login to your home email systems and keep your work laptops entirely clean of anything personal and home related. yeah, even if you see the lock icon on the browser, it means nothing anymore, in a corp LAN.

      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.

      Well, that and use HTTPS everywhere possible, of course. But that requires that the sites you use allow people to do so (*AHEM* Slashdot, looking at you...)

      Oh, and don't use Verizon. That's the best way to hit them in the pocketbook, by far. I like the idea of sending the header even when you don't use Verizon though, as a general-purpose "fuck you!" to them.

      Since they're the ones adding the header, the client setting the header is futile. Verizon's version will clobber it.

      However, if you happen to run some intermediary servers that handle traffic once a backbone layer is crossed, then you can clobber their value.

    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.

When soldiering becomes less of a duty and more of a way to delay starting out your life of dismal poverty, you start making the wrong kind of army.

    I have come to the conclusion that anything the geek says about women, rape or the military needs to be fact-checked.

    A cash-strapped female soldier told a Fort Hood hearing board Tuesday about how a noncommissioned sexual assault prevention officer on base forced her into a prostitution ring so she could buy groceries for her child.

    The private testified against Sgt. 1st Class Gregory McQueen during a proceeding similar to a grand jury hearing. McQueen could face some 21 criminal charges if he is slapped with a military court-martial.

    ''Basically, it was having sex with higher ranking officers for money," the woman told the board.

    The private, who was 20 and struggling as a single mother of a 3-year-old child at the time of the alleged prostitution, was granted immunity in return for her testimony. She told the board how McQueen snapped pics of her naked to distribute to potential clients. The two also had sex so McQueen could see how she would ''act out'' with clients.

    McQueen, who has since been relieved from his sexual assault prevention duties, faces charges of pandering, conspiracy, adultery and sexual assault.

    Another female private claims McQueen sexually assaulted her when he tried to recruit her into the military sex ring.

    That woman told investigators that McQueen ''preys on young females who are in bad financial situations and that he keeps their pictures on his cell phone,'' the Austin American-Statesman reported in December.
