Phorm Phudged

virgin-mediaThree of the UK’s biggest internet service providers – Virgin Media, BT and TalkTalk – allegedly sell your private web browsing history to an advertising broker using a system called Phorm. The contents of every web page you visit, apparently, gets harvested by Phorm in realtime as you click, and this is used to create a personal profile, which can then be used to send you ‘targeted advertising’. Bad phorm indeed and the equivalent of NebuAd on ISPs elsewhere.

I don’t like the idea that your ISP has some kind of built in system to track all your web browsing and is assimilating a profile of you on that basis and then using that to target you with ads and redirect you to pages you otherwise wouldn’t see.

Now, you could probably get around this problem by using HotSpot Shield, as it creates an encrypted virtual private network connection between you and the internet (great for surfing privately on public wifi systems). However, Hotspot will effectively slow down your connection to some degree and running it means certain email and FTP clients will not work their 100% best. An alternative that works within your browser would be much better.

So, thanks once again to ghacks for alerting us to Firephorm a Phorm-burning Firefox extension (obviously doesn’t work with Google Chrome).

Ghacks’ Martin explains that Firephorm allows you to send broken cookies to the Phorm tracking system, so rendering its analysis useless. “Firephorm provides the option to forge the master cookie and the tracking cookies to either poison the system by using random cookies, using an opt-out cookie or from an UID list specified by the user,” Martin explains.

    The preventative measures are good, but it’s not too late to stop this ever happening.

    This spying technology has already been stopped in the USA, and is on the ropes in the UK.

    From what I’ve read Phorm is not yet used at any of the 3 ISPs. BT are trialling it – which is a whole other issue entirely – but no one is actually using it full time (or so we are told…).

    If they’re trialling it…then some of their users are already being monitored, surely?

  • Dave Pimlott // Oct 30, 2008 at 3:13 pm

    The trials were/are of fixed length so yes monitoring has happened and is (as of yesterday) currently happening to thousands of customers ( http://www.theregister.co.uk/2008/09/29/bt_phorm_trial_go/ with further links for more info on phorm) who will have the opportunity to opt-in or -out.
    FWIW I’ve signed the petition as well as I also vehemently oppose such technology being used.

    UK ISPs TalkTalk and British Telecom have abandoned their relationship with Phorm.
