Web Application Security Blog | Tracking performed by social networks Web Application Security Blog | Tracking performed by social networks In this blog post I analyze methods of user tracking which are performed by popular social network websites such as Facebook , Twitter , Xing , and recently Google+ . Each of these social networks have buttons (called Like , Tweet , Visitors , and +1 buttons) which are installed on numerous websites. I try to put some light on the actions performed by those buttons and how they track users around the web, even when they don't click those buttons.
Facebook Struggles to Explain Its Web-Tracking Practices Facebook Struggles to Explain Its Web-Tracking Practices Facebook’s business is built on trust, but that trust has been shaken over the past few weeks by criticism and speculation regarding how it uses browser cookies to get data about users. A lack of thorough documentation explaining what each of its cookies does has led some observers to assume that the company is tracking offsite browsing behavior in order to target ads. Facebook needs to provide explanations for both the average user and privacy researchers about how exactly its cookies work in order to prevent these press flare-ups from giving users a negative impression and bringing on regulatory scrutiny from governments. Some bloggers claim cookies left by Facebook and third-party sites that integrate its social plugins indicate that the company is tracking users’ web browsing behavior, then using that data to target ads in a way that violates user privacy.

Cookies espions : Facebook réfute, avant pourtant de corriger Cookies espions : Facebook réfute, avant pourtant de corriger Voilà encore un épisode qui ne devrait guère profiter à l’image du réseau social. Quelques jours plus tôt, un hacker australien, Nik Cubrilovic, révélait que Facebook pouvait continuer à collecter des données sur la navigation de ses utilisateurs après que ceux-ci se soient déconnectés. Par le biais d’un de ses ingénieurs, Arturo Bejar, sans donc emprunter le canal officiel, la firme américaine avait réfuté toute indiscrétion, niant tout traçage de l’activité des internautes.
With ‘frictionless sharing,’ Facebook and news orgs push boundaries of online privacy With ‘frictionless sharing,’ Facebook and news orgs push boundaries of online privacy Facebook again may have gone too far in its quest to make privacy obsolete, and this time some news organizations could get burned by going along with it. Facebook spent years making it easier for us to share by building its network and placing “Like” buttons across the Web. Its latest idea goes much further, turning sharing into a thoughtless process in which everything we read, watch or listen to is shared with our friends automatically. Encouraging sharing is great. Making sharing easier is even better. But this is much more than that.

Very rarely is there a Gargamoyle sitting in a tower plotting the downfall of the smurfs. Most times it's just someone with the best of intentions. In this case your argument is that you just want the information so as to provide people what they want.
Update: Facebook fixes cookie behavior after logging out. Over the weekend, self-proclaimed hacker Nik Cubrilovic accused Facebook of tracking its users even if they log out of the social network. The company has denied the claims and has offered an explanation as to why its cookies behave the way they do. For reference, here's what I wrote based on Cubrilovic's findings: After running a series of tests analyzing the HTTP headers on requests sent by browsers to facebook.com, he discovered that Facebook alters its tracking cookies the moment you log out, instead of deleting them.

Facebook Tracks and Traces Everyone: Like This! by Arnold Roosendaal Facebook Tracks and Traces Everyone: Like This! by Arnold Roosendaal TNO Information and Communication Technology in DelftNovember 30, 2010 Tilburg Law School Legal Studies Research Paper Series No. 03/2011 Abstract: Numerous websites have implemented the Facebook Like button to let Facebook members share their interests, therewith promoting websites or news items. It is, thus, an important business tool for content providers. However, this article shows that the tool is also used to place cookies on the user’s computer, regardless whether a user actually uses the button when visiting a website.
