Data Collection: 2# Social Media Buttons

Nowadays almost every website uses social media buttons from Facebook, Google+ and Twitter. However, when visiting any of these sites these buttons send information back to Facebook & Co. Even if you are not logged in into one of these networks, they collect the address of the web page you are visiting and some other meta data which can identify you. Clicking on the social media button is not required. This way these networks are able to track which websites users are visiting and are able to build fairly complete browser histories of their users. Creepy, I know.

To prevent this unwanted data leakage we choose an alternate approach. The concept is fairly easy. Per default only a gray mockup image of a like-button is embedded. Only if a user clicks this button the real like-button is loaded and information is sent to the social network. With a second click the user can then like the webpage (or tweet it etc.). Unfortunately some of our competitors don’t know this and expose their visitors to third party data collection.

Cell phone wiretapping roundup

Matt Blaze wrote a nice roundup about cell phone wiretapping and tracking. As some of these techniques are already well known by interested individuals, I just want to add another method which at least seems imaginable.

As modern smart phones are basically personal computers, it shouldn’t be that difficult for some agencies to exploit them in order to place some nice malware on the phone. So it’s perfectly imaginable to leave the cellular radio running and registering with the cell network even after the off button has been pushed and the phone appears to be off. For that reason don’t be surprised when you discover you’ve been tracked and spied on while carrying a power-off cell phone with a battery in it.
