Inside Hacking Team

We often hear about metadata – that is, data about data. Apart from the content of your communications, metadata can reveal what we are doing, with whom, when and where. This visualisation looks at the leaked emails of one organization and shows the amount of information that can be gleaned just by looking at metadata generated by sending and receiving emails. Even without the content of communications, we can get a detailed picture of the company, its dealings, social networks and internal politics. This technique can be applied to all of us – the more metadata our email provider has, the clearer their picture of us becomes.
