Metadata Investigation : Inside Hacking Team

A really brilliant peace of research on the hacking team. All with the metadata that was leaked. A clear warning how much you can find out with meta data.
On July 5, 2015, one of the World’s biggest cyber weapon manufacturers and dealers – an Italian based company, Hacking Team, faced a leak of their internal email database. The twitter account of the company was compromised by an unknown individual who published an announcement of a data breach and provided links to over 400 gigabytes of data, internal emails, invoices, and source code.
In the next few days Wikileaks and Transparency Toolkit published a searchable database of Hacking Team’s emails revealing details of their operation, contacts and communication with government agencies, companies and individuals around the globe as well as the functionalities of their cyber surveillance weapons.
The concept behind data-mining and analysis operation performed by the government agencies around the world is that metadata can be analysed to reveal connections between people, and these links can generate significant investigative leads.
