Targeted cyber attacks sometimes imply to investigate and mimic the people who work in a physical environment, who their clients are, what are their most common suppliers or services and more. Knowing about them and about your team (including yourself) can lead to a successful phishing or physical social engineering attack. Hardware hacking is usually related to this, as most of the gadgets need to be used physically close to the target. In this talk I'd like to explain how to investigate, profile a character, disguise the devices I build and use all public resources to make other people think I am someone that I'm not.
