Stranger Danger

In an ever-connected world, people all around the globe are freely surrendering their personal information and privacy over to the helms of the social media giants with unprecedented trust. We are quick to not only share our biographies and interests with complete strangers through these social media platforms, but in the process, have also managed to redefine the traditional definition of a friend. Our blind trust in social media platforms to protect our information have allowed us to forgo the age-old warning of ???stranger danger in our search for fame and popularity, in meeting new people, or in the never-ending quest of finding true love.

But what happens when this information falls in the hands of the wrong people? What if the social media platforms have not done as good of a job as they claim in protecting our personal information? In protecting us from criminals, stalkers, and others that mean to cause us harm?

In this presentation, we identify some flaws in one of the most popular social media platforms used globally today and demonstrate how an attacker can not only retrieve information about its users, but also track their location and movements around the globe. We also demonstrate through a study experiment how to extract information from people unknowingly and in the process, identify users that tend to use the platform for committing fraudulent acts like misappropriation, prostitution, and pedophilia.

But not everything has to end on a negative note. We conclude by demonstrating how law enforcement could possibly use this same data to their advantage to find criminals that may be active on the platform.
