BYOD is not a new concept. From contractor laptops to an employee’s game console in the break room, a compromised device in the corporate environment can lead to all sorts of bad things. In this talk we will look at the unique threats that BYOD for mobile devices brings to the table. The most security conscious corporations are deploying the latest devices and policies to stop attackers from breaching the perimeter and if they do to stop data exfiltration. We will discuss how mobile devices on a corporate network and/or handling company data undermines these efforts. We will look at multiple mobile platforms gathering sensitive information, attacking other devices such as other mobile devices, servers, and workstations, and using out of band communication to perform data exfiltration and communicate with internal devices. Multiple live demo scenarios will be shown and some useful code for pentesters will be released.
