  The best way to train people about security is through Cyber Ranges, i.e.,
the virtual platform used by cyber-security experts to learn new skills and
attack vectors. In order to realize such virtual scenarios, container-based
virtualization is commonly adopted, as it provides several benefits in terms of
performance, resource usage, and portability. Unfortunately, the current
generation of Cyber Ranges does not consider mobile devices, which nowadays are
ubiquitous in our daily lives. Such devices do often represent the very first
entry point for hackers into target networks. It is thus important to make
available tools allowing to emulate mobile devices in a safe environment
without incurring the risk of causing any damage in the real world. This work
aims to propose Dockerized Android, i.e., a framework that addresses the
problem of realizing vulnerable environments for mobile devices in the next
generation of Cyber Ranges. We show the platform's design and implementation
and show how it is possible to use the implemented features to realize complex
virtual mobile kill-chains scenarios.
