I'm looking for a list of exercises or distributions to practice penetration testing on mobile environments. There are plenty of existing things like the environments found at pentesterlab.com and things like Mutillidae, hackthissite.org etc. However all these are for desktop/server environments.
There seems to be quite a lack of mobile-space environments to test with (something that supports both android and iOS would be ideal).
If there are walkthrough guides/solutions for such tutorials that would also be great.
Hope someone can help!
