You can participate with the CTF by submitting your exploit or an link to an article that you created about it. The most inventive exploits and best articles will be listed and small prices will be awarded.
The reason for this is, is that we will publish a series of articles which are for free and are based on Arvm7 and don't require Mobile Hacking Lab platform. This will allow you to setup your local lab environment and start building your first exploit without any costs.
Further more, Armv7 is much easier to emulate on x86_64 machines, giving more people access to Arm Exploit Development making it more realistic mobile exploitation experience.
Although the CTF is Armv7 based, all the trainings on the Mobile Hacking Lab platform are based on Arm64.
To setup your local lab environment make sure to emulate an Android 7.1.1. Pixel 3a API 25 Device.
