EVABS : An Open Source Android Application That Is Intentionally Vulnerable

EVABS is an open source Android application that is intentionally vulnerable so as to act as a learning platform for Android application security beginners.

The effort is to introduce beginners with very limited or zero knowledge to some of the major and commonly found real-world based Android application vulnerabilities in a story-based, interactive model.

EVABS follows a level-wise difficulty approach and in each level, the player learns a new concept. This project is still under progress and aims at incorporating as many levels as possible.
