The Indian Government has recently announced a bug bounty programme for tech savies to test the security of Aarogya Setu platform. To those who are still not interested yet, Government is willing to give upto 4 lakh to anyone who can help them find flaws in the app and suggest improvements for the same. This move has come into light after the government made the app platform open source. If you are interested you can find the Android source code on Github, while iOS codes are expected to be available in coming weeks.
