Google already rewards people for finding big security vulnerabilities in its services. Instead of suing or taking legal action against people who try to help like some other companies have done, Google rewards those people for assisting in making its services safer for everyone. Now Google will be doing the same for Android!
Security Rewards for Android will reward those who find vulnerabilities in the current Google Play Store devices, which are the Nexus 6 and Nexus 9 (meaning the bugs will have to be in AOSP). Each step required to fix it will pay out. If you actually make patches, there’s extra reward for you. And finally, there will be rewards for researchers that can work around Android’s security features.
If you’re up for the challenge, take a look at the source link for more info! Maybe you’ll make some money and do all Android users good.
