Apple introduced “Sign in with Apple” with iOS 13 along with other major features like “Deep Fusion“, a powerful photo editor, and the popular “Dark Mode“. Now, “Sign in with Apple” was more of a privacy-focused feature, unlike the mentioned ones. However, Bhavuk Jain, an Indian developer with a BSc. in Electronics and Communication degree found that there was a Zero-Day vulnerability in the “Sign in with Apple” account authentication system. He reported this to Apple and the company rewarded him heavily for the deed.
Now, after spotting this vulnerability, Jain reported this to Apple via the company’s Security Bounty Programme. And Apple, in turn, awarded the 27-year-old developer $100,000 (~Rs 75,57,350).
