Hello dear student,

There is no official exam conducted by government of India or any national level test to become a official hacker . While institutions conduct exams on their own. The Certified Ethical Hacker (CEH) is the broadest of all available certification options. The CEH exam is designed to test the cybersecurity professional's baseline knowledge of security threats, risks, and countermeasures through lectures and hands-on labs. I hope dear student this was helpful to you.

Thank you and best wishes
