Vulnerability Databases And Resources
Vulnerability Databases are the first place to start your day as a security professional. Any new vulnerability detection is generally available through the public vulnerability databases. These databases are a big source of information for hackers to be able to understand and exploit/avoid/fix the vulnerability.

Summary
I have tried to compile some of these resources for my own reference for the journey of learning I am going to start. I am not even at a beginner level of becoming hacker but the knowledge of this field really fascinates me and keeps me motivated for learning more and more. I hope will be able to become successful in this.
A lot of people use their knowledge skills for breaking stuff and stealing. I personally think that doing harm to someone is a weak choice and will not have a good ending. I would recommend not to use your skills for any un-ethical endeavor. A single misuse of your skill may jeopardize your career since most companies do a strict third party background check before they hire a ethical hacker or a security personal.
There are dozens of companies looking for ethical hackers and security professionals. There are really good number of opportunities in this area and its really niche compensation segment. You will be easily able to get a decent job without even acquiring all the expert level skills to become a pro hacker.
