Automatic tools has changed the world of penetration testing/ethical hacking, IT security researcher has been developed and currently developing different tools to make the test fast, reliable and easy.
Just consider the world without automatic tools, you can easily say that the hacking process is slow and time consuming.
We have discussed different tools before but in this article we summarise the best tools that are widely used in the world of hacking.
