Bug hunting, a very small word.
But its meaning and importance are two opposite.
You all are definitely unaware of hacking.
The power to destroy a person's life, like a hacker,
Such a whole race can only be exploited through this hacking.
A branch of hacking is bug hunting.
I'll make it a little easier.
I hope you are familiar with all these things.
If you are familiar, then you will know that all these things are possible by coding thousands of lines.
In fact, everything is coded.
But now we are talking about vulnerability.
And how will the vulnerability or bug come in this code?
I will show you a little bit.
This is a website of Google Play Store.
We don't think there are thousands of lines behind this website.
If we click on the right side of the website, we can see that all the codes are shown here.
Now, the code is being done by humans, right?
Machine is not coding anymore.
The fact that humans are coding so many lines,
humans can only make mistakes.
That means, humans make some mistakes in the code.
Developers make some mistakes in the code.
And because of that mistake,
that website becomes hackable or vulnerable.
That means...
There is a bug
I hope I was able to explain to you
If you have any problem understanding this way
I will try to explain to you in a different way
Suppose you are a developer
And you have to give a task
Create a website like this
Or a simple website like I am showing
payment.testfire.net
To create a website like this
This is where you will find the sign in, sign up page and search option.
Now, you create a website, keep in mind that the users who will come to your website,
they can sign in, sign up or do some search.
You can search by using this search bar.
The thousands of users who will come to your website,
They don't even know what to put in the input field of your signup page or signin page.
Now, you have created a search bar.
The job of the search bar is to find and display various facts from the website.
But, if the user has changed the functionality of the search bar by injecting a code,
For example, I have given a search here,
Now, we are going to show the back.
But I am a malicious user, so I wrote some code here.
I wrote the script and then I gave it.
You can see what happened.
I changed the whole work of the search bar here through a code.
