BUG BOUNTY TUTORIAL FIND HIDDEN INFORMATION FORM JAVASCRIPT | 2023 | BUG BOUNTY

Greetings, fellow cybersecurity enthusiasts! In this article, we'll be diving into the world of bug bounty hunting and exploring a specific skill that every bug hunter should have: the ability to find hidden information from JavaScript. By the end of this tutorial, you'll be well-equipped with the knowledge and tools needed to uncover those hidden gems and earn yourself some sweet bounties.
To get started, let's first define what JavaScript is. JavaScript is a programming language that is primarily used to make websites interactive. It runs on the client-side, meaning it is executed in the user's browser. JavaScript is often used to make websites more dynamic, and it is also frequently used by web developers to validate user inputs.
Now that we have a basic understanding of what JavaScript is, let's discuss why finding hidden information from JavaScript is important in bug bounty hunting. JavaScript can be used to hide sensitive information such as API keys, usernames, passwords, and even hidden pages or functionalities. This means that by being able to find this hidden information, we can potentially uncover vulnerabilities that may lead to a bounty payout.
So, how can we find hidden information from JavaScript? The first step is to identify the JavaScript files being used by the website. This can be done using browser developer tools, such as the Chrome DevTools. Once we've identified the JavaScript files, we can start analyzing the code to look for potential vulnerabilities.
One common vulnerability is the use of hard-coded API keys. Developers may use hard-coded API keys for convenience during development, but this can lead to serious security issues if the keys are left in the production code. By searching for keywords such as "API key" or "access key" within the JavaScript code, we may be able to uncover these hard-coded keys.
Another common vulnerability is the presence of hidden functionalities or pages. Developers may use JavaScript to hide certain functionalities or pages from users, but these hidden elements can often be found by analyzing the JavaScript code. By searching for keywords such as "hidden" or "display:none" within the code, we may be able to uncover these hidden elements.
In addition to these vulnerabilities, there are many other techniques that can be used to find hidden information from JavaScript. These include analyzing AJAX requests, searching for sensitive keywords, and analyzing the structure of the JavaScript code itself.
In conclusion, being able to find hidden information from JavaScript is an essential skill for any bug bounty hunter. By understanding the basics of JavaScript and analyzing the code for potential vulnerabilities, we can uncover hidden information that may lead to a bounty payout. Remember to always approach bug bounty hunting ethically and responsibly, and happy hunting!
