The Natas1 challenge can be solved in two ways, examining the webpage using a browser’s developer tools or by using a web proxy tool such as Burp Suite.
Using the first method, users can examine the HTML code and find a password for the next level in a comment within the code.
The second method involves using a web proxy tool to intercept and analyse traffic to and from the challenge URL.
This reveals the password in the response data sent from the server to the client.
The significance of this challenge is to highlight the risk of leaving confidential information in versioned code or in client-side code that is intended to block certain functionality.
Even when developers try to block certain browser functionality, full visibility of frontend code is still possible using proxy tools.
