Secure Agent

 When I opened the secure agent challenge there is something like an error message on the page that tells me that the user agent is not correct.

Now from my previous CTF experience, I know what a user agent is, but let me tell you anyway, A user agent is any software that retrieves and presents Web content for end-users or is implemented using Web technologies. User agents include Web browsers, media players, and plug-ins that help in retrieving, rendering, and interacting with Web content.

In simple words, a user agent is the name of the software that you are using while loading a webpage.

You can learn a lot more about user agents on google.

But the thing here is we have to change that user agent to "secure_user_agent" to solve this challenge.

Now, how to change the user agent, Well I used a chrome extension to change the user agent, and it works well for me. 

Chrome Extension - https://chrome.google.com/webstore/detail/user-agent-switcher-and-m/bhchdcejhohfmigjafbampogmaanbfkg/related

After installing the extension, just open it and change the default user agent to secure_user_agent.

Now that we have changed the user agent click apply to the active window and refresh the challenge page. 

And Boom you solved the challenge.
