Hacker101: A little something to get you started Write-up

Today I’ve registered my account on HackerOne.com. And in this post, I want to share with you my first write-up from one of the CTF challenges from Hacker101. Hacker101 is a free class for web security. Whether you’re a programmer with an interest in bug bounties or a seasoned security professional. In my case, I’m new to the Infosec world and I want to learn myself into the world of Cyber Security.

After I started this challenge, I landed on this webpage.

Welcome message

As I check the source code of this webpage, I see that the background is an image.

<!doctype html>
<html>
	<head>
		<style>
			body {
				background-image: url("background.png");
			}
		</style>
	</head>
	<body>
		<p>Welcome to level 0.  Enjoy your stay.</p>
	</body>
</html>

I placed the image path into the web URL: http://35.190.155.168/e2c36f1f4d/background.png and I have found the flag.

This was a really, really and really easy CTF challenge. I will post more write-ups from Hacker101. After each challenge, the level of difficulty becomes more and more difficult. Looking forward to it!

Thanks for reading!
