Quest:
Password
Immediately, we are prompted to enter the password. Let's just do a quick "view-source" and we can quickly spot the following Javascript.
<body onLoad="password()" class="usual" link="#FF9900" bgcolor="#D0D0D0"><script type="text/javascript"> function password () { var d1, d2, d3, d4, d5, input; d1=window.document.bgColor; d2=window.document.linkColor; d3=d1.substring (1,5)+d2.substring (1,3); d4=d3.toUpperCase (); input=prompt("Password:",""); if (input!=d3 && input!=d4) { alert("Are you crazy? Thats so easy!"); window.location.href="/hackchallenge.php"; } else { window.location.href=d3+".php"; } } </script>
As we can see, we are required to have d3 or d4 as password.
Well, the easy way to solve this challenge is to either manually write out the substring or save the entire page and add the following line of code

alert(d4);
right before
input=prompt("Password:","");
We will see an alert with D0D0FF and that is our answer for this challenge.
That's pretty easy for everyone to understand. :D
