In HTML source code:<span><script type="text/javascript" src="main.js"></span><span></script></span>In main.js:<span>	if (password == "53cure" && username=="@nokh@") {	    alert("Awesome!");             window.open("secureflag.html");	} else { 	    alert("Oh swap!You are close. Why cant you try again?"); 	}As it says, if I give @nokh@ as username, and 53cure as password, it redirects to a jpeg file, and it has flag near file's end, as binary.</span>
