Description:
Harry’s Invisibility Cloak does a fantastic job hiding him from Voldemort. Is it hiding anything else?
This challenge simply involved using your browser tools to inspect the source. In the html you would notice a <span>
tag with inline styling making it invisble.
<span style="color: transparent;cursor: none; text-shadow: 0 0 5px rgba(0,0,0,0.09);text-decoration: line-through;">kossCTF{always_inspect_the_source}</span>
A simpler approach to these kind of challenges is to simply do Control + A
(select all) on the web page. This highlights everything, including “invisible” elements.
