Points: 65 Description:
Sometimes, you gotta be quick.
The link that the description provides takes you back to the problems page, meaning that the flag must be hidden on that page. As with any web challenge, you should open up your browser's developer's tools (we used Chrome). Chrome's developer tools has a host of useful tools, including a Javascript console and a resource viewer.
The problem title implies that you have a limited amount of time to view the flag, which necessitates constant refreshing. Eventually, you might stumble upon a suspiciously named cookie named QuicklyNow
, which has a value of 7730775f796f755f6172655f737065656479
.
This hexadecimal string can be converted to ASCII to get the flag.
