We recently announced LabyREnth, the 2nd Annual Palo Alto Networks Capture the Flag (CTF) Challenge, will go live on June 9, 2017. Like last year, the LabyREnth countdown page included a little teaser… Were you able to find it? If not, don’t worry. We’ve added a link to the CTF information on the countdown page because we want to make sure everybody has a chance to see the information. We’ll also show you how to solve the teaser in case you still want to try it out.
We’re giving away some amazing prizes this year! We’ve increased the amounts of all the cash prizes and the first person to solve all the challenge tracks will win $10,000. We hope this will motivate lots of people in the security community to play, learn, and have fun.

In order to solve the teaser challenge, start out by navigating to the main labyrenth.com page.
If we pull up the developer tools for the page we can see that clicking anywhere in the body of the page will redirect us to a 404 page. That is very unusual, so let’s follow that thread and see where our curiosity takes us.

Figure 4 404 Page with Hidden Input
Figure 7 Decoding the correct resource
We can put G3t$chW1fty into the hidden text box on the 404 page or go directly to the resource we decoded to get the fake web shell. We can interact with the fake shell by typing help for the available commands.
The team has lots of surprises in store for the CTF that we think you will have fun with. Good luck and we hope to see you in the LabyREnth on June 9!
