0x0ACE

Solutions for the 0x0ACE ARG (http://80.233.134.208/)

What is 0x0ACE?

0x0ACE is an ARG (augmented reality game) where the goal is to solve coding challenges.

Which challenges are currently available?

There are 3 challgenges available right now:

• #1
• #2
• #3

To access #2 and #3 you need to have generated a key by completing #1. #1 highlights a base64 string which is easy to decode with any online tool. #2 and #3, however, are refreshed every 5 seconds and must therefore be solved programmatically.

What are the steps to solving #2 a.k.a d34dc0d3?

To solve #2 you first need to send an HTTP GET request and parse the HTML response to get the values of the left and right limits of a set. You then need to HTTP POST the odd prime numbers between them, and a verification string.

What are the steps to solving #3 a.k.a 0x00000ACE?

To solve #3 you need to write your own interpreter for some bytecode with specifications on the page, and then HTTP POST the final register values back to the server.

When is the next challenge?

The next challenge will be released on the 30th of April.
