Back The Hawks

Challenge Description

We are Back the Hawks! We're a non-profit that seeks to protect hawks across the world. We have a vibrant community of Backers who are all passionate about Backing the Hawks! We'd love for you to join us... if you can figure out how to get an access code.

NOTE - any resemblence to other companies, non-profits, services, login portal challenges, and/or the like, living or dead, is completely coincidental.

Solution

• Visting the Register page, asks for an Access Code
• Checking the Hint on the page
• Checking the javascript file backTheHawksInviteCodes.min.js

function makeInviteCode() {
    var o = "! edoc/etivni/skwah/eht/kcab/ ot tseuqer TSOP a ekaM !skwaH eht gnikcaB htiw nwod er'uoy erus ekam ot tnaw YLLAER ,yllaer eW";

    var d = o.split('').reverse().join('');

    console.log(d);
}

• Reverse the string of characters
• It says Make a POST request to /back/the/hawks/invite/code
• We get a message after making a POST request to that endpoint

• Decrypting the message using Shift Cipher with shift of 23, we get : WE_OUT_HERE_BACKIN_THE_HAWKS_2023

• Enter the access code on the Register page and we get the flag
