Advent of CTF – Day 1 Writeup
This is Day 1 Challenge of Advent of CTF challenges! You can find the previous challenge here: Advent of CTF – Day 0 Writeup. This challenge describes itself as a pretty easy. Which means that we shouldn’t think too hard about it in order to solve this challenge.
Opening the challenge URL gives us the following page
We are greeted with a short message that says that Santa is a huge fan of Star Wars, the more you know!
After filling in a couple test password, the only strange thing we can see is that the password is handled through a GET parameter in the URL bar.
Let’s check the page source to see if that has some more information for us.
Upon checking the page source we see a strange self-aware HTML comment
<!-- This is an odd encoded thing right? YWR2ZW50X29mX2N0Zl9pc19oZXJl -->
If we decode this base64 string we get the password of Santa: advent_of_ctf_is_here! This results in obtaining the following flag: NOVI{L3T_7H3_M0NTH_0F_FUN_START}
The next challenge: Advent of CTF – Day 2
