Welcome to the first post
So in this post I will share a challenge walkthrough we solved at the Cyber Grabs CTF 2022’s Junior edition.
Wayback 1
Some answers are hidden in the past, Whose website theme did we “cyberange.io” used when we first went public.
Flag Format: flag{firstname_lastname}
Solution
They have told us that the answer is hidden in the past. It’s a hint to use wayback machine. So I went to archive.org and searched for cyberange.io
In the search result, I saw that the site is live since 2016.
I have checked every screenshot starting from 2016 one by one and found the flag on a screenshot of 28th April, 2018.
I was looking for the theme owner and found this

#Flatfy Theme by Andrea Galanti
at the bottom of the page.
So, our flag is: flag{andrea_galanti}
Important: You have to submit the name in lowercase.
Thanks
