This challenge make me felt like I was an ancient Monk who knows old scripts. You will get it when you complete this challenge.
For any HackTheBox Challenge you need to first look for the Files that can be downloaded or Start instances with a given port on docker.hackthebox.eu and for any zip file first password is always hackthebox.
So, I downloaded the call.zip file and unzipped it with password "hackthebox" and a "scroll" image is there.
HackTheBox often consist of clues that can really help in understanding what needs to be done.
So, in this challenge we get to know that
I found the following message in a temple, I had the sensation that they were hiding something. Could you help me discover what it was?
As this hint suggests, message can be decoded in Temple. So, I googled for Temple Cipher and get to know about "The Ciphers of Monks" and tried decoding the image using the image below
And get to know how it works from https://www.dcode.fr/cistercian-numbers.
So, after decoding I get the Numbers like
72 84 66 123 77 48 78 107 115 95 107 78 51 119 33 125
Now, I got a hint from a Forum to convert this to ASCII code, so I searched for a Decimal to ASCII decoder and decode it and got the flag.
