Twaiq bootcamp ctf 2025 - Forensics

Hi, I’m Depe.. and in this post we gonna go through the forensics challenges from the Twaiq Bootcamp CTF.
The challenges were honestly kinda basic & trivial (at least for me) but since i had nothing better to do i thought why not.. also it was the perfect excuse to waste some time (i was not totally procrastinating studying a(tra)ctive directory 🤓)

Forensics 01

challenge description :

the file came from an unknow source. Can you figure out who created it ?

And this weird-looking “ugly” windows image was given

solution

As hinted in the challenge description … the source word indicates that there is something hidden in the meta-data

what is Metadata ?

Quoted from NCEI
Metadata, or "data about data", is structured information that describes, explains, or provides context for other data, making it easier to find, use, and manage. It includes details like an item's creation date, author, format, and purpose, serving as crucial documentation to understand the data's history, quality, and intended use.

so as hinted in the challenge i investigated the meta-data of the image using exiftool (faster) and took a closer look at them.

looking at the Author section we can see the flag, and that was the soultion.
