Introduction

In this challenge, participants are tasked with performing OSINT (Open Source Intelligence) to uncover information leading to the discovery of a hidden flag. It appears that companies frequently experience document leaks, prompting the question of whether this particular company has encountered any such incidents.

Solution

Upon visiting the provided URL http://puffer.utctf.live:8756/, we navigated through the website and found a team section. Among the team members, Cole Minerton, the Marketing/Sales Director, caught our attention.

We searched for Cole Minerton’s social media profiles and discovered his YouTube channel. Despite initially seeming like a random channel, the channel description contained a Discord invite link.

After joining the Discord server and thoroughly going through the messages in one of the channels, we stumbled upon an attachment - a PDF document.

After downloading and examining the document, we found the flag written within.
