Introduction

In this challenge, we are presented with a scenario where signing a magical contract accidentally involves the flag instead of one’s name. It’s a common mistake, right? Contracts… they can be tricky.

Solution

We were provided with a PDF file to examine. Despite a thorough search, no hidden flags were found within the text of the PDF. However, not all hope was lost. By using the handy tool extractpdf.com, we managed to extract images embedded within the document.

One of these extracted images contained a flag, which only participants with the most advanced skills could solve.
