I started studying cyber security in school and we got a CTF assignment, finding a “flag.txt” file within a password protected PDF.
After finding the password for the file, I tried using pdfdetach, pdf-parser and pdf_hide to look for files inside the PDF, but couldn’t find anything. a Google search also came up with no results as to how I could approach this.
Am I doing anything wrong? I’m not looking to get a solution, just a little hint.
