Contribute to professormahi/CTF development by creating an account on GitHub As a note, there are several other PDF forensics tools that are worth to be mentioned: [Origami] (pdfextract extracts JavaScript from PDF files), [PDF Stream Dumper] (several An easy way to do this if you are not an expert on PDF standards is to run the same tools on a plain PDF and compare the results with the challenge PDF results. During this peepdf is a Python tool to explore PDF files in order to find out if the file can be harmful or not. The PDF format is known for its complexity and potential for concealing data, making it a focal point for CTF forensics challenges. In a CTF context, Forensics challenges can include file format analysis, steganography, memory dump analysis, or network packet capture analysis In the computer forensics context, PDF files can be a treasure trove of metadata. File identification. Metadata can be stored in a PDF document in a document information dictionary and/or in one or more metadata streams To fully understand network forensics, we must first A comand-line tool to recover a password from a PDF file.
