In OSINT and Post-exploitation phases, it is quite common to run automated parsers and search utilities to mine interesting information. Imagine that you have access to a file server with hundreds of documents and you are searching for a single author!!!
In this exercise, you will mine a set of PDF documents and print different metadata information available in the documents.
You will be programming using a Jupyter Notebook. We would recommend going through the basics online, if you have never used them.
Once you start the lab, the lab questions can be viewed using the file challenge_3.ipynb
The Python library you can use to solve this challenge is PyPDF2. It is already installed in the lab system.
One possible solution is available in the file: challenge_3_solution.ipynb

Technical Support for this Lab:
There is a reason we provide unlimited lab time: you can take as much time as you need to solve a lab. However, we realize that sometimes hints might be necessary to keep you motivated!
We currently provide technical support limited to:
- Giving hints for a lab exercise
- In rare circumstances, if you have totally given up (NO!!!) then tell you how to solve it. This will be limited to sharing the solution video or lab report
- A lab exercise fails to load or has errors in it
If you need technical support, please email email@example.com clearly mention the name and link of the lab exercise and other essential details. The more descriptive you are, the faster we can help you. We will get back to you within 24 hours or less.
For adminitrative queries, billing, enterprise accounts etc. please email firstname.lastname@example.org
