1. Introduction

In this lab, a disk image file “evidence.img” is provided in the home directory of the root user (/root/). One of the PDF files present on the disk contains the flag.

Guidelines:

  • pdftotext tool can be used to convert PDF files into text files.

2. Filecarving with scalpel

scalpel evidence.img -o output

Seems that I’ve to edit the config file first which is located under /etc/scalpel/scalpel.conf

vi /etc/scalpel/scalpel.conf

We search for pdf files therefore, I’ll „uncomment“ the lines which are responsible for pdf files

Save the file and give scalpel a new try:

scalpel evidence.img -o output

3. Retrieve the flag

Let's browse to the output directory and use pdf to text to reveal the flag

4. Summary

Extract files from the given image using tool and retrieve the flag!
