OSCP

This repository contains the knowledge you need to obtain the OSCP certification.

Specifically, I have organized all the knowledge needed for OSCP into the following nine different modules.

09 – Report Writing

In the ./report you will find a folder ready to be used for the final exam. The idea is simple: you write your exam findings in a report using either the markdown or org markup languages, and then you can use the generate.sh script to generate a final PDF. Two sample reports report.md and report.org are presented. You can take inspiration from those and customize it to your own need.

To actually generate the report, make sure you have pandoc installed with the latex theme eisvogel. If you do not have such file I suggest to download it from github.

wget https://raw.githubusercontent.com/Wandmalfarbe/pandoc-latex-template/master/eisvogel.tex

Then, edit the script ./report/generate.sh in order to insert your own OSID value. So for example assuming my OSID was 99999999 then I would write on top of the file

OSID=99999999

Finally, just execute ./generate.sh, and you should see the following

[leo@archlinux report]$ ./generate.sh 
[INFO]: Checking requirements
[INFO]: All good, we're ready to generate!
[INFO]: Generated succesfully, creating 7z archive!
[INFO]: MD5 of archive (e9b9424d742bf230748665cd614ba240)

After the script has succesfully executed, you will see two new files:

  • OSCP-OS-99999999-Exam-Report.pdf, which contains the generated pdf for previewing
  • OSCP-OS-99999999-Exam-Report.7z, which contains the final artifat you can use to submit your record.

Notice how at the end the MD5 of the artifact is computed. This can be used during OffSec upload procedure to make sure you uploaded the correct file. Finally, if you want to change the input filename to export, just give an argument to the generate.sh script as follows. Just remember that the scripts only supports markdown and org syntaxes.

./generate.sh report.md
./generate.sh report.org
