Sharpshooter, Python2.7, and Pip2 Installation

Newer versions of Linux may not come with any sort of Python 2 installed. I recently wanted to run Sharpshooter, which is a “payload creation framework for the retrieval and execution of arbitrary CSharp source code.”

Problem is, Python 2 isn’t installed by default on Ubuntu 21.xx and neither is pip2. You also need to install an older (I think) version of jsmin – at least that’s what worked for me.

Use this script to install everything and get it up and running.

if [ "$EUID" -ne 0 ]
    then echo "Run as root!"

# clone sharpshooter from github
git clone

add-apt-repository universe && apt update

apt install git curl

# install python2.7 and pip2
apt install python2.7 -y
curl --output
chmod +x ./
sudo python2.7 ./

# install correct jsmin
tar xzf jsmin-2.2.2.tar.gz
python2.7 ./jsmin-2.2.2/ install

Evasion Techniques and Breaching Defenses (PEN-300) – OSEP – Initial Thoughts

I just started this course the other day. I’m already neck deep in VBA, C#, and Powershell, which I need more experience in anyway. I had to do some C# for the AWAE/OSWE and I’ve written a couple very small web apps in C#. I’ve done a very minimal amount of Powershell, though I’ve been meaning to change that.

I know a lot of people say the OSCP is lacking in Active Directory attacking, which may be true. I’d counter by saying what the OSCP doesn’t cover, PEN-300 will cover. The courses go hand in hand. My early opinion is that anybody that takes and passes the OSCP should do PEN-300

All in all, I’m pleased so far. I’m only about 1/7th of the way through the PDF, though. I have a lot to go. With all that I have going on IRL, I’m not sure I’ll be able to finish it in the two months I’m allotted – I may have to get an extension.

My plan is to pass the OSEP exam in October and then start the EXP-301 course and pass that exam by the end of the year. This is an aggressive, and probably unrealistic goal, but oh well, haha.

Anyway, I’ll be back with a full report after the exam.
