In the previous post I’ve talked about creating and installing own Python packages using GitLab’s tools. Today I’d like to focus a bit more on the topic and show how you can make this process even better. We’re going to use GitLab’s CI to build the PyPi packages automatically. Problems Let’s imagine an average Cathy, […]
Hardware upgrades!
I’ve finally managed to upgrade my setup. I was hoping that I would be able to write a regular article, but due to the fact that I needed to return the monitor and waited for a week for another one, I still haven’t started writing it. Nonetheless I’d like to share with you what I’ve […]
How to Manage Project Dependencies with GitLab
Sometimes when we have a bigger project or a set of projects we want to extract some code in order to make it reusable. When integrating it with project we run into a question: how do I manage such dependencies (in GitLab)? Submodules and other Git Features One of the common approaches is using submodules. […]
What is Staging Area in Git?
If you’re a software developer, you’re likely using Git on everyday basis. It’s a very useful tool that hardly anyone learns to use properly. I’d say it’s a little bit like with driving cars: we learn for a moment, pass an exam, then we don’t do anything to boost our skills. Sure, with time we […]
Black Sheep Suspends
I hoped it wouldn’t happen, but looking back at last few months I must say I can’t meet the goals I’ve set for myself. I don’t have time to learn new things, last few posts have either been publishing materials I prepared earlier for a different occasion, or things that didn’t require much effort. This […]
Metasploitable Walk-through 1 – Reconnaissance

Welcome to the new series, which is going to be a tutorial-like walk-through of a popular metasploitable project. The main reason is that for some time I’ve been lacking ideas about how to learn and I decided to do something systematic, even if simple. For some time I was loosing interest in the topic, I […]
HackPy Part 4 – pcap files analysis with scapy

We’re slowly heading towards the end of our HackPy series. This time you’re going to learn a bit different way of sniffing – using scapy for offline pcap file analysis. It’s been a kind of a break for me since I was releasing materials prepared long before even I even started this blog. To be […]

Reinventing the low-level network tools would never be complete without famous Wireshark and I’m going to fill this gap today. How to perform network analysis with scapy? Before we begin, I’d like to remind you that you can sign up to the newsletter to get info about latest post and support me on Patreon. The […]
HackPy Part 2. – Nmap scanning





In the last post I showed you how to reproduce traceroute’s behavior. Today I’ll show how to do the same with another famous tool – Nmap and specifically its half-open port scanning using Python with Scapy library. This has some great benefits because apart from learning something and having fun, you can extend the desired […]
HackPy Part 1. – Traceroute





Hi. Welcome to the first post in the series, where I am going to show you the capabilities of Python in terms of building your own tools. I have showed those examples on two meetups, but I feel they are worth sharing here for those of you who did not have an opportunity to see […]
