I’ve recently done a pet project on Django and AWS to better get to know those 2 platforms. Unfortunately I’m unable to deliver enough tutorials to justify maintaining the entire environment, but I’m eager to share my experience, what went well, what went wrong.

On Python, Mutability, Copy and Deepcopy
I’ve just been hit by a very interesting problem in a project, on which I work. I needed to extend some code my colleague wrote. I did it, but when I added tests, I discovered that when I run the single test I added, it’s all fine. However, when I run it in a group […]
How does Yubikey help to protect against phishing
Recently I wrote about the new security device I bought. Today I want to give a hands on example of how it improves my security. Ladies and gentlemen, today I’ll perform an attack on myself (since it’s the only legal attack I can perform) and explain in better details how to use Yubikey against phishing. […]
Metasploitable Walkthrough Part 2. – VSFTPD
It’s been over a year since I’ve done something security-related and today I’m continuing the series about the Metasploitable project. The last part was reconnaissance, where I showed multiple vulnerabilities found on the machine. One of them was related to the VSFTPD. Today I’ll just script the attack. What is VSFTPD Vulnerable to? There’s a […]
AWS Lambda in Pycharm
I’m back to life and here’s some tasty article on something I’ve recently learnt. Unfortunately, this is again on 2 very specific commercial solutions instead of general purpose programming. And another one on AWS. Maybe I’ll come up with an article on signal handling in operating systems. Anyway, here are some tips and trick on […]

How to Manage Project Dependencies with GitLab – Part 2.
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, […]
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 […]

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 […]
