OWASP WebGoat XSS lessons

I recently installed WebGoat, a deliberately vulnerable web app with built-in lessons. While some of the lessons are very easy, they quickly rise to a much higher difficulty. Even though the app does explain the basic concepts, the explanations are nowhere good enough to solve the exercises provided. In this post I’ll focus on the Cross-Site […]

DVWA login brute-forcer in Python

I recently started playing around with the Damn Vulnerable Web Application, a PHP/MySQL web app for security researchers and students. It is, as the name implies, damn vulnerable. After installation of DVWA you’ll be presented with a login page. Unless you supply the user and password from the manual you’ll have to get access some

Decoding base64 in Python

This is a small tutorial for beginners on how to decode base64 text strings in Python3. While Python does have a function to directly encode and decode base64, it is always good practice to try and write one yourself if you are a new programmer. Head over to Wikipedia to see how base64 is decoded. First,

Lego 21309 Saturn V Review

In April 2017 Lego unveiled the new Lego Ideas Saturn V rocket, a project I had supported on Lego Ideas. As soon as I saw the final model and its price tag, I knew I had to get it. The wait was rather long since it got sold out at the Lego online store on the very

Arduino Lego Robot – Update 1

I’ve been building  an Arduino powered Lego tracked robot on and off for the past half year, and have finally come to the point where there’s something to show. I didn’t take long to realize that I had to become proficient in programming and not just patch together other people’s code from the web, so

My Model Shipyard

For the past 15 years or so I’ve been building model sailing ships on and off. This has resulted in 2 finished kit models, one of them modified, and one scratch-built model still under construction. I’ve had some pictures of my ship models on several websites, but what with the nature of the web, most

Audio Selector

I usually change a lot between speakers and headphones on my PC – Speakers when I watch movies or listen to music, and headphones when I’m at the desktop. I hate having to insert and remove the jack every time I want to change, so about a year ago I bought a cheap audio selector

Arduino & Lego PF Motors

Working through the book Arduino Workshop by John Boxall I’ve finally come to the chapter describing how to build an Arduino Tank Robot. However, instead of buying a premade robot chassis I decided to make it out of Lego Technic instead, something I played a lot with as a child. This presented me with some interesting
