At the time of writing the coronavirus is raging the earth. Very soon after the outbreak, visualizations of both the virus and the effect of the disease started to appear everywhere. As I partially graduated in the subject of data visualization, I have always been interested in those graphs. Lately, I followed an introduction course to visualize data with D3.js. After I completed this course, I wanted to draw some meaningful graphics with this library. So follow along when I explain a little bit about D3 and then draw a simplified version of the coronavirus molecule.

Welcome to the blog series about how to hack a box! In this first post I’ll guide you through the global steps you can take to hack a box. The steps are universal, so you can use them on any target which you have permission for.

As a developer, you are familiar with Docker. You push your images to the Hub, use Compose locally and know a thing or two about Kubernetes. Or…​ Well…​ To be honest…​ You don’t. And you are ashamed you don’t know anything about it. You browse the internet and it’s so overwhelming. So you stop looking and continue what you’ve been doing all the time. Deep inside, you still wonder. Can’t anyone not just explain Docker in simple terms? Is it really this hard? Or am I just missing something really obvious?

In my last blog I gave you a small introduction into the term "Reverse Shell". I described it as: "A Reverse Shell is where your target machine creates a connection to your machine, after which you get a shell on the target machine in which you can execute system commands." It is similar to SSH, but without any encryption and the connection is created the other way around (from target to you, instead of you to the target).
