For our annual internal hacker conference dubbed SenseCon in 2023, I decided to take a quick look at Docker Desktop Extensions. Almost exactly a year after being announced, I wondered what the risks of a malicious docker extension could be. This is a writeup of what I learned, a few tricks I used to get some answers and how I found a “non-issue” command injection in the extensions SDK. Everything…

With docker though, I had quick reproducible build & run environments I could clean up easily without leaving a mess behind. The more I used docker, the more I’ve come to love it, and today it’s become a natural part of…

In this post I want to walk you through setting up a Raspberry Pi as a home server with all of your services running in docker containers with valid Let’s Encrypt certificates without exposing the Pi to the Internet.

These included dynamic routing protocols (referred to as DRP‘s) and first hop redundancy protocols (referred to as FHRP‘s). We decided to focus on these two classes of networking protocols to manipulate traffic flows and identify non-conventional ways of…
