The D-Link DIR-878 is a Wi-Fi router that reached its End of Life. Many vulnerabilities were discovered on this device. Today, my task was to help a colleague of mine in its master thesis research project. His project concerns analyzing, studying and locating well known vulnerabilities in firmware. He shared me a curated list of vulnerabilities which needed some analysis so that their data could be added to its thesis. It is important to note that even though I performed this analysis, I have no merit in the content of his thesis whatsoever....

This was an old post I originally wrote the 24th of October 2018. I recently discovered it in the drafts of this blog. At the time, I was planning to do this challenge on many other languages, but ended up abandoning. I decided to publish it today. It is a short one, enjoy! Cloudflare’s email-decoder in one line I’ve recently “decrypted” Cloudflare’s email-decode.js, this is my take on writing some one line decoders for it....

I switched from my old and beloved hugo-dusk theme, to the new flashy and shiny PaperMod theme. Why? The old theme development has been dropped and I was basically maintaining it myself. I added some (debatably) cool stuff to it, but it was time to let it go.

I know, I know… It’s been almost two years since the last time I wrote here. Well.. I had stuff to do! I am still studying for my masters degree, but I had some major step forwards in many other directions. One of those was picking up NixOs, a great operating system powered by the almighty Nix package manager. There are various reasons behind this choice and I will probably expose them once I installed it as my main system on most of my boxes....
