About Maximilian Kaul
I’m a web application security penetration tester located in Munich,
Germany. I studied in Stockholm, Sweden at the Royal Institute of
Technology (KTH) in the Computer
Science program. Before that I studied Computer Science at
Heidelberg University (Germany) where I received a Bachelor degree in
2015. You can read about my university
My main interests are with security, Linux (which I have been using
almost exclusively for about 10 years now), algorithms and C++. I wrote
my master thesis on “Ransomware for the Internet of Things” with
Shaid Raza at RISE. You can find my CV

Started to work in Munich, Germany :)
I just learned that I passed my Master thesis. Next step: finding a
job. Preferably in the computer security area (e.g. pentesting /
security engineering) or in software engineering (e.g.
I started to solve problems on Open Kattis. We used the platform for
some courses at KTH and I like problem solving so the shoe fits :)
I’m around rank 250 and aiming for top 100.
All the old photos migrated away from my website and are now part of
Jana’s sand-islets.de website. So
if you have old bookmarks don’t be surprised if the photos are no
longer at their usual place. I put a note at all the old locations with
a link to the new gallery on Jana’s website.
I polished most of the website’s style following Butterick’s amazing book on
typography. I hope you like it. Suggestions for further improvements
are always welcome ;)
factor authentication is now enabled for Roundcube and Nextcloud (I’m using FreeOTP on my phone). Next milestone:

Please stop using my
old GPG key
FFF578DA. My laptop and backup got stolen so I no longer have
access. The keys are not compromised. Laptop and backup are encrypted.
I’m sorry for the inconvenience. My new
key is available here. Unfortunately the old key can not be revoked
since all 3 copies of the revocation certificate were on now stolen
Starting now all my hosts use Let’s
Encrypt certificates. There are no warnings to be expected because
the keys have been pinned in
