Nissen
Reverse engineer, malware analyst, digital forensic specialist.
By day, I investigate cyber crime and disrupt cyber criminal networks.
By night, I torture myself with cursed CTF challenges with Brunnerne to satisfy that deep, insatiable craving for fake internet points.
This site is my space to gather and share my projects, CTF challenges, writeups, and any technical insights I uncover along the way.

RECENT CHALLENGES
My challenges are currently available with source and writeups (for most) from my GitHub: NC3 CTF 2023 and DDC + other. Note, some of these are for Danish CTFs and have been created in Danish.
This page will later likely just contain an index of the challenges.
RECENT WRITEUPS
All writeups are currently still on my old page and will be moved at a later point in time: Writeup site
