Challenge write-ups [Sticky]

I will post write-ups of challenges in this blog.

Write-ups for challenges which aren’t yet archived or aren’t open for write-ups, will be password protected with the challenge or root flag, unless noted otherwise (i.e. I didn’t manage to own the root account yet).
Tip: the password will follow the syntax of the platform.

Hit me up on Twitter if I’ve forgotten to open up a write-up after the window has opened.

Do not share content of my write-ups:

  • when this is not (yet) permitted by the challenge owner;
  • when this is not (yet) permitted by the challenge platform;
  • without reference to my original post.

Current platform I use to play challenges, CTF, …:
