This is the second part of my adaptation of …ing the technical interview, a blog series by Aphyr about writing programs in funny, non-standard ways. Again, this is a writeup of a CTF challenge I created. Specifically, the dive in the lake challenge of LakeCTF, organized by EPFL’s CTF team, polygl0ts.
I really like the blog series …ing the technical interview by Aphyr. Besides the humor, I enjoy seeing Turing completeness in parts of systems that many people use but that were not designed to write entire programs in.
Ghidra is a fairly complex reverse engineering tool, that has a lot of great features, that are not really intuitive to use. This talk was given together with intrigus for our CTF team KITCTF. It touches on many interesting but not easy-to-use features, specifically:
With my CTF team KITCTF, each semester we do introductory talks about how to get started with CTFs. I prepared an introductory talk about reverse engineering, which is meant to provide the absolute basics. You can find the slides here.
I talked about how C++ reverse engineering is very different from C reverse engineering.
The talk touches on a research project I did at HexHive about a subtopic in that space.
However, it is meant as a general introduction.
Unfortunately, I can only provide the slides and not the live demo.
These are 2D slides, so use n and p to navigate instead of the arrow keys.
Note: Navigate the presentation with n and p keys. The slides are 2D.
