Hello there 👋
Hello there, I am ckrielle, a CTF player and general (low level) security enthusiast. I’m generally interested in system and OS level concepts through the scope of reverse engineering and binary exploitation. This blog will have writeups from CTFs I play in, any personal research/experimentation I do, and anything else I’d like to write about. If you wish to contact me, feel free to do so either through Twitter, or through Discord at ckrielle.
