I have had a special interest for reverse engineering since high school. Since then, I have looked at all kinds of software, from bootloaders to userland applications. This has led to the discovery of various critical vulnerabilities in software, such as authentication bypasses, and memory corruption leading to remote code execution. Some of my public projects can be found on GitHub.
Reverse engineering is usually my favorite category in CTFs, although I enjoy the other categories as well. Some of my recent achievements are:
