I enjoy fixing things by breaking things. I have been using and administering UNIX/Linux systems since 1995. In early 2017, I joined a penetration test team specializing in offensive security. In 2019 I moved to the red team. In my personal time, I conduct security research focusing on discovering vulnerabilities in open and closed source software. Visit my research page for a list vulnerabilities. Some of my exploits and tools can be found on at my Github repo https://github.com/mirchr.
In the past I have worked on some public and private bug bounty programs with the primary goal of learning. The majority of my bounty work was focused on finding elevation of privilege vulnerabilities in Windows, macOS, and Linux applications.
