UIUCTF 2021 PwnyOS 1.1 Challenges

PwnyOS is a custom operating system that was developed for uiuctf 2020 and made a return in 2021 with a new version(1.1). I found it a very interesting idea that taught me a lot about how things work at a lower level in operating systems and computers, so I’d like to thank Ravi for taking the effort to create the OS and these challenges.
