Linux Reverse Engineering CTFs for Beginners | 🔐Blog of Osanda
After a while, I decided a write a short blog post about Linux binary reversing CTFs in general. How to approach a binary and solving for beginners. I personally am not a fan of Linux reverse engineering challenges in general, since I focus more time on Windows reversing. I like windows reverse engineering challenges more. A reason me liking Windows is as a pentester daily I encounter Windows machines and it’s so rare I come across an entire network running Linux. Even when it comes to exploit development it’s pretty rare you will manually develop an exploit for a Linux software while pentesting. But this knowledge is really useful when it comes to IoT, since almost many devices are based on Linux embedded. If you want to begin reverse engineering and exploit development starting from Linux would be a good idea. I too started from Linux many years ago. Saying that since some people when they see a reverse engineering challenge they try to run away. So if you are a newbie I hope this content might be useful for you to begin with.

[] [#1] Hello, world!
"In this series we will cover the fundamentals of virtualization in the 64-bit Arm architecture and develop an accompanying hypervisor step-by-step, beginning with simple examples hosting trivial virtual machines and working up to hosting fully-fledged operating system kernels such as Linux. Topics discussed will include device tree spoofing & stage 2 address translations, CPU feature spoofing & instruction emulation, device emulation, virtual interrupts, firmware interactions, and more."
