How To Install Ubuntu on Windows 11 (WSL) — A tutorial on how to install Ubuntu on Windows 11 using WSL. Probably unrelated to the OS course, since most of the time we’re gonna use the VM. But if you’re interested to “integrate” a fully functional Linux terminal into your Windows environment without having to install virtual machines, you can follow this tutorial and use WSL. WSLs are lighter.
A simple Format String exploit example - bin 0x11 — An example of how improper code development can lead to exploitations and unintended uses. In this video, a C code is vulnerable to a format string exploit, where the attacker is able to use printf() to control the stack and get what the attacker wants.
First Stack Buffer Overflow to modify Variable - bin 0x0C — Another example of how careless coding can lead to security bypasses. In this video, a C code is vulnerable to a buffer overflow exploit, where the attacker can overflow the stack with values the attacker inputs, hence allowing unintended uses such as getting the server shell.
