An Introduction to C for Windows (PDF, 0.52MB)Published: 03 Apr, 2026
Created by:

Jonathan Reiter

This poster is aimed at newer C developers coming from other operating systems and switching to Windows. It is a quick reference resource that also captures the first several parts of the Intro to C workshop series. If you haven’t gone through that series, you can find that here.

The last portion of this poster is a small Spot the Bug challenge. For those who are new to C, this is for you. If you think you have found the bug, please email me at jreiter@sans.org for a shout out below!

This poster has been created as a reference for the SEC670: Red Teaming Tools - Developing Windows Implants, Shellcode, Command and Control course by the Certified Instructor Jonathan Reiter.
