OFFENSIVE SECURITY & REVERSE ENGINEERING (OSRE) Course

This repository is for the Offensive Security and Reverse Engineering Offensive Software Exploitation Course I used to teaching at Champlain College and currently sharing it for free online (check the YouTube channel for the recordings). Most of the slidenotes I used, are already shared on HTID Course, but the labs were fully created by myself. I used publicly available resources and software to explain each of the weakneses covered, so there is nothing here that you cannot find online.

OFFENSIVE SECURITY & REVERSE ENGINEERING (FULL COURSE / 2021)

This is the whole course that was covered at Champlain College during Spring 20/21, yes during the COVID-19 pandemic! Unfortunately I was not able to cover all the modules due to time limitation, but other than that I had a great semester with my students and enjoyed teaching this course to them. Big thank you to each one of them, who all graduated now. The course could be found here OSRE. The videos on my YouTube channel walk through most of them.
