Best hands-on experience you can get
If you’re comfortable with ROP and if you want to take a deep dive into the world of heap exploitation, I can highly recommend this course. Peter is an excellent and inspiring teacher and researcher that’s able to explain even the most complex aspects of the heap in a structured manner. He really cares whether his students understand the material in class and he even provides exercises that should last for months after the class has finished.
This is the best hands-on experience you can get and if you’re willing to learn, this is for you.
