Training Objectives:

The goal of this training is to give participants the skills necessary to identify critical medical device vulnerabilities, exploit medical vulnerabilities and implement software or hardware fixes. The training will have a hands-on approach and CTF style format where the skills learned will be applied on hardware, software, firmware and wireless targets.
