Description

Step into the world of hardware penetration testing - where technology meets curiosity! If you're experienced in traditional penetration testing, this course will open new doors, equipping you with the specialized techniques to target industrial embedded systems. Industrial devices present unique attack vectors and require a precise approach; here, you'll develop the expertise to identify hidden entry points within PCBs, firmware, and industrial IoT components.Starting with the fundamentals of electrical and signal reconnaissance, you'll learn the ins and outs of PCB hardware tools, delve into firmware and serial interfaces, and explore practical methods for exploiting these systems. This course is rooted in real-world case study industrial devices like a gateway and communication server. The Chronoguard Challenge Board bringing an authentic touch to your skill development. Each module is designed to deepen your understanding of how to leverage specialized tools like multimeters, logic analyzers, and flash programmers in your tests.By the end of this hands-on course, you'll have expanded your offensive hardware security toolkit with tactics tailored for the ICS/OT and IIoT domain, enabling you to craft advanced attack paths and discover vulnerabilities in industrial environments that remain untouched by traditional IT-focused methods. Elevate your penetration testing skills and gain the expertise needed to secure critical OT systems against the most sophisticated threats. Join now and be among the experts who can bridge the gap between IT and OT security.Disclaimer: Always prioritize electrical safety—avoid contact with exposed, voltage-carrying leads and be mindful of hazards. When applying these skills to industrial hardware, success is not guaranteed; debug interfaces are often undocumented or disabled. This course does not cover soldering skills; some basic craftsmanship and soldering knowledge are recommended for effective application.
