Explore techniques for breaking into encrypted binary files through a hands-on workshop using a real-life example of encrypted 3D-printer firmware. Follow step-by-step instructions in a Jupyter notebook, learning various approaches including frequency analysis, known-plaintext attacks, floating point interpolation, and leveraging ARM architecture knowledge. Utilize tools like Matplotlib and SciPy to develop a framework for future reverse-engineering challenges. Led by Uri Shaked, co-founder of Wokwi and Google Developer Expert, this 52-minute session from Hackaday's Remoticon 2020 covers topics such as firmware analysis, encryption methods, and practical problem-solving in the field of embedded systems security.
