Bash isn’t just an interface to your daily laptop - it’s a weapon. In this hands-on workshop, we’ll push bash beyond its typical use, leveraging it for hacking, data processing, automation, and real-world security applications. Whether you’re crafting exploits, analyzing massive datasets, or automating reconnaissance, this session will equip you with the skills to turn bash into your ultimate hacking tool.

This talk explores the reverse engineering of the proprietary DUOX PLUS intercom system, focusing on its digital signaling, identification methods, and security weaknesses. Using hardware tools like oscilloscopes, logic analyzers and breadboards we demonstrate MITM attacks, spoofing, and signal manipulation. Attendees will gain hands-on insights into decoding and interacting with closed digital protocols, exposing vulnerabilities in real-world access control systems.
