Capture The Flag

A key highlight of the event, the Cyber On Board Embedded CTF offers a hands-on immersion into the operational realities of embedded systems cybersecurity. Designed by NEVERHACK teams, this Capture The Flag challenges participants with realistic, high-stakes scenarios, far from traditional academic exercises.

Capture
The Flag

The 2026 edition is built around an Automated Guided Vehicle (AGV): a critical autonomous system at the heart of real industrial challenges, to be analyzed, compromised, and then secured. This will be a hardware-oriented, non-simulated CTF based on physical equipment. Challenges will focus on understanding integrated circuits and interactions between components. Solving them will require signal analysis, identification and characterization of components, as well as exploitation of information derived from the hardware environment. The objective is to assess participants’ ability to reason, investigate, operate, and progress methodically when faced with a concrete technical problem. This requires strong analytical thinking, technical curiosity, discipline, and effective teamwork.

The awards ceremony will take place on Day 3 at 12:00 PM.

Training the next generation: This CTF will take a hardware-oriented approach, based on real, physical hardware rather than simulations. The challenges will invite participants to explore how integrated circuits work and to understand the interactions between different electronic components. Solving the challenges will require in-depth analysis, including signal analysis, component identification and characterization, as well as the use of information gathered from the hardware environment. Beyond technical skills, this exercise aims above all to assess participants’ ability to reason, investigate, and proceed methodically when faced with a concrete problem. Curiosity, rigor, analytical thinking, and collaboration will be key to overcoming this challenge.
