GreHack is an international security conference, so the only requirement regarding format is the use of English language. Apart from that, we do accept any format and companion materials (classical academic paper, short paper, slides, video, demo with comments, state of the art, relevant work...) you may judge appropriate to present your submission and convince the PC members that your work deserves to be presented at GreHack 2025.
