Repository Practices for the Dark Arts: When Openness Conflicts with Safety

Open science principles increasingly demand that research data be findable, accessible, interoperable, and reusable (FAIR), yet cybersecurity research, particularly malware analysis and threat intelligence, exists in a paradox. The artifacts that underpin reproducible research are the very materials that could enable harm if openly shared. This proposal presents an initial open question at the intersection of open science and cybersecurity research. The main aim is to promote dialogue within the community on developing repository practices, ethical frameworks, and technical architectures that balance legitimate research needs against security risks, asking: how can repositories be "open to all" when the data itself can be weaponised?
