An artifact hub is a repository platform for storing and sharing build artifacts such as code packages, machine-learning models, datasets, binaries, or configuration files. In normal software workflows, these hubs help teams version content, distribute releases, and reuse trusted components across projects.
In cyber security, artifact hubs matter because attackers can abuse their trust and visibility. A malicious file, package, or model placed in a public hub may be downloaded by developers, CI systems, or automation tools that assume the content is legitimate. Defenders therefore treat these platforms as part of the supply chain: they verify publisher identity, inspect metadata and hashes, restrict permissions, and monitor for suspicious updates or unexpected dependencies.
