MOSE is an open-source Go binary that translates a single command or script into Puppet/Chef/Ansible/Salt payloads, automating discovery of where to place backdoors, secrets harvesting, and deployment across agents. A demo compromises a compromised Chef workstation, uploads a payload, and gains reverse shells and a web shell, reintroducing SSH keys via agent runs every ~20 minutes; earlier engagements escalate from one Jenkins key to ~15 hosts then a puppet master to hundreds of servers. Test labs (Docker/Vagrant) exist and the tool works as shown.
