MOSE is a post-exploitation tool that enables security professionals with little or no experience with configuration management (CM) technologies to leverage them to compromise environments. CM tools, such as Puppet, Chef, Salt, and Ansible are used to provision systems in a uniform manner based on their function in a network. Upon successfully compromising a CM server, an attacker can use these tools to run commands on any and all systems that are in the CM server’s inventory. However, if the attacker does not have experience with these types of tools, there can be a very time-consuming learning curve.
