ronin-payloads is a Ruby micro-framework for writing and running exploit payloads. ronin-payloads allows one to write payloads as plain old Ruby classes. ronin-payloads can be distributed as Ruby files or in git repositories that can be installed with ronin-repos. It's like `msfvenom` but simpler and more modular.
