Actions are special messages that don't adhere to the normal message types that you see for the rest of the features in this section. There are only a handful of these messages:
​Action: Checkin - Initial checkin messages and key exchanges
​Action: get_tasking - Getting tasking
​Action: post_response - Sending tasking responses
Inside of this is where the features listed throughout this section appear
​Action: upload - Uploading files from Mythic to the agent
This is a special case. Downloading files from agent to Mythic happen within the post_response messages, but moving files from Mythic to agent happens with the upload action
