Short-term (ST)—also called short haul—C2 are those C2 servers on which the beaconing process will continue. Whenever a system in the targeted organization executes our payload, the server will connect with the ST-C2 server. The payload will periodically poll for tasks from our C2 server, meaning that the target will call back to the ST-C2 server every few seconds. The redirector placed in front of our ST-C2 server is called the short-term (ST) redirector. This is responsible for handling ST-C2 server connections on which the ST-C2 will be used for executing commands on the target server in real time. ST and LT redirectors would get caught easily during the course of engagement because they're placed at the front.
Long-term (LT)—also known as long-haul—C2 server are where the callbacks received from the target...
