Summary
Peer-to-peer communication over a network socket. Apollo will bind to a specified port and await an incoming link request before establishing communications back to Mythic.

Profile Options
The TCP C2 profile is designed to be used for internal network communication, and therefore will need to egress from a network through an agent using the HTTP C2 profile. All HTTP agents have the ability to communicate with TCP agents and manage peer-to-peer connections using the link and unlink commands.
Profile Options
Crypto type
Leave as aes256_hmac.
Port to start Apollo on
Self explanatory. Note: If medium integrity or lower, this will prompt a request to allow the binary to bind on the specified port.
Kill Date
The date at which the agent will stop calling back.
Perform Key Exchange
Perform encrypted key exchange with Mythic. Recommended to leave as T for true.
