Profile Options
The SMB 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 SMB agents and manage peer-to-peer connections using the link and unlink commands.
