Attack communication traffic is usually hidden with various techniques and
tools, including:
Encryption with SSL, SSH (Secure Shell), or some other custom or proprietary encryption
Circumvention via proxies, remote access tools, or tunneling. In some instances, use of
cellular networks enables complete circumvention of the target network for attack C2 traffic.
Port evasion using network anonymizers or port hopping to traverse over any available open
ports
Fast Flux (or Dynamic DNS) to proxy through multiple infected endpoints or multiple,
ever-changing C2 servers to reroute traffic and make determination of the true destination
or attack source difficult
DNS tunneling is used for C2 communications and data infiltration
