A C2 (command and control) channel is the covert communication path attackers use to control compromised hosts and exfiltrate data after a breach.
Command and Control Channel (C2) Definition: A C2 (command and control) channel is the covert communication path attackers use to control compromised hosts and exfiltrate data after a breach.
A command and control (C2) channel is the communication path that an attacker uses to remotely manage compromised systems and exfiltrate data after an initial breach. Malware beacons out to attacker-controlled infrastructure over protocols such as HTTPS, DNS, or messaging services, often disguised within normal traffic to evade detection. Disrupting C2 channels is a key defensive goal, since cutting them off can neutralize an active intrusion.
Command and Control Channel (C2) is one of the topics you'll master in the CEH Boot Camp.
