ConnectBack ConnectBack malware is a type of malicious software designed to establish unauthorized connections from an infected system to a remote server. Once a victim's device is compromised, ConnectBack creates a covert channel for communication, allowing the attacker to remotely control and gather sensitive information from the compromised system.
