What are Command and Control Attacks?

As the cyber landscape expands, malicious actors have evolved beyond simply breaching systems. Cyber criminals now aim to maintain an undetected presence to control the system and extract the data according to their needs. Command and Control (C2) attacks create a covert link between the compromised system and the C2 servers, enabling prolonged access. This prolonged connection allows cyber actors to execute various malicious activities such as data theft, distributed denial of service (DDOS) attacks, or complete network compromise by threat actors. These attacks highlight the critical need for robust security measures to defend against such threats. We can effectively safeguard our systems from these evolving cyber threats by implementing robust security measures and mitigation strategies.

Malicious attacks have become increasingly common, with one especially harmful method exploiting DNS for C2 purposes. This insidious technique enables threat actors to establish covert channels with compromised devices over a network. C2 attacks typically involve one or more covert channels, depending on the nature of the attack. These channels range from simple and direct communication to intricate and resilient structures. Attackers use these varied communication channels to execute various malicious activities, including deploying additional malware payloads, creating botnets, and exfiltrating sensitive data. This underscores the importance of understanding and defending against these sophisticated threats.
