Threat of the Month: DNS Tunneling Attacks
DNS tunneling is a difficult-to-detect attack that routes DNS requests to the attacker's server, providing attackers a covert command and control channel, and data exfiltration path. Bad actors use DNS tunneling to get data through firewalls. Suspicious DNS traffic can be difficult to detect because DNS is a noisy protocol, making it harder to distinguish a normal host query and normal DNS traffic from malicious activity.
