What is DNS Tunneling?

Most organizations have a firewall that acts as a filter between their sensitive internal networks and the threatening global Internet. DNS tunneling has been around for a while. But it continues to cost companies and has seen hackers invest more time and effort developing tools. A recent study[1] found that DNS attacks in the UK alone have risen 105% in the past year. DNS tunneling is attractive–hackers can get any data in and out of your internal network while bypassing most firewalls. Whether it’s used to command and control (C&C) compromised systems, leak sensitive data outside, or to tunnel inside your closed network, DNS Tunneling poses a substantial risk to your organization. Here’s everything you need to know about the attack, the tools and how to stop it.
