DNS is a critical foundation of the Internet. There would be no way to get to websites without it, except by entering numerical IP addresses. Like so much on the internet, the power that makes DNS beneficial for everyone can be abused by a few for the detriment of many.
Unit 42 researchers have released a report showing how attackers can abuse DNS to hide their tracks when they infiltrate networks and steal data using a technique known as “DNS Tunneling.” This research can help organizations understand DNS-based threats and the risks they pose to their environment.
