To hide or reduce their digital trail, cybercriminals constantly buy and discard cheap domain names to use as part of their attack infrastructure. To stay ahead, brand management companies monitor daily zone files for potentially infringing base domain names. Yet the bad guys adapt and have learned to abuse DNS in new ways to avoid detection.

In this session, Internet pioneer and Farsight Security CEO and Cofounder Dr. Paul Vixie will examine the less-well monitored "dark corner" of the Internet where infringing names live created at the hostname (or "fully qualified domain name") level. By shifting the infringing mark from the base domain to the hostname, the bad guys can still efficiently attract potential visitors via search engines, but they can avoid getting flagged during daily zone file scans. From there, bad actors can use these infringing domains to lure unsuspecting users to fake websites to sell counterfeit goods, commit phishing attacks to secure entry into networks and more.

Dr. Vixie will discuss how passive DNS sheds light on these shady DNS cyberattack techniques. He will also discuss the challenges of monitoring the Internet's domain names on a per-host level, and illustrate solutions that are relevant to any brand owner or brand management consultancy.
