DNS security is a lesser known and often overlooked field in cybersecurity. Did you know that it only takes a few button presses and commands to completely take over a company’s website or retrieve all their subdomains? DNS vulnerabilities are mind-blowingly naive, easily neglected, ubiquitous, yet surprisingly powerful.

In this session, we will explore a few common DNS vulnerabilities and their causes, then demonstrate the severity of these issues with a study on the top 100 companies. We hope to raise awareness on DNS security and teach the audience how to detect and fix these issues.
