In this episode, we dive into the technical complexities of DNS resolution in the context of ASM asset discovery. Join us as we discuss the challenges, implications, and solutions we have encountered while dealing with DNS resolution at scale. From DNS wildcards to security scanning considerations, we explore the importance of DNS data and its role in comprehensive reconnaissance. Our hosts, Michael and Shubs, share their experiences and insights gained from years of perfecting DNS resolution for asset discovery. Discover how DNS records play a crucial role in security scanning, including the detection of DNS misconfigurations and potential security risks. Learn about a fascinating case of DNS poisoning at scale and how it was detected and exploited. Gain valuable insights into the differences between IP-centric tools and a subdomain-centric approach to reconnaissance, highlighting the importance of focusing on DNS data for comprehensive attack surface mapping.
