Talk#1: A New Class of DNS Vulnerabilities Affecting Many DNS-as-Service Platforms
We present a novel class of DNS vulnerabilities that affect multiple DNS-as-a-Service (DNSaaS) providers. The vulnerabilities have been proven and successfully exploited on three major cloud providers including AWS Route 53 and may affect many others. Successful exploitation of the vulnerabilities may allow exfiltration of sensitive information from service customers' corporate networks. The leaked information contains internal and external IP addresses, computer names, and sometimes NTLM / Kerberos tickets. The root cause of the problem is the non-standard implementation of DNS resolvers that, when coupled with specific unintended edge cases on the DNS service provider's side, cause major information leakage from internal corporate networks.
In this research, we detail a specific vulnerability that is common across many major DNS service providers that leads to information leakage in connected corporate networks. Specifically, we show how Microsoft Windows endpoints reveal sensitive customer information when performing DNS update queries. The security risk is high. If an organization's DNS Updates are leaked to a malicious 3rd party, they reveal sensitive network information that can be used to map the organization and make operational goals. Internal IP addresses reveal the network segments of the organization; computer names hint at the potential content they may hold; external IP addresses expose geographical locations and the organization's sites throughout the world; and internal IPv6 addresses are sometimes accessible from the outside and allow an entry point into the organization. The impact is huge. Out of six major DNSaaS providers we examined, three were vulnerable to nameserver registration.

Talk #2: Redefining Threat Modeling: Security team goes on vacation
Threat Modeling is an important part of every company's Security Development Lifecycle, but as development teams grow bigger Security will either have to choose which features they want to Threat Model or they will become a bottleneck for the development organization.
What if I told you, you can have your cake and eat it too. It is possible to scale your threat modeling program to *every* feature and you don't have to be a bottleneck to the development organization. What if I also told you that the Threat Models in this utopia are also of higher quality as well.
In this utopian world, Threat Modeling is no longer the Application Security team's responsibility. The responsibility now lies with the development teams. Self-serve Threat Modeling is the way of the future.
