Presented at BSidesLV 2019, Aug. 7, 2019, 6 p.m. (55 minutes)

Do you want to know how you can exploit DNS rebinding 10x faster, bypass prevention mechanisms, interactively browse the victim's internal network, and automate the whole process during your next red team exercise? This talk will teach you how and give you an easy-to-use tool to do it. First, we will cover in detail the subtleties that make DNS rebinding attacks more effective in practice, including techniques and operational conditions that make it faster and more reliable. We'll also explain how to bypass commonly recommended security controls, dispelling attack and defense misconceptions that have been disseminated in blogs and social media posts. This talk will include a number of demos using Singularity, our open source DNS rebinding attack framework that includes all the parts you need to get started pwning today, including: - Remote code execution and exfiltration payloads for common dev tools and software - Practical scanning and automation techniques to maximize the chance of controlling targeted services We'll also show an interesting post-exploitation technique that allows browsing a victim browser network environment without the use of HTTP proxies.
