This session introduces a DNS-based OSINT methodology that leverages large-scale TXT record analysis to uncover embedded service dependencies such as cloud platforms, SaaS integrations, and identity providers.By programmatically scanning DNS zones and integrating the technique into tools like Nuclei and OWASP Amass, this approach enables security teams to build detailed maps of organizational technology stacks and attack surfaces. A real-world case study from the Salesloft breach demonstrates how these signals translate into actionable intelligence for both offensive and defensive use cases.Rishi ( @rxerium ) is a London-based security researcher focused on vulnerability research, threat intelligence, and OSINT-driven attack surface discovery. He contributes to open-source security tooling, supports the UK OSINT community, and focuses on building scalable reconnaissance and detection methodologies.
