DNS(Domain Name System) is the critical & ubiquitous fabric of the Internet and it is used for genuine reasons and also abused by bad actors for malicious purposes.

Statistically, based on a number of research papers, majority of the newly registered domains are used for malice (phishing, ransomware, malware etc).

Passive DNS technique provides an option to Security professionals( Incident Responders, SOC Analysts, Malware Researchers ) and Law enforcement to dive into mapping the DNS infrastructure of the bad actors and facilitate takedowns.

In this presentation, I will be introducing Passive DNS (briefly) and will be sharing two personal use cases of using Passive DNS to,
1. Uncover Godaddy Domain shadowing
2. Map DNS infrastructure of bad actors and report for takedown

Note - As a bonus for Star Wars fans, the talk has a few references to Droids :-)
