Detecting Dedicated Infrastructure

Detecting the bulletproof hostings that make up the dedicated infrastructure used by Phishing and Malware actors involves a variety of creative techniques. A lot of things have changed since the time of RBN (Russian business network): abused and compromised hosters, their services and DDoS protection help bad guys just as well as cybercrime fighters making exposure and indictment a hard job. In this session, we will detail our approach to uncovering such systems at scale based off global DNS data while explaining the underlying architecture of phishing campaigns which already made more than $50 million. We will show what it takes to go from detection of the phishing domain to cooperation with Law Enforcement and taking down infrastructure and actors behind cybercrime campaigns.
