The Dark Overlord is considered to be one of the world’s most well-known hacking groups because of its unwillingness to discriminate in the selection of its victims. The group has made millions attacking and extorting hundreds of organizations, ranging from small medical facilities to mega fortune companies like Netflix and Disney. The group’s continued escalation of cyber terrorism and violence eventually led to the closure of over 30 school districts in the U.S. for an entire week, and the publishing of a stolen insurance video of a man’s death in a construction site accident. Based on my book, “Hunting Cyber Criminals,” this talk will present the investigative tools and techniques that led to the identification of the group’s core members.
