Dr Miah Hammond-Errey is joined by Dr Johnny Ryan, Director of Enforce at the Irish Council for Civil Liberties and a leading authority on surveillance, data rights, and privacy. Drawing on his extensive experience in the ad tech industry and digital rights advocacy, Dr Ryan explains how real-time bidding (RTB)—the backbone of online advertising—routinely exposes Australians’ sensitive personal information to hundreds of companies. The conversation unpacks the findings of "Australia’s Hidden Security Crisis," a report revealing how RTB enables the unchecked flow of data about individuals, their families, and even high-level government and defence personnel to foreign jurisdictions, including China and Russia. 

Listeners learn how this invisible system works–and how extensive it is–why consent pop-ups do little to protect privacy, and how data categories traded in these auctions can include everything from health and finances to mental state and personal relationships. We explore the current challenges for legislators and enforcement agencies as well as the impact of algorithms on influence and interference. The discussion highlights the national security risks posed by this pervasive form of data collection and sale, including the potential for blackmail, espionage, and foreign surveillance. The episode is a must-listen for anyone interested in the intersection of technology, privacy, data and security.
