How do we stop scammers who move faster than the law? In this episode, we go behind the scenes of the Global Signal Exchange (GSE) to reveal how a billion-signal database is revolutionising the fight against global fraud.

Join Emily, Lucien, and Mark from Oxford Information Labs as they discuss the technical architecture and real-world impact of the GSE. Discover how a landmark "Malvertising" pilot between Google and Amazon proved that even the world’s largest platforms have blind spots that only collaborative signal sharing can fix. We dive into the "Big Tech" partnerships, the use of AI and LLMs for threat classification, and why "making it a sport" through league tables is encouraging providers to clean up the internet's supply chain.
