Account takeovers (ATO) remain one of the biggest threats to marketplace platforms, with fraudsters using phishing, credential stuffing, and social engineering. This session covers Grubhub’s approach to securing diner, driver, and merchant accounts through login monitoring, anomaly detection, and multi-layered authentication. We’ll discuss real-world case studies of ATO attacks and share best practices for balancing friction and security. Attendees will learn how to proactively prevent takeovers and mitigate fraud losses.

This workshop will explore how AI can enhance trust and safety for digital platforms. The first half will focus on industry challenges and innovations, featuring insights from OpenSea. The second half will be a hands-on lab where attendees will use AI to detect high-risk incidents from real-world datasets (e.g., customer complaints about severe safety issues). Participants will learn practical prompt engineering techniques to classify and flag risk signals efficiently. The goal is to provide a tangible demonstration of AI’s role in trust and safety decision-making.

This session will explore the critical role of deepfake detection in safeguarding trust and safety for digital platforms and marketplaces. Attendees will gain insights into cutting-edge AI technologies used to identify and analyze deepfakes in real-time, ensuring content authenticity and minimizing reputational risks. The discussion will cover evolving deepfake trends, their implications for platforms, and best practices for proactive risk management. Key takeaways include actionable strategies for implementing AI-driven solutions, building user trust, and fostering safer digital environments. Join us to learn how innovative tools like Contrails.ai are reshaping the fight against misinformation and media manipulation.
