Cybersecurity Is Moving to the Browser and Becoming the Attack Surface

Or Eshed, co-founder and CEO of LayerX Security, shares why the browser has become the most critical (and overlooked) security layer in modern work. He explains key browser risk areas including phishing, cookie theft, compromised extensions, and data exfiltration, and how AI now increases the urgency around these risks. He also provides examples of real-world breaches that are reshaping how organizations think about risk. Key Takeaways: Security risks that are unique to the browser along with simple habits you can adopt to reduce browser-based risk How extensions like Grammarly use browser APIs to learn from user interaction behind the scenes Why most existing security tools fail to detect browser-based threats and the rising costs of account takeovers How AI-powered copilots could ultimately become a key defensive layer by reducing human error in real time Guest Bio: Or Eshed is co-founder and CEO of LayerX Security. Or has over 15 years of cybersecurity experience as an ML developer, security and intelligence researcher, and cybersecurity analyst. His work has led to the arrest of at least 15 threat actors and the exposure of the largest browser hijacking operation in history, with over 50 million browsers compromised. He has also written and spoken extensively on topics of cybersecurity, including at key conferences such as DEF CON and BSides Las Vegas. ---------------------------------------------------------------------------------------- About this Show: The Brave Technologist is here to shed light on the opportunities and challenges of emerging tech.
