We are pleased to announce that the researchers of Exodus Intelligence will be providing publicly available training in person on November 14 2023 in London, England.

This 4 day course is designed to provide students with both an overview of the current state of the browser attack surface and an in-depth understanding of advanced vulnerability and exploitation topics. Attendees will be immersed in hands-on exercises that impart valuable skills including static and dynamic reverse engineering, zero-day vulnerability discovery, and advanced exploitation of widely deployed browsers such as Google Chrome and Apple Safari.

Taught by Senior members of the Exodus Intelligence Browser Research Team, this course provides students with direct access to our renowned professionals in a setting conducive to individual interactions.


Hands on with privilege escalation techniques within the JavaScript implementations, JIT optimizers and rendering components.
