You will be registering your interest in a online, live offering of Browser (JS Engine) Exploitation. Dates TBA, we will notify you when the course has dates available.

This 3-day course will give students a zero to hero in-depth examination of techniques to exploit JavaScript engine memory corruption bugs in the Firefox and Chrome web browsers. Spidermonkey and V8 will be the targets for exploitation. Spidermonkey is the JS engine in Firefox and V8 is the JS engine in Chrome. The OS environment for the course is Linux. However, the exploitation concepts and techniques presented will work on other platforms.  

Course Objectives

To be able to gain code execution in Firefox (Spidermonkey) and Chrome (V8) given a JS engine memory corruption bug. Sandbox escapes will not be covered in this course.

Duration and Schedule

3 Days, 9am - 5pm

Training Outcomes

  • Demonstrate understanding of JS engine internals
  • Demonstrate building exploitation primitives
  • Demonstrate code execution in modern JS engines and web browsers
