"About three months ago I started the Browser Exploit Design training of Zero Day Engineering.

A very interesting self-paced course where a combination of browser internals, realistic exploit development workflows and hands-on exercises based on modern browser 0-days is discussed. It includes topics such as DOM use-after-free bugs, JavaScript engine type confusion and sandbox escapes in Chrome, Firefox and Safari/WebKit.

It is without a doubt the most challenging course I have followed so far in the field of (browser) exploitation. And I still have a lot to learn in this. But much more insight into how browsers work and how browser exploits are done in practice. To be continued." – Ian van der Wurff, Hacker || OSCE3 | OSCP
