Hacking Browsers: The Easy Way
2026-03-13 , Main Stage

This year I found 5 vulnerabilities in browsers (3x Google Chrome, 1x Mozilla Firefox, 1x OBS Browser). One of the bugs allowed me, with minimal user-interaction, to steal private GitHub repositories from victims. From these vulnerabilities I expanded my research into vulnerabilities in LastPass, KeePass, XMind, Evernote.


When you think of browser vulnerabilities, you always think of insane V8 exploits that require crazy hacking skills, but with this talk I want to show that there are plenty of logic vulnerabilities present in major products that can be found with just a little creativity! Let's dive into these bugs together!

Hi! I’m Robbe Van Roey 👋

I’m a hacker. I like breaking stuff. I’m a penetration tester at Toreon, I’ve worked for a bug bounty company, and I’ve found 35+ CVEs. I love hacking web apps, mobile applications, AI systems, and Active Directory.
I’m also a teacher. I teach developers about secure coding, I teach beginners about Red Teaming for Hack The Box and I’ve created a bunch of YouTube videos on my channel.

In the online realm, you may know me as PinkDraconian. Come up to me and say hi!

My life motto is “Hacking you so you don’t get hacked“ and I’d like to show you part of that ideology during my talk. See you there!
