Episode 26: Client-side Quirks & Browser Hacks

Critical Thinking - Bug Bounty Podcast

In this episode of Critical Thinking - Bug Bounty Podcast, we're back with Joel, fresh (haha) off of back-to-back live hack events in London and Seoul. We start with his recap of the events, and the different vibes of each LHE, then we dive into the technical thick of it, and talk web browsers, XSS vectors, new tools, CVSS 4, and much more than we can fit in this character limit. Just trust us when we say you don’t want to miss it!
