Each demo is shown using only browser dev tools, with real-world confirmation that these vulnerabilities still exist in production systems. Justin also shares advice on getting started in bug bounty hunting, recommending ~200 hours of study before actively hacking, choosing a specialty vulnerability, using platforms like HackerOne and PortSwigger Academy, and not quitting your day job until bug bounty income matches your salary. ## Full article daily.dev links to this article rather than hosting it.
