Gerben Janssen van Doorn, a 21-year-old ethical hacker from The Netherlands, has rapidly ascended the ranks in the security research community, becoming one of the top contributors on HackerOne's leaderboard and a valued member of the Detectify Crowdsource network. His journey into ethical hacking began at age 15 when he automated a tedious task at a part-time job using PHP, sparking his interest in web vulnerabilities. Over the years, he has honed his skills, focusing on creative approaches to finding high-severity vulnerabilities, especially in main domains rather than subdomains, using tools like LinkFinder and various search engines for analysis. Gerben emphasizes the importance of understanding XSS for budding ethical hackers and appreciates the collaborative nature of the white hat hacker community, which is united by a shared belief in the bug bounty industry's potential. He values bug bounty programs that are fair and focuses on those that align with his interests, while also acknowledging the role of community collaboration in tackling complex security issues. Despite his current high ranking, his future plans remain open as he finishes his master's degree in organizational design and development, contemplating either a full-time commitment to bug hunting or a position within an organization.
