In Singapore, OKX and HackerOne brought an elite team of security researchers together for a live hacking event focused on one thing: building trust through real-time collaboration. This was security in action—fast-paced, transparent, and deeply human. Researchers tested live systems. Teams worked side by side. Vulnerabilities were uncovered and addressed when it mattered most. When trust is built in real time, everyone wins. #H165 #TogetherWeHitHarder
