(Best) Practice Makes Perfect

HackerOne’s Chief Hacking Officer presents six real mediation cases from the platform that illustrate best practices for handling vulnerability reports, covering issues such as undisclosed subdomains leaking credentials, third‑party component flaws, safely testable DoS/cache poisoning, severity misclassification, scope transparency, and coordinated vulnerability disclosure; each case describes remediation steps, reward decisions, and how lessons were folded into policy and triage improvements to protect both hackers and customers.
