LINE Launches Public Bug Bounty Program: Q&A with Security Engineer Robin Lunde

LINE announced the migration of its long-running bug bounty program to HackerOne to increase global visibility and participation. The interview outlines program scope (LINE apps across platforms and select domains), in-scope and out-of-scope assets, the types of vulnerabilities the team values (RCE, SSRF, SQLi, logic bugs, PII disclosures, privilege escalations), how reports are handled, and guidance for researchers on reporting quality and impact assessment.
