Mikhail Klyuchnikov, known in the bug hunting community as n1, shares his decade-long experience at Positive Technologies leading a team focused on software security analysis. The team specializes in discovering new zero-day vulnerabilities while also reproducing known 1-day issues to support penetration testing engagements. Klyuchnikov is also a member of the PT SWARM team, which regularly publishes technical articles, tips, and timely vulnerability breakdowns. With extensive participation in international bug bounty platforms and the Russian Standoff Bug Bounty program, he aims to explain the practical role of 1-day vulnerabilities for newcomers entering bug bounty hunting. The article provides foundational knowledge on how security researchers leverage publicly disclosed vulnerabilities in real-world testing scenarios.
