Closer to 0-day
Emil Trägårdh
Security Fest 2025 · Day 1 · Main Stage
In this compelling talk at Security Fest, Emil Trägårdh, a Swedish ethical hacker, challenges a statement he made in a previous year: that **n-days** (vulnerabilities for which a patch exists) are as close to **zero-days** (vulnerabilities with no public patch or disclosure) as one can get without being the original researcher. This presentation systematically deconstructs that premise, demonstrating advanced techniques that allow security professionals to inch significantly closer to the zero-day frontier, even discovering and exploiting vulnerabilities before a public patch is available or widely acknowledged.
