In this episode, we explore what makes zero-days so dangerous, how they are discovered and weaponized, and the typical lifecycle from discovery to disclosure (or exploitation). Zero-days are often used by nation-state actors or advanced persistent threats (APTs) to quietly infiltrate targets, and may be sold on dark web markets for high prices. We examine real-world examples of zero-day attacks and how organizations can implement behavioral analysis, endpoint detection and response (EDR), and network segmentation to detect or limit damage. While zero-days can’t be predicted or patched in advance, you can reduce their impact by preparing for the unknown—through defense-in-depth, threat hunting, and layered detection. In a world where some attackers are always one step ahead, readiness becomes your strongest tool.","thumbnail_url":"https://img.transistorcdn.com/vNFnJKBJwlFw26pFcqayAo74th9ze-Ew75JoaFl1C0Q/rs:fill:0:0:1/w:400/h:400/q:60/mb:500000/aHR0cHM6Ly9pbWct/dXBsb2FkLXByb2R1/Y3Rpb24udHJhbnNp/c3Rvci5mbS80ZGRi/OTllZDNhNTJmMDQz/MTVmZTFjODllMTkw/MmU1Ni5wbmc.webp","thumbnail_width":300,"thumbnail_height":300}
