OWASP Ottawa: "Blackout at Scale: Iran's Internet Shutdown"
–
· 150, 150 Louis-Pasteur Private, Ottawa, ON K1N 9B4, Canada
The event features a technical talk by Ali Sadeghi Jahromi exploring the Internet disruptions in Iran during early 2026. This presentation utilizes a multi-plane measurement approach that combines passive Internet-wide scanning, active probing, and BGP routing analysis to examine how shutdowns were enforced through centralized forwarding-plane null-routing. The analysis covers the collapse of host populations, the structural behavior of specific network exemptions such as academic and CDN infrastructure, and the limitations of individual measurement perspectives in detecting large-scale Internet control.
