Clocks Have Ears - Timing and Browser-Based Local Network Port Scanner

Learn about an innovative browser-based local network port scanning technique presented at DEF CON 31 that leverages timing attacks to detect open ports without traditional scanning methods. Explore how this unique approach uses browser timing measurements to identify network services, understand the technical implementation details, and discover the security implications of this scanning methodology. Dive into the research findings presented by Dongsung Kim that demonstrate how browsers can be used as unconventional tools for network reconnaissance, highlighting potential vulnerabilities in local network security.
