Explore critical vulnerabilities in macOS location privacy through this 29-minute Black Hat conference talk that demonstrates how attackers can determine user locations without consent. Examine the macOS privacy framework with particular focus on location services as a distinct privacy subsystem, including how location permissions are stored and architectural weaknesses in the location database. Analyze the attack surface of location services, side-channel attacks, and techniques for obtaining both non-precise and precise location data through newly discovered vulnerabilities. Review Apple's security patches for these issues and discover how third-party macOS applications can willingly share location data with any requesting app, potentially eliminating the need for zero-day exploits. Learn actionable detection strategies for blue teams to mitigate location privacy risks and understand future research directions in macOS location security.
