CVE-2022-22616: A Deep Dive into the Discovery of a Safari Vulnerability
Gatekeeper is a security feature built into macOS that prevents the user from executing potentially malicious and/or unwanted software. It is designed to ensure that only trusted software launches on a user’s system by verifying notarization and code signing information.
A vulnerability existed in the Safari browser that allowed a specially crafted zip to bypass all checks performed by Gatekeeper. This allowed for the execution of an application that was completely unsigned and un-notarized. Join us on this journey through macOS internals and research.
