Dive into Apple IO80211FamilyV2

Дата: 26.02.2021. Автор: CISO CLUB. Категории: Подкасты и видео по информационной безопасности

Starting from macOS Catalina Beta, Apple refactored the architecture of the 80211 Wi-Fi client drivers and renamed the new generation design to IO80211FamilyV2. Compared with IO80211Family (V1), modules such as Version 2 and AppleBCMWLANCore integrate the original AirPortBrcm series drivers and further expand features such as Sidecar and Skywalk. These latest changes provide better support and protection for communication and data sharing between devices. Of course, we should also realize that new features are always accompanied by new vulnerabilities and potential risks of being attacked.
