This Black Hat conference talk explores the boot chain vulnerabilities in Samsung Galaxy A series devices with Mediatek chips. Learn how security researchers initially investigated Android File-Based encryption to exploit boot ROM vulnerabilities for bypassing secure boot and retrieving credentials for brute force attacks. The presentation then delves deeper into the Little Kernel bootloader (LK/BL3-3) component that appears later in the boot process. Presented by Maxime Rossi Bellom and Raphael Neveu, with contributions from Damiano Melotti and Gabrielle Viala, this 39-minute technical analysis provides valuable insights for security professionals interested in mobile device boot chain security.
