Overview
Explore the world of next-generation mobile rootkits in this Black Hat EU 2013 conference talk. Delve into the use of hardware security features in last-generation ARM processors to create and conceal rootkits that are virtually undetectable by operating systems. Learn about TrustZone technology, Trusted Execution Environments, and their applications in mobile security. Discover the attacker model, memory management in TrustZone, and the boot process for these advanced rootkits. Gain insights into hardware support, testing environments, and rootkit scheduling techniques. Examine IRQ interception, Secure World setup, and communication methods. Understand the challenges of interoperability and detection methods for these sophisticated mobile threats. Benefit from the speaker's practical experience in developing and hiding an actual rootkit using these cutting-edge techniques.
