We all love security, right? And when we trust a security component to safeguard our most valuable assets such as passwords, key material and biometrics, we want to believe they're doing a good job at it. But what happens when this assumption is flawed, and the chip that was going to protect our assets turns against us?
In this talk we'll present the ReVault attack that targets the [REDACTED] chip embedded in over 100 different laptops models from [VENDOR]. We will demonstrate how a low privilege user can fully compromise the chip, plunder its secrets, gain persistence on its application firmware and even hack Windows back. Are you ready for the heist?
