Previous work such as Plundervolt has shown that software-based undervolting can induce faults into Intel SGX enclaves and break their security guarantees. However, Intel has addressed this issue with microcode updates.
We later discovered that there is a physical connection on the motherboard which allows us to control the voltage and conduct fault injection. In this talk, we will present a low-cost device: Voltpillager, which use this physical connection to break the guarantees provided by SGX again.
