An undocumented feature in Intel CPUs allows attackers to manipulate the voltage of Intel CPUs to trigger computational faults in a controlled manner. This can be used to defeat the security guarantees of the Intel SGX trusted execution environment, which is meant to protect cryptographic secrets and to isolate sensitive code execution in memory. Researchers from the University of Birmingham in the UK, Graz University of Technology in Austria and KU Leuven in Belgium developed a new fault injection attack dubbed Plundervolt. The attack affects all SGX-enabled Intel Core processors starting with the Skylake generation.”]
