Researchers from the University of Birmingham in the UK, Graz University of Technology in Austria and KU Leuven in Belgium have developed a new attack tool that is capable of corrupting the integrity of Intel Software Guard Extensions (SGX) in Intel Core processors by controlling the voltage when executing enclave computations. Plundervolt works by created a low voltage in the CPU to create a fault. These faults, when predicted, can be manipulated to allow an attacker with root-level privileges in the infected system to leak secrets, including encryption keys.
