A collaboration of researchers from the University of Birmingham in the UK, the Graz University of Technology in Austria and KU Leuven in Belgium developed a new fault injection attack named Plundervolt that can endanger Intel SGX secrets, as well as likely to trigger memory safety errors in programs that do not have such bugs in their system. The technology Intel Software Guard Extensions (SGX) is present in modern Intel CPUs that enable users to set up so-called enclaves where the CPU encrypts part of the memory and does not allow any programs except those running inside the enclave to obtain it. This new technique can be used to overcome the security guarantees of the Intel SGX trusted execution environment, which is meant to defend cryptographic secrets and to isolate sensitive code execution in memory.
