This kind of discovery demonstrates why ongoing security research is so important, as even a major company like Intel can be subject to unseen vulnerabilities.
Technical Paper (PDF): https://arxiv.org/pdf/1702.08719.pdfIntended to help users keep their systems safe and secure, Intel Software Guard Extensions is a set of CPU instructions that can make particular portions of code and data private. However, a new paper suggests that SGX could in fact be used to facilitate a malicious attack.
Samuel Weiser and four collaborators from the Graz University of Technology in Austria have published research that demonstrates how SGX can be used to conceal a piece of malware. Within minutes, this technique was used to gain access to RSA keys hidden in SGX enclaves.
