Esto ya es tan habitual como un "culebrón"  :o

Nuevas vulnerabilidades (en realidad variantes de Spectre) puede extraer datos de los enclaves Intel SGX

Overview

SgxPectre Attacks resulted from a research project conducted by security researchers at The Ohio State University. The study systematically explores the insecurity of Intel SGX due to branch target injection attacks and micro-architectural side-channel attacks. The research is one of a series of research projects on SGX side channels in which OSU researchers have been involved.

Software Guard eXtensions (SGX) is a hardware extension available in recent Intel processors. SGX provides software applications shielded execution environments, called enclaves, to run private code and operate sensitive data, where both the code and data are isolated from the rest of the software systems. Even privileged software such as the operating systems and hypervisors are not allowed to directly inspect or manipulate the memory inside the enclaves. There are already commercial cloud platforms that utilize SGX to offer customers trustworthy computing environments (..)
