Researchers from the University of California, Riverside (UCR) have devised a new Spectre CPU side-channel attack called SpectreRSB. SpectreRSB leverage the speculative execution technique that is implemented by most modern CPUs to optimize performance. Differently, from other Spectre attacks, SpectreRSB recovers data from the speculative execution process by targeting the Return Stack Buffer (RSB). “rather than exploiting the … Continue reading SpectreRSB – new Spectre CPU side-channel attack using the Return Stack Buffer
