SpectreRSB – new Spectre CPU side-channel attack using the Return Stack Buffer

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 […]

How to steal encryption keys from the air through a PC’s noises

A group of Israeli researchers demonstrated how to steal RSA encryption keys through a PC’s noises during cryptographic operations. If you think that air-gapped networks are totally secure you are wrong, in the past, many research teams have devised methods to steal data from computers disconnected from the Internet. They demonstrated that it is possible […]
