Intel CPUs Face Spectre-Like ‘Indirector’ Attack That Leaks Data

by

July 3, 2024 at 10:33AM Researchers at UCSD have developed a new method, called “Indirector,” to execute Spectre-like side channel attacks on high-end Intel CPUs. This technique exploits the speculative execution feature to redirect a program’s control flow, potentially leaking sensitive data. The attack works on various generations of Intel CPUs and poses challenges for … Read more

Latest Intel CPUs impacted by new Indirector side-channel attack

by

July 1, 2024 at 01:40PM New BTI attack called Indirector targets modern Intel CPUs, specifically Raptor Lake and Alder Lake generations. It exploits flaws in Indirect Branch Predictor and Branch Target Buffer to manipulate speculative execution, enabling data extraction. Researchers at UC San Diego discovered and presented the attack, proposing mitigations like IBPB and BPU … Read more
