Five years after the Spectre and Meltdown CPU attacks, researchers have discovered a new variant called Indirector that exploits low-level features of Intel CPUs to break security boundaries and leak protected data. This technique, developed by researchers at the University of California, San Diego, targets the indirect branch predictor (IBP) and branch target buffer (BTB) … Read more
A team of researchers at the University of California, San Diego have identified a new side-channel vulnerability in Intel processors which could potentially lead to the leakage of sensitive data. This vulnerability, present in the Indirect Branch Predictor (IPB) and Branch Target Buffer (BTB) components of certain high-end Intel CPUs, could be exploited by attackers … Read more
A new high-precision Branch Target Injection (BTI) attack called ‘Indirector’ has been discovered by researchers at the University of California, San Diego. This attack targets flaws in the Indirect Branch Predictor (IBP) and Branch Target Buffer (BTB) found in modern Intel processors, specifically in the Raptor Lake and Alder Lake generations. Indirector manipulates speculative execution … Read more
