July 3, 2024 at 06:24AM Researchers at the University of California San Diego have detailed a new attack method, Indirector, targeting high-end Intel CPUs. The method exploits the Indirect Branch Predictor and Branch Target Buffer, allowing attackers to bypass existing defenses and compromise CPU security. Intel maintains that previously issued mitigations should effectively address the … Read more
July 2, 2024 at 07:07AM Modern Intel CPUs like Raptor Lake and Alder Lake are vulnerable to a new side-channel attack named “Indirector.” The attack exploits weaknesses in Indirect Branch Predictor (IBP) and Branch Target Buffer (BTB) to leak sensitive information. Mitigations include using Indirect Branch Predictor Barrier (IBPB) more aggressively and hardening the Branch … Read more
December 7, 2023 at 07:48AM Upcoming CPUs from Intel, AMD, and Arm may be susceptible to a new type of ‘SLAM’ attack despite planned security enhancements, researchers warn. Key Takeaways from Meeting: – Major CPU vendors, which include Intel, AMD, and Arm, are planning to integrate new security features into their future products. – There … Read more
December 6, 2023 at 07:57PM Researchers at VUSec discovered “SLAM,” a side-channel attack exploiting memory features in future CPUs from Intel, AMD, and Arm, to leak sensitive information like root password hashes. Despite the intended security improvements, these features inadvertently enable SLAM by not checking address canonicality, creating micro-architectural race conditions. Existing defenses are deemed … Read more
