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
May 8, 2024 at 11:07AM Researchers discovered two new attack methods targeting high-performance Intel CPUs, collectively called Pathfinder. These attacks exploit the branch predictor to manipulate program control flow and execute Spectre-style attacks, potentially exposing confidential data, including AES encryption keys and secret images. Intel stated that existing mitigations for Spectre v1 help protect against … Read more
April 10, 2024 at 04:32PM VU Amsterdam academics discovered that Intel CPU cores are still vulnerable to Spectre attacks, despite mitigations. They created InSpectre Gadget, which can find code snippets to bypass protections, even on chips with Spectre defenses. The tool helped develop Native Branch History Injection exploit, allowing access to sensitive data. AMD and … Read more
November 10, 2023 at 09:36AM A class action lawsuit has been filed against Intel over its handling of speculative execution vulnerabilities, specifically the “Downfall” attack. Plaintiffs claim that Intel CPUs are defective, leaving them vulnerable to cyberattacks or with significantly slower performance due to vulnerability fixes. The complaint accuses Intel of selling flawed CPUs despite … Read more
