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
April 10, 2024 at 01:24PM Researchers have developed the first native Spectre v2 exploit, affecting Linux systems on modern Intel processors. The discovery highlights the ongoing challenge of balancing performance optimization with security. Spectre V2 leverages speculative execution, leaving traces of sensitive data in CPU caches, and introduces security risks. Various entities are responding with … Read more
April 10, 2024 at 10:25AM VUSec cybersecurity group at VU Amsterdam university revealed a new form of the Spectre v2 attack targeting Intel processors. Named Branch History Injection (BHI), it bypasses hardware mitigations and can leak kernel memory on the latest Intel CPUs. Intel updated guidance on mitigations and plans to address BHI in future … Read more
