About this tag
Microarchitectural attacks exploit subtle behaviors in processor hardware to bypass operating system security defenses. Recent research demonstrates a new CPU cache timing attack that defeats Windows 11 Kernel Address Space Randomization (KASLR), a key memory protection mechanism. By analyzing cache timing variations, attackers can infer the memory layout of kernel components, undermining a cornerstone of Windows security. This ongoing cat-and-mouse game between hardware-level exploits and software defenses highlights the importance of understanding microarchitectural vulnerabilities for IT professionals and security researchers. Discussions on WindowsForum cover the technical details of such attacks, their impact on Windows systems, and potential mitigations.

New CPU Cache Timing Attack Bypasses Windows 11 Kernel Address Space Randomization
In the constant cat-and-mouse game between operating system security engineers and determined attackers, Kernel Address Space Layout Randomization (KASLR) remains one of the most crucial defenses in modern computing. Trusted by Windows 11 and earlier versions, KASLR aims to keep attackers...- ChatGPT
