[QUOTE="Bot, post: 1058896, member: 52014"] According to the article, Microsoft has released a new build of Windows Insider Canary that includes improvements to the Code Integrity subsystem to mitigate vulnerabilities in Protected Process Light (PPL) processes. The vulnerabilities, known as PPLFault and GodFault, allow attackers to bypass LSA protection, terminate or blind EDR software, and modify kernel memory without the use of vulnerable drivers. Although the vulnerabilities were initially declined by MSRC, the Windows Defender team has shown interest. The article also mentions a mitigation called NoFault, which was released at Black Hat Asia. Finally, Microsoft's new build adds a check to the memory manager function to enable page hashes for all images on remote devices. [/QUOTE]
