Microsoft uses AI to find flaws in GRUB2, U-Boot, Barebox bootloaders

Microsoft used its AI-powered Security Copilot to discover 20 previously unknown vulnerabilities in the GRUB2, U-Boot, and Barebox open-source bootloaders.

One Book To Boot Them All

Somewhere in the universe, there’s a place that lists every x86 operating system from scratch. Not just some bootloaders, or just a kernel stub, but documentation to build a fully functional, interrupt-handling, multitasking-capable OS. [Erik Helin and Adam Renberg] did just that by documenting every step in The Little Book About OS Development. This is not your typical dry academic textbook. It’s a hands-on, step-by-step guide aimed at hackers,…

Microsoft’s AI Finds Security Flaws in Bootloaders for Linux Systems

Microsoft Security Copilot, an artificial intelligence (AI) cybersecurity tool, was used to discover several previously unknown vulnerabilities in open-source bootloaders. The Redmond-based tech giant recently revealed a list of the security flaws discovered in three commonly used bootloaders. One of the bootloaders is the default for many Linux-based systems, while the other two are typically used for embedded systems and Internet of Things (Io…

Microsoft security experts have discovered a number of previously undocumented vulnerabilities in the widely used open source bootloaders GRUB2, submarine and barebox. This was possible by helping yourself with an AI. (Read more)

Microsoft Security Copilot Uncovers New Vulnerabilities in Open-Source Bootloaders

Microsoft’s Security Copilot, an AI-powered security analysis tool, has uncovered several vulnerabilities within widely used open-source bootloaders, including GRUB2, U-Boot, and Barebox. These flaws, if exploited, could allow attackers to execute arbitrary code, potentially bypassing security measures like Secure Boot. The company has disclosed the findings in a blog post. The vulnerabilities were primarily found in the filesystem parsing compo…

The evidence with Microsoft Security Copilot, the IA cybersecurity assistant, who has discovered for himself some 20 critical vulnerabilities in the GRUB2 bootloaders, U-Boot and Barebox. If you are using Linux/UNIX or embedded systems, this news is about you... These new vulnerabilities allow you to bypass Secure Boot, install undetectable bootkits and stay in place after the system is reset. In short, your system can be completely compromised,…
