🦠 Understanding Bootkits: A Deep Dive into Malware Mechanics. Bootkits are sophisticated malware that infects a system during the boot process, allowing them to manipulate the Windows kernel before the operating system fully loads. This article explains the mechanics of bootkits, focusing on how they hook into the bootloader via the UEFI (Unified Extensible Firmware Interface). The authors detail their process of gaining control during boot, including hooking the ExitBootServices function and patching the kernel to execute custom code. They emphasize the stealthy nature of bootkits, which makes them challenging for antivirus software to detect, and highlight the importance of security measures like Secure Boot to mitigate such threats. The article concludes with a demonstration of their bootkit’s functionality.
