The goal is to create a driver that bypasses user-mode access restrictions on protected processes (like CSRSS) to enumerate loaded DLLs. Covers Windows driver fundamentals: kernel vs user mode, IRP (I/O Request Packets), device objects, symbolic links, dispatch routines (create/close/device control), and the WDM driver model. Demonstrates writing DriverEntry, implementing DeviceIoControl handling, using ZwOpenProcess from kernel mode to obtain unrestricted process handles, and installing/loading the driver via SC commands on a VM. ## Full article daily.dev links to this article rather than hosting it.
