In November 2010, the press reported that the rootkit had evolved to the point that it was bypassing the mandatory kernel-mode driver signing requirement of 64-bit editions of Windows 7. It did this by subverting the master boot record, [8] which made it particularly resistant on all systems to detection and removal by anti-virus software.
WrmOS [39] is a real-time operating system based on L4 microkernel. It has own implementations of kernel, standard libraries, and network stack, supporting ARM, SPARC, x86, and x86-64 architectures. There is the paravirtualized Linux kernel (w4linux [40]) working on WrmOS. Helios is a microkernel inspired by seL4. [41]
The suddenly-cozy relationship between Linux and Windows is taking another step forward, as Microsoft announced in a blog post that it's going to ship a full Linux kernel in Windows 10. It will ...
A rootkit can modify data structures in the Windows kernel using a method known as direct kernel object manipulation (DKOM). [33] This method can be used to hide processes. A kernel mode rootkit can also hook the System Service Descriptor Table (SSDT), or modify the gates between user mode and kernel mode, in order to cloak itself. [4]
User-Mode Driver Framework v2, for writing user-mode drivers with syntactic parity to KMDF WDF also includes a set of static verification tools for use by driver writers. These tools examine driver code for common errors and/or simulate the code of a driver in order to identify problems that are both difficult to detect and difficult to test for.
I/O request packets (IRPs) are kernel mode structures that are used by Windows Driver Model (WDM) and Windows NT device drivers to communicate with each other and with the operating system. They are data structures that describe I/O requests, and can be equally well thought of as "I/O request descriptors" or similar.
With the Windows Drivers Model (WDM) for devices Microsoft implements an approach to kernel mode drivers that is unique to Windows operating systems.WDM implements a layered architecture for device drivers, and every device of a computer is served by a stack of drivers.
The Native API is a lightweight application programming interface (API) used by Windows NT's kernel and user mode applications. This API is used in the early stages of Windows NT startup process, when other components and APIs are still unavailable.
