Manipulating processes in the kernelIn the kernel operation process, I believe is a lot of WINDOWS kernel programming interested in the first learning point of knowledge of a friend. But here, I want to let everyone down, the operation process in the kernel is nothing special, in terms of the standard method, still call the process-related NATIVE API (of course, this article refers to the process operation, also includes the operation of the thread and DLL module). This article consists of 10 pa

When injecting drivers, we must be aware of the current IRQL. IRQL is the current hardware priority of a specified kernel program. Many kernel programs request IRQLPassive (0 ). If it runs at dispatch (2) level (used for program scheduling and latency Process calling), IRQL must be dropped to passive.This is just a simp

T = 80971When a program is debugged by the ring3 debugger, many debugging features can be detected. This forum also has a special post for details, however, there is a very fundamental identifier ring3 that few people can detect, namely _ eprocess. debugport. Debugport is very important for the ring3 debugger. Without its

The real reason for the increase in price increases in addition to the rising price of follow-up funds in a timely manner, the existence and gush of large profit disk is another imp

When a process creates a thread, the system calls our thread callback function in the context of the process, therefore, we can use the psgetcurrentprocessid function to obtain the process number. Get the thread number through psgetcurrentthreadid. Note that this thread is not the thread to be created, but the thread that contains the code for creating the thread.

Hidden process and recovery (with code) and Process Code First, we know that the process body EPROCESS is maintained by the system in a two-way linked list LIST_ENTRY. Therefore, we only need to remove the process EPROCESS from this linked list to implement process hiding, of course, this can only hide the Process Manager and zwQuerySystemInformation. The process hidden by the broken chain can still be foun

Pspcidtable holds all process and thread objects in the system, which are either the process ID (PID) or the thread ID (TID). Let's look at the handle_table structure in WinDbg first:You can see that the content stored in address 0x83f41bc4 is 0x 8da010a8, which is the structure of the system's _handle_table.Well, now WinDbg is getting handle_table structure, or code implementation.
