Hyper_rw

This document introduces the GuestMemory virtual memory access class, based on noahware/hyper-reV, as well as four kernel utility functions used for locating the target process CR3, EPROCESS, PEB, and module base addresses.

This project depends on a specific Windows version (Windows 11 25H2). If the version does not match, this project will not run; please modify the Offsets in GetM &PsActiveProcessHead offset:0xF05790 in Hyper_rw.cpp.

1. Core Utility Functions

These functions rely on PsActiveProcessHead to locate key process structures from the kernel side.

GetProcessCr3

Parameters: target_pid, ps_active_process_head
Returns: CR3 (DirectoryTableBase)
Traverses ActiveProcessLinks and returns the page table base address for the process based on the PID.

FindProcessEProcessBase

Parameters: Same as above
Returns: EPROCESS kernel virtual address
Suitable for use when accessing fields like Token, HandleTable, etc.

FindPebByCr3_Raw

Parameters: target_cr3, ps_active_process_head
Returns: PEB user-mode virtual address
Reverse lookups EPROCESS via CR3, then reads the Peb field; does not rely on PID.

GetModuleBase_Raw

Parameters: target_cr3, peb_address, module_name
Returns: DllBase
Traverses the PEB Ldr module list to find the target DLL.

2. GuestMemory

GuestMemory encapsulates VA→PA translation and cross-page handling, serving as the primary interface for accessing target process virtual memory from user mode.

Construction

GuestMemory mem(target_cr3);  // 绑定页表

2. ReadValue / WriteValue

int hp = 0;
mem.ReadValue<int>(0x7FF70010, hp);

3. Call Flow Overview

Get PsActiveProcessHead

Get target CR3

Initialize GuestMemory

Find PEB

Find target DLL

Use GuestMemory to read/write target address
