使用系统提供的API PsGetCurrentProcess()可以获取当前进程的EPROCESS结构的基地址。
使用基地址+偏移的方式可以获取到相关的进程信息。

#include <ntifs.h>
 
NTSTATUS DriverUn(PDRIVER_OBJECT obj)
{
    UNREFERENCED_PARAMETER(obj);
    return STATUS_SUCCESS;
}
 
 
NTSTATUS DriverEntry(PDRIVER_OBJECT obj, UNICODE_STRING64 regPath)
{
    UNREFERENCED_PARAMETER(regPath);
    obj->DriverUnload = (PDRIVER_UNLOAD)DriverUn;
 
    //遍历进程
    DWORD64 pEprocess = PsGetCurrentProcess();
    // 当前进程在双向链表中的位置 就是这个链表把系统中的所有进程都给串起来了
    // 所以根据循环这个双向链表 就可以找到系统中所有的进程
    PLIST_ENTRY List = (PLIST_ENTRY*)(pEprocess + 0x448);
    DbgPrintEx(DPFLTR_IHVDRIVER_ID, DPFLTR_ERROR_LEVEL, "pPeb=%llx\n", pEprocess);
    DbgBreakPoint();
    PLIST_ENTRY List1 = List;
     
    while (List1->Flink!=List)
    {
        // 双向链表的地址-偏移 得到eprocess的基地址
        DWORD64 eProcess = ((DWORD64)List1 - 0x448);
        // 进程ID的偏移
        DWORD64 pId = *(PDWORD64)(eProcess + 0x440);
        // 进程名称的偏移
        DWORD64 ulProcessNmae = (DWORD64)(eProcess + 0x5a8);
        DbgPrintEx(DPFLTR_IHVDRIVER_ID, DPFLTR_ERROR_LEVEL, "PID=%d\n", pId);
        DbgPrintEx(DPFLTR_IHVDRIVER_ID, DPFLTR_ERROR_LEVEL, "Name=%s\n", ulProcessNmae);
        List1 = List1->Flink;
    }
    return STATUS_SUCCESS;
