c++ - 将文本复制到由 virtualalloc() 分配的内存

Question

这是我正在尝试进行恶意软件分析的代码示例。在 shellcodePayload 中，我可以存储汇编指令，甚至是可执行的有效载荷。但我想知道是否可以在本节中存储字母和数字。例如，我想添加一个文本字符串，如“HELLO WORLD”。可能吗？

#include <windows.h>
#include <stdio.h>
#include <stdlib.h>
#include <string.h>

int main(void) {
    
    void * alloc_mem;
    BOOL retval;
    HANDLE threadHandle;
    DWORD oldprotect = 0;

    unsigned char shellcodePayload[] = {
        0x90,       // NOP
        0x90,       // NOP
        0xcc,       // INT3
        0xc3        // RET
    };
    unsigned int lengthOfshellcodePayload = 4;
    
    alloc_mem = VirtualAlloc(0, lengthOfshellcodePayload, MEM_COMMIT | MEM_RESERVE, PAGE_READWRITE);
    printf("%-20s : 0x%-016p\n", "shellcodePayload addr", (void *)shellcodePayload);
    printf("%-20s : 0x%-016p\n", "alloc_mem addr", (void *)alloc_mem);

    RtlMoveMemory(alloc_mem, shellcodePayload, lengthOfshellcodePayload);
    
    retval = VirtualProtect(alloc_mem, lengthOfshellcodePayload, PAGE_EXECUTE_READ, &oldprotect);

    printf("\nPress Enter to Create Thread!\n");
    getchar();

    if ( retval != 0 ) {
            threadHandle = CreateThread(0, 0, (LPTHREAD_START_ROUTINE) alloc_mem, 0, 0, 0);
            WaitForSingleObject(threadHandle, -1);
    }

    return 0;
}
