原始函数是这样的

[cpp] view plain copy

 

 

1. kernel32!CreateProcessInternalW:  
2. 00000000`7738e750 4c8bdc          mov     r11,rsp  
3. 00000000`7738e753 53              push    rbx  
4. 00000000`7738e754 56              push    rsi  
5. 00000000`7738e755 57              push    rdi  
6. 00000000`7738e756 4154            push    r12  
7. 00000000`7738e758 4155            push    r13  
8. 00000000`7738e75a 4156            push    r14  
9. 00000000`7738e75c 4157            push    r15  
10. 00000000`7738e75e 4881ec400b0000  sub     rsp,0B40h  
11. 00000000`7738e765 488b0564cc0e00  mov     rax,qword ptr [kernel32!local_unwind+0x606b1 (00000000`7747b3d0)]  

跟32位一样,在函数入口写入跳转指令,跟32不一样的是,不能再用之前的E9 xx xx xx xx这样的指令了,E9不支持64位地址跳转,最大只能支持到32位,

直接用E9大部分情况下会出错.所以我们换一种方法.

[cpp] view plain copy

 

 

1. mov rax,0x1122334455667788  
2. jmp rax  

机器码是48 b8 8877665544332211 ffe0总共占了12个字节,不是我们之前用E9跳转的5字节了.

最前面的48叫REX Prefix,大家可以GOOGLE下,4是固定的,8表示使用64位寄存器.

如果没有前面的48就变成了mov eax, 0x1122334455667788了,使用32位寄存器.

我们需要把函数前面12字节改成跳转指令,正好

[cpp] view plain copy

 

 

1. 00000000`7738e750 4c8bdc          mov     r11,rsp  
2. 00000000`7738e753 53              push    rbx  
3. 00000000`7738e754 56              push    rsi  
4. 00000000`7738e755 57              push    rdi  
5. 00000000`7738e756 4154            push    r12  
6. 00000000`7738e758 4155            push    r13  
7. 00000000`7738e75a 4156            push    r14  

这12个字节是完整的7条指令,写入12字节指令,不会破坏后面的指令.

写入跳转指令后

[cpp] view plain copy

 

 

1. kernel32!CreateProcessInternalW:  
2. 00000000`7738e750 48b8001055fbfe070000 mov rax,offset x64dll!FakeCreateProcessInternal (000007fe`fb551000)  
3. 00000000`7738e75a ffe0            jmp     rax  
4. 00000000`7738e75c 4157            push    r15  
5. 00000000`7738e75e 4881ec400b0000  sub     rsp,0B40h  
6. 00000000`7738e765 488b0564cc0e00  mov     rax,qword ptr [kernel32!local_unwind+0x606b1 (00000000`7747b3d0)]  
7. 00000000`7738e76c 4833c4          xor     rax,rsp  
8. 00000000`7738e76f 48898424300b0000 mov     qword ptr [rsp+0B30h],rax  
9. 00000000`7738e777 4889a42438050000 mov     qword ptr [rsp+538h],rsp  

完整代码如下.

少NTDLL.h的朋友可以去搜索下载,也可以把RtlAdjustPrivilege替换成AdjustTokenPrivileges,效果样的,只是代码多几行而已.

声明:本人很菜,水平有限,汇编功底也是相当的水,如发现有误人子弟之处,敬请指正.若您有更好的方法也请多多指教.

编译成DLL后,在运行里执行rundll32.exe X64Dll.dll,Setup,DLL会自动注入到explorer.exe进程.

完全工程及编译好的文件点击打开链接

顺便说下,CreateRemoteThread在WIN7下是可以用的,问题不在CreateRemoteThread,而是在OpenProcess打开进程的权限

权限设为

[cpp] view plain copy

 

 

1. PROCESS_CREATE_THREAD|PROCESS_VM_OPERATION|PROCESS_VM_WRITE|PROCESS_VM_WRITE|PROCESS_QUERY_INFORMATION  

就可以了,WIN7( 32/64)测试都没问题

小试X64 inline HOOK,hook explorer.exe--->CreateProcessInternalW监视进程创建
