Freeway for Network Pentesting

Read the article about Freeway, now on Medium

Note

User will not be prompted to accept EULA anymore!
Therefore, by downloading the software, user automatically agrees to follow every guideline specified in EULA section below.

1. Overview

Freeway is a Python scapy-based tool for WiFi penetration that aim to help ethical hackers and pentesters develop their skills and knowledge in auditing and securing home or enterprise networks.

2. Features

• IEEE 802.11 Packet Monitoring
• Deauthentication Attack
• Beacon Flood
• Packet Fuzzer
• Network Audit
• Channel Hopper
• Evil Twin
• Packet Crafter

_{Description of the features can be found in Section 6}

3. Preparation

It is necessary to have:

• A network adapter supporting monitor mode and frame injection.
• An operating system running a Linux distribution.
• Python 3+ installed.

_{Optionally, install Scapy and Rich packages for Python if not installing via pip (see Section 4)}

4. Setup

Option A: Install via PyPi (RECOMMENDED)

  $ sudo pip install 3way

Option B: Install or run manually

First, clone the repository:

git clone https://github.com/FLOCK4H/Freeway

Navigate to the cloned repository:

cd Freeway

Option 1: Install dependencies, folders, and Freeway. (RECOMMENDED)

_{This will allow to launch the tool from anywhere}

sudo pip install .

Option 2: Run without installation using Python.

_{Must be called from the /Freeway directory}

sudo pip install scapy rich
sudo python Freeway

5. Usage

This tool comes with its own command line interface (CLI) and can be run without specifying any additional arguments.

Click to expand the CLI usage

sudo Freeway

Follow the prompt to select the network adapter (see Section 3):

[!TIP} These screenshots show Freeway in its very first iteration, these do not reflect how software looks now, and are to change in the future.

Select the feature and parameter(s):

And with the additional arguments, to skip the CLI partially or completely.

Click to expand the arguments usage

sudo Freeway -i wlan2 -a monitor -p 1,2,a

_{'-p' is not required with '-a', e.g., this will prompt for parameters to specify in the CLI:}

sudo Freeway -i wlan2 -a deauth

All arguments, actions, and parameters:

  Arguments:
  -h, --help     Show the help message. 

  -i, --inf      Specify the WLAN interface (e.g., wlan0, wlan1). 

  -a, --action   Action number or alias (e.g., 1 or monitor). 

  -p, --params   Parameter identifiers (e.g., 1,2,a or 3rtv, depends on action). 

Actions:
1 or monitor,
2 or deauth,
3 or beacon_spam,
4 or fuzzer,
5 or audit,
6 or hopper,
7 or eviltwin
8 or packet_crafter
Parameters must be provided in the same format as in the CLI, specific for every action.
To list all parameters for a given action, just provide -a argument without -p.

6. Details

• Packet Monitor - Sniffs the WiFi packets in the air, analyze them and return the result onto the python's curses display. Catches SSIDs, MACs, Clients, Uptime, Channel, Signal (dBm), Encryption and resolves manufacturer. Catches PMKIDs in hashcat crackable format, and 4-way Handshakes, as well as other EAPOL packets. Logs the captured session to the /caps folder or every captured packet if Save output was selected.
• Deauthentication Attack (Deauthing) - Disconnects a device from the network by sending a packet containing AP¹ address, device address (or broadcast for Mass Deauthing) and the deauthentication frame with a reason of kicking the client(s). In case where a device address is a broadcast address, the AP will in most cases disconnect all clients at once. Freeway creates separate thread for every AP or client found in order to make deauthing maximally efficient.
• Beacon Flood Attack - Floods the nearby WiFi scanners with fake or malformed APs. It can cause the devices looking for WiFi to behave abnormally (e.g. crash, freeze, drain the battery or run slower) and disrupt the nearby network traffic. User is able to specify his own ssid list, use the default one and generate correct (but random) or malformed beacon packets.
• Packet Fuzzer - Fuzzing is a technique of network vulnerability assesment by sending a wide array of malformed or semi-random data to network interfaces and observing the responses. Freeway covers: Replay captured packets (RX&TX²), Spam CTS/RTS or Probe requests and Flood an AP with Authentication or Association Frames. Devices that will capture fuzzed packets will behave differently depending on vulnerability level of receiver (!USE WITH CAUTION!).
• Network Audit - Gathers all possible information about specific network and returns them onto the curses view. Tracks all clients signal and last activity, as well as resolve the manufacturer.
• Channel Hopper - Changes the current channel of the network adapter. Helpful in making specific attacks more successful.
• Evil Twin - Hosts a legitimate Access Point with Captive Portal, this 'legitimate' AP asks user for login/ bank credentials, or to download malware. First, there's a normal AP created, most times with an ESSID and MAC of existing network. Then, we host our captive portal (e.g., login website), so a normal web server, that reroutes users to our index.html trying to associate with the network we spoof.
• Packet Crafter - Allows to construct proper .11 frames, modify them with custom values, and send in the air using multiple interfaces on a custom number of threads. Useful for quick packet delivery, educational activities, or threaded/ multi-node penetration. All encapsulated in a user-friendly interface with prompt-after-prompt typing.

Known Issues

1. Android filters out fake beacon frames (works for Android 5, doesn't on Android 11+, versions below Android 11 and above Android 5 were not tested.)
2. EvilTwin needs a second adapter connected to the internet (not really an issue), to be able to reroute traffic
3. The very first run of the EvilTwin may not succeed if dnsmasq wasn't ever ran on the machine, run EvilTwin twice, or install and run dnsmasq before.
