L3MON is a remote Android management suite, we can use it to gain access on any android smartphone. In easy words, this is an Android RAT (Remote Administrative Tool).

In today’s detailed tutorial we learn how to install & configure L3MON on our Kali Linux system and use it.

Using L3MON we can make an Android APK payload and send it to android device and after installing it on the android device we can gain the access of Android device via L3MON’s web-based interface, we can send commands from the easy web-based interface and execute our commands on targeted devices.

L3mon has lots of beautiful features they are the following:

  • GPS Logging
  • Microphone Recording
  • View Contacts
  • SMS Logs
  • Send SMS
  • Call Logs
  • View Installed Apps
  • View Stub Permissions
  • Live Clipboard Logging
  • Live Notification Logging
  • View WiFi Networks (logs previously seen)
  • File Explorer & Downloader
  • Command Queuing
  • Built-In APK Builder

  Installing L3MON in Kali Linux

We need Java Runtime Environment 8 and nodejs installed in our machine to run L3mon.

First, we install the JRE (Java Runtime Environment) on our system by applying the following command:

sudo apt-get install openjdk-8-jre 

This command will install JRE version 8 on our system as shown in the following screenshot.

We already have installed JR

Then we need to install NodeJs on our system we apply the following commands to download nodejs in our system.

curl -sL https://deb.nodesource.com/setup_13.x | sudo bash -

Then we run the following command to install it.

sudo apt-get install -y nodejs]

Then we install pm2 process manager by using the following command:

sudo npm install pm2 -g
Now we are ready to install and configure L3MON.

We download it from it’s GitHub by using git clone command:

wget https://github.com/D3VL/L3MON/releases/download/1.1.2/L3MON-v1.1.2.zip

This command will download L3MON in our system. Now we create a new folder in our Desktop named L3MON and copy the downloaded zip file there.

Then extract it by right-clicking on the zip file and choose “extract here”.

Then we open a terminal window and navigate to L3MON in our Desktop by simply using cd command:

cd /Desktop/L3MON

Here we install all the dependencies by using the following command:

npm install
It will install the dependencies now as we can see the following screenshot:

Let start the server by using the following command:

pm2 start index.js

Now we can see our server in our browser http://localhost:22533 there will be a login page as the following screenshot:

We create a login for our server here. But we can’t log in because we did not create a password to log in. To create a password we stop our service by using the following command:

pm2 stop index.js

Now we need to edit maindb.json file using our favourite text editor mousepad.

mousepad maindb.json

Here we edit the username if we want it. But in the password field, we need to give our password’s md5 hash. Means if we fill here the password as plain text, will not work. We just need to put the password’s md5 hash.

How to create a md5 hash of a password? Suppose our password is qwerty (This is for an example we shouldn’t choose easy passwords for security reasons). To convert it on md5 we need to use the following command in another terminal window.

echo -n "qwerty" | md5sum | cut -d" " -f 1

Here we got the MD5 hash of our password as we can see in the following screenshot.

Then we fill our username and password in maindb.json file then save and close this file.

Now we again start the server by using the following command :

pm2 start index.js

Then again open our localhost in browser with 22533 port.

As we set our username kali and password qwerty we fill it and click on login.

We are successfully logged in.

Now we are in control. We need to open the APK builder tab.

Here we put our IP address (local or public) and leave the port as default and click on build.

Note: If we want to control android device on our local network (same WiFi) then we can use our local IP and to connect devices through the internet we need to put our Public IP (Static IP is preferred for a long time use).

After clicking on the build you may get an error like this.

We solved this error by configuring JAVA in another terminal by running following command:

update-alternatives --config java

Then we type 2 and enter.
Then we restart our running L3MON server by using the following command:

pm2 restart all

Bingo, the error goes now the build is ready to download.

Now we can download the L3MON.apk in our system, and send it to our targeted device anyway and make a successful installation.

After successful installation, it on the targeted device and the phone user tries to open this L3MON will asks all the permission of devices and automatically hide from the app drawer.

After this, we got a connection with the device. We can check it on our Devices tab.

Now we can control this phone from the manage button. Here in the following screenshot, we are in the file manager of the phone. Now we can spy on this phone.

We are in the file manager of the victim device

Our downloaded data and recorded audio clips will be saved under assets/webpublic/client_downloads/ directory.

Our discussed method is for the local network. To connect a device from the internet we prefer to have a static IP address and forward our default port 22533 in our router settings or we can change the default port by changing these lines (inside includes/const.js).

Using this method we can control phones connected in our same network. We also can control devices through internet by using ngrok services. Configuring L3MON on VPS will make it portable and useful.
