Hey Folks, today in this tutorial we are going to share with you a cloud based remote android management suite called “L3MON”. L3MON is an cloud based remote android management suite but for now we’ll configure it on localhost in our kali linux operating system. L3MON android management suite is designed in NodeJS language. If seen, it is a type of android management tool that creates a fully undetectable payload for the android operating system and has access to the entire device.

Features of L3MON

  • 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 Builde

Let’s take a look πŸ˜› !!

Install Dependencies – NodeJs

As we know that the entire project is coded in nodejs, so we have to install nodejs in our system in order to operate it. In addition, we have to install NPM package manager to publish Nodejs projects.

Install PM2

Basically pm2 allows us to handle application deployments and keep applications alive forever. So you need to install it by using the following command.

Tool Installation

Download the entire tool from github with git command, go to the directory and then its server directory and execute the “npm” command.

Opps πŸ˜› !! After executing the command you will get an error which we have highlighted which you need to execute to fix the issues.

Now start and daemonize the application by using the following command.

Make pm2 auto-boot at server restart by using the following command.

Hmm πŸ˜› !! We followed all the above instructions to check if it worked. Everything is fine, So we need to shut it down again to do some required configuration in the server.

We need to change the password to MD5 hash encryption and put it in the configuration file to secure the admin panel. You can change the password according to the command below.

Usage πŸ˜› !! echo -n “Your Password” | md5sum

Good πŸ˜› !! Now here you can keep the username and password as per your choice but only add MD5 hash value to the password.

BOOT πŸ˜› !! Everything is done and now we need to restart all the servers again.

Nice πŸ˜› !! In just one attempt we have successfully configured this tool on our localhost. Just use the following location, execute it on our browser, enter the username “admin” and password “12345″ and that’s it you will redirect to the admin panel.

APK Building

Without wasting time, just go to the APK Builder section and give the localhost IP address and enter the port according to you.

Good πŸ˜› !! It only takes 10 to 20 seconds to create android trojan. Once the payload is created, just download it and share it to the victim as per you.

FUD Payload

BOOM πŸ˜› !! It is very important whether the payload is detectable or not ? But in this case our payload is completely undetectable as you can see in the image below.

Great πŸ˜› !! Once the victim has installed it and enabled the necessary permissions then you will get full access to the android phone. As you can see in the image below, we have got more information about the victim’s phone such as his IP address, device name and more.

Once you enter the manage button, you will get all these options to manage the victim phone.

GPS Information

You can track the exact location of the victim mobile.

Contact Info

It has dumped all saved contacts on the victim mobile.

Call Logs

You can see recent and previous calls on the victim’s mobile.

SMS Manager

Through this facility you can view all the messages as well as send the message to another person through the victim mobile.

WIFI Manager

You can get the details of the previously connected wifi network.

Installed Applications

You can also monitor what kind of applications are already installed into the victim’s mobile.

File Explorer

The main feature came at the end from where you can control the entire file manager of the victim mobile.

It’s an truly Full Undetectable Payload (FUD) for Android Operating System.

  7. Hello. i am getting an error while the apk is built

    “Wrong JAVA version installed. Detected OPENJDK version “11.0.11-ea. Please use java 1.8.0

      1. # update-alternatives –config java
        There is only one alternative in link group java (providing /usr/bin/java): /usr/lib/jvm/java-11-openjdk-amd64/bin/java
        Nothing to configure.

        i am tryin to install openjdk-8, but the repo are not trying to find it

    1. execute this command.
      update-alternatives –config java

      Note : mkae sure give two hyphens before the config as it may give error if you copy and paste this command directly on the terminal.

  8. Hey dude w0rks on localserver πŸ™‚
    but can u plz say how to do it over wan plz plz ??
    plz help me in it ;(

  9. Great blog. I will not fail to follow him !
    For error: openjdk β€œ11.0.11”. Please use java 1.8.0, update-alternatives –config java don’t work.
    On repository default kali linux for exemple, java 11 is older version.
    The solution is to install SDK : https://sdkman.io/
    Installation page : https://sdkman.io/usage
    Then execute sdk install java 8.0.292-open, reboot the system after.
    Well done, it’s work ! πŸ˜‰
    Don’t forget to change your version of java if necessary.
