I Think, That’s App has Something Wrong!

Hello Cyberman!

How are you? I hope, you are nice. This article subject Android APK and its evil event.
I’m have a friend and did help for him. He did want me android app change logo and name.
I did question “Why it?” He said me “want has a friend phone call listen.” I said okay! And I did it.

Firstly What Is The APK?

I think anyone reading this blog knows what an APK is. Still, it’s worth giving an explanation. APK, short for APK Android Package Kit, is the package file format used by the Android operating system for the distribution and installation of mobile applications.

Well, I thought I need an apk for call listening. And then my friend gave name a apk. It is name “Cube ACR” Then I did research for Cube ACR. And saw it is APK nice.

Requirement list

Here is the list of what is required for this operation:
– APK File (You can find it from this link.)
BlueStack or another android emulator (For testing.)
Dex2Jar  and APKTool (For Android APK decompression and recompile.)
Java must be installed on your system. (For Dej2Jar and APKTool.)

Let’s extract APKTool and Dex2Jar files to the same folder.
And let’s create a “.bat” file in the relevant directory. Let’s copy and paste the source code of the created file as well as this GitHub link.

And finally, let’s save the folder we created in the environment variables. (You can find lots of videos on how to do it online.)

 It should look like the picture above. And navigate to the corresponding directory path in the CMD or PowerShell screen.

(For Windows users.) As seen in the picture above. And then enter in command “apktool.bat d cube.apk” Then push “enter”.

 As seen above picture, now apk codes out in directory. Now it is necessary to open the codes as a project with any IDE (Intellij IDEA, JD-GUID, NetBeans, Eclipse, Android Studio It doesn’t matter.) and change the source codes. 

The Android Manifest.xml file contains the information of the application name and images. We just changed those parts. And we showed it like “Samsung Health” app available on Samsung devices.

Then, what needs to be done to recompile the codes is to enter “apktool.bat b cube” on the CMD or PowerShell screen.

You have a new app called “Samsung Health” that listens to phone calls. It will be enough to install it on the victim’s device.

I deliberately did not write this article in detail. Because the codes etc. It would not be very accurate to show. Have a nice day with lots of informatics 🙂
