Let’s dig deeper by decompiling the app using dex2jar&JD-GUI. So, we need to do further analysis to confirm if the app has any malicious behavior. If you are done with exploring the file opened with vim editor, press ctrl+c and then enter :q! to get out of it. INTERNET is the only permission that is required by this app, but that doesn’t confirm that it is malicious as most of the apps these days require internet permission for most of their functionality. Even this app is not asking for any dangerous permissions. Looking at the above content, there isn’t anything suspicious. Let’s view the contents of it using the following command and see if anything is interesting. Run the following command from analysis folder to navigate to the newly created bake_the_cake folder.Īnd then, run ls command to list the files and folders inside the current folder.Īs you can see in the above figure, this listing has got AndroidManifest.xml file in it. Navigate to the folder and list the files and folders inside it as shown in the figure below.

The above command would create a new folder with the apk file’s name. Java -jar apktool_2.1.1.jar d bake_the_cake.apk Now, run the following command to disassemble the apk file and it should work fine. Now, let’s get the latest version of apktool. You can run the above command from anywhere in the terminal. Remove “1.apk” file under “/home/infosec/apktool/framework/” folder using the following command: Let’s use apktool and get it using the command shown below.īut, before we do this, we should make sure that we are using the latest version of apktool and delete 1.apk from apktool’s framework directory as the existing apktool that comes with Santoku is outdated and it might not be able to disassemble our target apk file. We can get the AndroidManifest.xml file using multiple ways. Let’s begin with analyzing the AndroidManifest.XML file.

Static Analysis involves decompiling the application and looking at the source code and analyze it to understand what the malware is doing.

Once it is started, you should see an emulator as shown below.Ĭongratulations! You have created your emulator for analyzing the Android malware sample. You should see the following confirmation dialogue.Ĭlick “Launch” and it starts the emulator showing the following progress bar.īe patient and wait for a while as the emulator may take a longer time to launch when you do it for the first time. Once if you are done with the steps shown, you should see an additional Virtual Device as shown below.Ĭhoose the newly created emulator and click “Start” button to start the emulator. Finally, we have provided 100 MB for the SD Card.Ĭross check everything and click “OK” to complete the setup. Then, we chose to have “Android 4.4.2-API Level 19” as our target. Now, let’s choose the appropriate options as shown below.Īs you can see in the above figure, we have named our emulator “analysis_device.” Then, we chose a device with “3.2-inch HVGA” to have an emulator with the smaller size. Now, let’s create a new emulator with the specifications of our choice.Ĭlick “Create” and you should see the following window. This will open up “Android Virtual Device(AVD) Manager” window as shown below.Īs you can see in the above figure, we already have one emulator configured. Once if everything is set, click “Tools” in the menu bar at the top of the window and then click “Manage AVDs” as shown below. If you notice the above figure, we have already installed “Android 4.4.2 ARM EABI v7a System Image.”

Depending on the requirement, we should download Android images to create an appropriate emulator. The above step will open up the following window.īy default, Santoku consists of images of only a few Android versions. Navigate to “Santoku->Development Tools” and Click “Android SDK Manager”.
We will begin this exercise by creating an emulator, which is required in a later section. Steps to set up an Android Virtual Device: Tools: AVD Manager, ADB, Wireshark, dex2jar, apktoolįiles used in this lab: bake_the_cake.apk, apktool, tcpdump, List of VMs used: This lab exercise makes use of Santoku Linux VM.
