Android Malware Mimics MYT Müzik App to Target Turkish Users
GodFather is a notorious Android banking trojan known for targeting banking users, mostly in European countries. Cyble Research & Intelligence Labs (CRIL) blogged about this GodFather android malware in March 2022 and explained how it targeted android banking users worldwide. Recently, CRIL identified several GodFather Android samples masquerading as MYT application. This application has the name MYT Müzik which is written in the Turkish language. Thus, we suspect this application targets Android users in Turkey.
The GodFather samples analyzed are encrypted using custom encryption techniques to evade detection by the anti-virus products. Upon installing this application on our testing device, we observed that it uses an icon and name similar to a legitimate application named MYT Music which is hosted on the Google Play Store with more than 10 million downloads. The image below shows the malicious application’s icon and name on the Android device’s screen.

The GodFather Android malware, after successful installation on the victim’s device, steals sensitive data such as SMSs, basic device details, including installed apps data, and the device’s phone number. Apart from these, it can also control the device screen using VNC, forwarding incoming calls of the victim’s device and injecting banking URLs.

Figure 2 shows the metadata information of an application.

Manifest Description
The malware requests 23 different permissions from the user, out of which it abuses at least 6. These dangerous permissions are listed below:
Permissions | Description |
READ_CONTACTS | Access phone contacts |
READ_PHONE_STATE | Allows access to phone state, including the current cellular network information, the phone number and the serial number of the phone, the status of any ongoing calls, and a list of any Phone Accounts registered on the device. |
CALL_PHONE | Allows an application to initiate a phone call without going through the Dialer user interface for the user to confirm the call. |
WRITE_EXTERNAL_STORAGE | Allows the app to write or delete files in the device’s external storage |
DISABLE_KEYGUARD | Allows the app to disable the keylock and any associated password security |
BIND_ACCESSIBILITY_SERVICE | Used for Accessibility Service |
Source Code Review
The malicious application uses the code below to hide/unhide its icon from the device screen.

The below image shows the code snippet used by the malware for collecting Victim’s device details, such as device model info, installed apps list, etc., and uploading them to the TAs’ server.

The malware can do money transfers by making USSD (Unstructured Supplementary Service Data) calls without using the dialer user interface, as shown in the figure below.

The malware creates an overlay window in the OnAccessibilityEvent method and injects HTML phishing pages when it receives sunset_cmd from the TAs C&Cserver, as shown in the below image.

Upon receiving the command from the C&C server, the malware forwards Victim’s incoming calls to a number provided by the TAs’.

The image shown below contains the code through which the malware can steal application key logs.

The malware uses the below-shown code to view/control the victim device’s screen using a VNC viewer.

The malicious application gets the C&C server URL from a telegram channel: hxxps://t[.]me/varezotukomirza, through which it communicates with the TAs to get the commands and sends the stolen data from the device.

The malware terminates itself after receiving a “killbot” command from TAs C&C server. The below-shown code snippet depicts the same.

The malware uses the below commands to extract sensitive information from the user’s device.
Command-List |
startUSSD |
sentSMS |
startApp |
startforward |
killbot |
send_all_permission |
vnc_open |
keylog_active |

Conclusion
GodFather Android Banking trojan was seen targeting European users at the beginning of the year 2022. Now, it comes back with advanced encryption techniques used to obfuscate its code. This shows the TA’s ability to continuously enhance their techniques to target people with avoiding detections from Anti-virus programs.
As per the research, such malware is distributed via sources other than Google Play Store. As a result, practicing basic cyber hygiene across mobile devices and online banking applications effectively prevents such malware from compromising your devices.
Our Recommendations
We have listed some essential cybersecurity best practices that create the first line of control against attackers. We recommend that our readers follow the best practices given below:
How to prevent malware infection?
- Download and install software only from official app stores like Google Play Store or the iOS App Store.
- Use a reputed anti-virus and internet security software package on your connected devices, such as PCs, laptops, and mobile devices.
- Use strong passwords and enforce multi-factor authentication wherever possible.
- Enable biometric security features such as fingerprint or facial recognition for unlocking the mobile device where possible.
- Be wary of opening any links received via SMS or emails delivered to your phone.
- Ensure that Google Play Protect is enabled on Android devices.
- Be careful while enabling any permissions.
- Keep your devices, operating systems, and applications updated.
How to identify whether you are infected?
- Regularly check the Mobile/Wi-Fi data usage of applications installed on mobile devices.
- Keep an eye on anti-viruses and Android OS alerts and take necessary actions accordingly.
What to do when you are infected?t
- Disable Wi-Fi/Mobile data and remove SIM cards – as in some cases, the malware can re-enable the Mobile Data.
- Perform a factory reset.
- Remove the application in case a factory reset is not possible.
- Take a backup of personal media Files (excluding mobile applications) and perform a device reset.
What to do in case of any fraudulent transaction?
- In case of a fraudulent transaction, immediately report it to the concerned bank.
What should banks do to protect their customers?
- Banks and other financial entities should educate customers on safeguarding themselves from malware attacks via telephone, SMS, or emails.
