Phishing pages used for Malware Delivery

Fake Patanjali Yoga Gram Payment Page delivers SMS stealer malware  

Patanjali Yoga Gram is a center in India that provides holistic treatment through the integrated use of Yoga, Naturopathy, herbs, and medicinal plants.

During our routine Open-Source Intelligence (OSINT) research, Cyble Research Labs came across a Twitter post wherein researchers have mentioned a Phishing URL that is also used to deliver SMS stealer malware.

Our analysis found that the Threat Actors (TAs) have hosted phishing pages where they pretend to assist users with failed Patanjali Yoga Gram Registration or payment issues.

These TAs further exploit these pages by stealing sensitive banking information such as card details, net banking credentials, etc., and dropping an APK file capable of stealing incoming SMSs and sending them to a number provided by the TA’s server without the victim’s knowledge.

Technical Analysis

Cyble Research Labs believes that the user could have received a spam email containing the phishing URL that steals sensitive banking information and would serve to deliver the malware to unsuspecting users.

When a user first visits the URL: hxxps://srqc[.]online/, they will see a page with the Patanjali logo and a form that requests the patient’s full name, failed transaction type (i.e., ATM card, net banking), and registered mobile number. Refer to Figure 1.

While monitoring the traffic, we identified that these details were being uploaded to the server through URL: hxxps://srqc[.]online/controller/api/common/insert2.php, as shown in the below figure.

As this malicious activity is based on the Patanjali Yoga Gram payment process, in this phase, it redirects to a page where it asks users to confirm the refund mode for online money transfer. Refer to Figure 3.

In the next stage, the malware asks for banking information such as card details or net-banking credentials as per the user’s selection and uploads them to the server through URL: hxxps://srqc[.]online/controller/api/common/update.php as shown in Figures 4 & 5.

After the user has provided card details such as card number, expiry date, and CVV, the malware also requests and uploads the PIN for these cards. Refer to Figures 6 & 7.

After gaining access to these banking credentials, the malware drops an Android APK with the name “Customer_Support’ from the server URL: hxxps://srqc[.]online/Customer_Support.apk, as shown in the below figure.

The malware also requests for the OTP sent by the banks to the user’s registered mobile number or email ID and sends it to the server, as shown in Figures 9 & 10.

APK Analysis

While analyzing the dropped APK file, we observed it has a package name that contains a string related to a major international bank. This leads us to believe that the TAs could possibly also be involved in other malicious activities related to various banks.

APK Metadata Information

  • App Name:  Customer Support
  • Package Name: com.helpdev.[redacted]_support
  • SHA256 Hash: 87a9b872cd82d56f02632949a5af82f700125692f5f1561c088b5ace317b5abf

Figure 11 shows the metadata information of an application.

Manifest Description

The malware requests users for 8 different permissions, out of which it abuses 5. These dangerous permissions are listed below.

READ_SMSAccess SMSs from the victim’s device.
RECEIVE_SMSIntercept SMSs received on the victim’s device
SEND_SMSAllows an application to send SMS messages.
READ_PHONE_STATEAllows access to phone state, including the current cellular network information, the phone number and the serial number of this phone, the status of any ongoing calls, and a list of any Phone Accounts registered on the device.
READ_PHONE_NUMBERSAllows read access to the device’s phone number

As shown below, we observed a defined launcher activity in the malicious app’s manifest file, which loads the application’s first screen.

Source Code Review

During our analysis, we observed that the malware initially requests the users to allow the READ_SMS permission. After that, it hides its icon from the device’s screen.

The malware uses the code snippet shown in the below image to hide its icon from the device screen.

The malware reads the incoming SMSs and sends their content to the number provided by the TA’s server. Refer to Figure 15.

The below code snippet shows that the malware sends the incoming SMSs to the number provided by the TAs.

Patanjali Yoga Gram provides treatment for various health issues and diseases through the integrated use of Yoga, Naturopathy, herbs, and medicinal plants. It is one of the largest providers of Ayurvedic/Yogic treatment in the world. Yoga is a set of physical, mental, and spiritual practices or disciplines that originated in ancient India and aims to control and still the mind as well as improve physical fitness. It has since gained popularity across the world.

The TAs behind this particular malware perform malicious activities to steal sensitive information to exploit the patients and users of Patanjali products; in this case, the attackers are stealing banking information. There is also the ever-present threat of TAs using this sensitive data to commit financial fraud and further propagate the malware to other devices.
