#FactCheck - Viral Post of Gautam Adani’s Public Arrest Found to Be AI-Generated

Executive Summary:

Recently, CyberPeace faced a case involving a fraudulent Android application imitating the Punjab National Bank (PNB). The victim was tricked into downloading an APK file named "PNB.apk" via WhatsApp. After the victim installed the apk file, it resulted in unauthorized multiple transactions on multiple credit cards.

Case Study: The Attack: Social Engineering Meets Malware

The incident started when the victim clicked on a Facebook ad for a PNB credit card. After submitting basic personal information, the victim receives a WhatsApp call from a profile displaying the PNB logo. The attacker, posing as a bank representative, fakes the benefits and features of the Credit Card and convinces the victim to install an application named PNB.apk.  The so called bank representative sent the app through WhatsApp, claiming it would expedite the credit card application. The application was installed in the mobile device as a customer care application. It asks for permissions such as  to send or view SMS messages. The application opens only if the user provides this permission. 

‍

It extracts the credit card details from the user such as Full Name, Mobile Number, complain, on further pages irrespective of  Refund, Pay or Other. On further processing, it asks for other information such as credit card number, expiry date and cvv number. 

‍

Now the scammer has access to all the details of the credit card information, access to read or view the sms to intercept OTPs. 

The victim, thinking they were securely navigating the official PNB website, was unaware that the malware was granting the hacker remote access to their phone. This led to ₹4 lakhs worth of 11 unauthorized transactions across three credit cards.

The Investigation & Analysis:

Upon receiving the case through CyberPeace helpline, the CyberPeace Research Team acted swiftly to neutralize the threat and secure the victim’s device. Using a secure remote access tool, we gained control of the phone with the victim’s consent. Our first step was identifying and removing the malicious "PNB.apk" file, ensuring no residual malware was left behind. 

Next, we implemented crucial cyber hygiene practices:

1. Revoking unnecessary permissions – to prevent further unauthorized access.
2. Running antivirus scans – to detect any remaining threats.
3. Clearing sensitive data caches – to remove stored credentials and tokens.

The CyberPeace Helpline team assisted the victim to report the fraud to the National Cybercrime Portal and helpline (1930) and promptly blocked the compromised credit cards.

The technical analysis for the app was taken ahead and by using the md5 hash file id. This app was marked as malware in virustotal and it has all the permissions such as Send/Receive/Read SMS, System Alert Window.  

‍

In the similar way, we have found another application in the name of “Axis Bank” which is circulated through whatsapp which is having similar permission access and the details found in virus total are as follows:

Recommendations:

This case study implies the increasingly sophisticated methods used by cybercriminals, blending social engineering with advanced malware. Key lessons include:

• Be vigilant when downloading the applications, even if they appear to be from legitimate sources. It is advised to install any application after checking through an application store and not through any social media. 
• Always review app permissions before granting access.
• Verify the identity of anyone claiming to represent financial institutions.
• Use remote access tools responsibly for effective intervention during a cyber incident.

By acting quickly and following the proper protocols, we successfully secured the victim’s device and prevented further financial loss.

Introduction:

A new Android malware called NGate is capable of stealing money from payment cards through relaying the data read by the Near Field Communication (“NFС”) chip to the attacker’s device. NFC  is a device which allows  devices such as smartphones to communicate over a short distance wirelessly.  In particular, NGate allows forging the victims’ cards and, therefore, performing fraudulent purchases or withdrawing money from ATMs. . 

 About NGate Malware: 

The whole purpose of NGate malware is to target victims’ payment cards by relaying the NFC data to the attacker’s device. The malware is designed to take advantage of phishing tactics and functionality of the NFC on android based devices. 

Modus Operandi: 

• Phishing Campaigns: The first step is spoofed emails or SMS used to lure the users into installing the  Progressive Web Apps (“PWAs”) or the WebAPKs presented as genuine banking applications. These apps usually have a layout and logo that makes them look like an authentic app of a Targeted Bank which makes them believable. 

• Installation of NGate: When the victim downloads the specific app, he or she is required to input personal details including account numbers and PIN numbers. Users are also advised to turn on or install  NFC on their gadgets and place the payment cards to the back part of the phone to scan the cards. 

• NFCGate Component: One of the main working features of the NGate is the NFCGate, an application created and designed by some students of Technical University of Darmstadt. This tool allows the malware to:
  • • Collect NFC traffic from payment cards in the vicinity. 
    • Transmit, or relay this data to the attacker’s device through a server. 
    • Repeat data that has been previously intercepted or otherwise copied.

It is important to note that some aspects of NFCGate mandate a rooted device; however, forwarding NFC traffic can occur with devices that are not rooted, and therefore can potentially ensnare more victims. ‍

Technical Mechanism of Data Theft:

• Data Capture: The malware exploits the NFC communication feature on android devices and reads the information from the payment card, if the card is near the infected device. It is able to intercept and capture the sensive card details.  

• Data Relay: The stolen information  is transmitted through a server to the attacker’s device so that he/she is in a position to mimic the victim’s card. 

• Unauthorized Transactions: Attackers get access to spend money on the merchants or withdraw money from the ATM that has NFC enabled. This capability marks a new level of Android malware in that the hackers are able to directly steal money without having to get hold of the card. 

Social Engineering Tactics: 

In most cases, attackers use social engineering techniques to obtain more information from the target before implementing the attack. In the second phase, attackers may pretend to be representatives of a bank that there is a problem with the account and offer to download a program called NGate, which in fact is a Trojan under the guise of an application for confirming the security of the account. This method makes it possible for the attackers to get ITPIN code from the sides of the victim, which enables them to withdraw money from the targeted person’s account without authorization.

Broader Implications of NGate: 

The ultramodern features of NGate mean that its manifestation is not limited to financial swindling. An attacker can also generate a copy of NFC access cards and get  full access when hacking into restricted areas, for example, the corporate offices or restricted facility. Moreover, it is also safe to use the capacity to capture and analyze NFC traffic as threats to identity theft and other forms of cyber-criminality. 

Precautionary measures to be taken:

To protect against NGate and similar threats, users should consider the following strategies:

• Disable NFC: As mentioned above, NFC should be not often used, it is safe to turn NFC on Android devices off. This perhaps can be done from the general control of the device in which the bursting modes are being set. 

• Scrutinize App Permissions: Be careful concerning the permission that applies to the apps that are installed particularly the ones allowed to access the device. Hence, it is very important that applications should be downloaded only from genuine stores like Google Play Store only. 

• Use Security Software: The malware threat can be prevented by installing relevant security applications that are available in the market. 

• Stay Informed: As it has been highlighted, it is crucial for a person to know risks that are associated with the use of NFC while attempting to safeguard an individual’s identity. 

Conclusion: 

The presence of malware such as NGate is proof of the dynamism of threats in the context of mobile payments. Through the utilization of NFC function, NGate is a marked step up of Android malware implying that the attackers can directly manipulate the cash related data of the victims regardless of the physical aspect of the payment card. This underscores the need to be careful when downloading applications and to be keen on the permission one grants on the application. Turn NFC when not in use, use good security software and be aware of  the latest scams are some of the measures that help to fight this high level of financial fraud. The  attackers are now improving their methods. It is only right for the people and companies to take the right steps in avoiding the breach of privacy and identity theft.
