#FactCheck - Debunked: AI-Generated Image Circulating as April Solar Eclipse Snapshot

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.

What Is a VPN and its Significance 

A Virtual Private Network (VPN) creates a secure and reliable network connection between a device and the internet. It hides your IP address by rerouting it through the VPN’s host servers. For example, if you connect to a US server, you appear to be browsing from the US, even if you’re in India. It also encrypts the data being transferred in real-time so that it is not decipherable by third parties such as ad companies, the government, cyber criminals, or others.

All online activity leaves a digital footprint that is tracked for data collection, and surveillance, increasingly jeopardizing user privacy. VPNs are thus a powerful tool for enhancing the privacy and security of users, businesses, governments and critical sectors. They also help protect users on public Wi-Fi networks ( for example, at airports and hotels), journalists, activists and whistleblowers, remote workers and businesses, citizens in high-surveillance states, and researchers by affording them a degree of anonymity. 

What VPNs Do and Don’t 

‍

•  What VPNs Can Do:
  
  • Mask your IP address to enhance privacy.
  • Encrypt data to protect against hackers, especially on public Wi-Fi.
  • Bypass geo-restrictions (e.g., access streaming content blocked in India).
•  What VPNs Cannot Do:
  
  • Make you completely anonymous and protect your identity (websites can still track you via cookies, browser fingerprinting, etc.).
  • Protect against malware or phishing.
  • Prevent law enforcement from tracing you if they have access to VPN logs.
  • Free VPNs usually even share logs with third parties. 

VPNs in the Context of India’s Privacy Policy Landscape 

In April 2022, CERT-In (Computer Emergency Response Team- India) released Directions under Section 70B (6) of the Information Technology (“IT”) Act, 2000, mandating VPN service providers to store customer data such as “validated names of subscribers/customers hiring the services, period of hire including dates, IPs allotted to / being used by the members, email address and IP address and time stamp used at the time of registration/onboarding, the purpose for hiring services, validated address and contact numbers, and the ownership pattern of the subscribers/customers hiring services” collected as part of their KYC (Know Your Customer) requirements, for a period of five years, even after the subscription has been cancelled. While this directive was issued to aid with cybersecurity investigations, it undermines the core purpose of VPNs- anonymity and privacy. It also gave operators very little time to carry out compliance measures. 

Following this, operators such as NordVPN, ExpressVPN, ProtonVPN, and others pulled their physical servers out of India, and now use virtual servers hosted abroad (e.g., Singapore) with Indian IP addresses. While the CERT-In Directions have extra-territorial applicability, virtual servers are able to bypass them since they physically operate from a foreign jurisdiction. This means that they are effectively not liable to provide user information to Indian investigative agencies, beating the whole purpose of the directive. To counter this, the Indian government could potentially block non-compliant VPN services in the future. Further, there are concerns about overreach since the Directions are unclear about how long CERT-In can retain the data it acquires from VPN operators, how it will be used and safeguarded, and the procedure of holding VPN operators responsible for compliance. 

Conclusion: The Need for a Privacy-Conscious Framework

The CERT-In Directions reflect a governance model which, by prioritizing security over privacy, compromises on safeguards like independent oversight or judicial review to balance the two. The policy design renders a lose-lose situation because virtual VPN services are still available, while the government loses oversight. If anything, this can make it harder for the government to track suspicious activity.  It also violates the principle of proportionality established in the landmark privacy judgment, Puttaswamy v. Union of India (II) by giving government agencies the power to collect excessive VPN data on any user. These issues underscore the need for a national-level, privacy-conscious cybersecurity framework that informs other policies on data protection and cybercrime investigations. In the meantime, users who use VPNs are advised to choose reputable providers, ensure strong encryption, and follow best practices to maintain online privacy and security.

Over The Top (OTT)

OTT messaging platforms have taken the world by storm; everyone across the globe is working on OTT platforms, and they have changed the dynamics of accessibility and information speed forever. Whatsapp is one of the leading OTT messaging platforms under the tech giant Meta as of 2013. All tasks, whether personal or professional, can be performed over Whatsapp, and as of today, Whatsapp has 2.44 billion users worldwide, with 487.5 Million users in India alone^[1]. With such a vast user base, it is pertinent to have proper safety and security measures and mechanisms on these platforms and active reporting options for the users. The growth of OTT platforms has been exponential in the previous decade. As internet penetration increased during the Covid-19 pandemic, the following factors contributed towards the growth of OTT platforms –

• Urbanisation and Westernisation
• Access to Digital Services
• Media Democratization
• Convenience
• Increased Internet Penetration

These factors have been influential in providing exceptional content and services to the  consumers, and extensive internet connectivity has allowed people from the remotest part of the country to use OTT messaging platforms. But it is pertinent to maintain user safety and security by the platforms and abide by the policies and regulations to maintain accountability and transparency.

New Safety Features

Keeping in mind the safety requirements and threats coming with emerging technologies, Whatsapp has been crucial in taking out new technology and policy-based security measures. A number of new security features have been added to WhatsApp to make it more difficult to take control of other people’s accounts. The app’s privacy and security-focused features go beyond its assertion that online chats and discussions should be as private and secure as in-person interactions. Numerous technological advancements pertaining to that goal have focussed on message security, such as adding end-to-end encryption to conversations. The new features allegedly increase user security on the app.

WhatsApp announced that three new security features are now available to all users on Android and iOS devices. The new security features are called Account Protect, Device Verification, and Automatic Security Codes

• For instance, a new programme named “Account Protect” will start when users migrate an account from an old device to a new one. If users receive an unexpected alert, it may be a sign that someone is trying to access their account without their knowledge. Users may see an alert on their previous handset asking them to confirm that they are truly transitioning away from it.
• To make sure that users cannot install malware to access other people’s messages, another function called “Device Verification” operates in the background. Without the user’s knowledge, this feature authenticates devices in the background. In particular, WhatsApp claims it is concerned about unlicensed WhatsApp applications that contain spyware made explicitly for this use. Users do not need to take any action due to the company’s new checks that help authenticate user accounts to prevent this.
• The final feature is dubbed “automatic security codes,” It builds on an already-existing service that lets users verify that they are speaking with the person they believe they are. This is still done manually, but by default, an automated version will be carried out with the addition of a tool to determine whether the connection is secure.

While users can now view the code by visiting a user’s profile, the social media platform will start to develop a concept called “Key Transparency” to make it easier for its users to verify the validity of the code. Update to the most recent build if you use WhatsApp on Android because these features have already been released. If you use iOS, the security features have not yet been released, although an update is anticipated soon.

Conclusion

Digital safety is a crucial matter for netizens across the world; platforms like Whatsapp, which enjoy a massive user base, should lead the way in terms of OTT platforms’ cyber security by inculcating the use of emerging technologies, user reporting, and transparency in the principles and also encourage other platforms to replicate their security mechanisms to keep bad actors at bay. Account Protect, Device Verification, and Automatic Security Codes will go a long way in protecting the user’s interests while simultaneously maintaining convenience, thus showing us that the future with such platforms is bright and secure.
