Introduction:

Cybercriminals can hack your phone using or exploiting some public charging stations such as at airports, Malls, hotel rooms, etc. When you plug in your phone or laptop devices into a power charger using USB, you may be plugging into a hacker. Juice jacking poses a security threat at public charging stations at airports, shopping malls and other public places that provide free charging stations for mobile, tablet, and laptop devices. 

Cybercriminals can either hack into the public charging spot or download malware or viruses through the USB port into your system. When you plug your phone, laptop, tablet or other such devices for charging at public charging stations, it can download malware to your phone and other such devices, and then hackers can access your personal information or passwords, It is really a problem since hackers can even get access to your bank account for unauthorised transactions by accessing your passwords and personal information. 

Hence it is important to think twice before using public charging spots, as it might lead to serious consequences such as malware, data leak and hacking. Hacking can gain unauthorised access to your personal information by installing malware in your device and they might monitor your device by installing monitor software or spyware to your device. This scam is referred to as juice jacking. 

FBI issued an advisory  warning about using public charging stations:

The Federal Bureau of Investigation (FBI), In May 2023, advised users to avoid using free charging stations in airports, hotels, or shopping centres. The warning comes as threat actors have figured out ways to inject malware into devices attached to publicly installed USB ports.

Updated Security measures:

We all must have seen public charging points such as airports, shopping malls, metro, and other public places that provide charging stations for mobile devices. But it can be a threat to your stored data on your device. During the charging process, your data can be transferred which can ultimately lead to a data breach. Hence utmost care should be taken to protect your information and data. iPhones and other devices have security measures in place, When you plug your phone into a charging power source, a pop-up appears to ask permission to allow or disallow the transfer of Data. There is also a default setting in the phones where data transfer is disabled. In the latest models, when you plug your device into a new port or a computer, a pop-up appears asking whether the device is trusted or not. 

Two major risks involved in the threat of Juice jacking: 

1. Malware installation: – Malware apps can be used by bad actors to clone your phone data to their device, Your personal data is transferred leading to a data breach. Some types of malware include Trojans, adware, spyware, crypto-miners, etc. Once this malware is injected into your device, It is easy for cybercriminals to extort a ransom to restore the information they have unauthorized access to.
2. Data Theft: It is important to give emphasis to the question of whether your data is protected at public charging stations? When we use a USB cable and connect to a public charging station port, cyber-criminals by injecting malware into the charging port system, can inject the malware into your device or your data can be transferred to the bad actors. USB cords can be exploited by cybercriminals to commit malicious activities.

‍

Best practices: 

• Avoid using public charging stations: Using public charging stations is not safe. It is very possible for a cybercriminal to load malware into a charging station with a USB cord. Hence It is advisable not to use public charging spots, try to make sure you charge your phone, and laptop devices in your car, at home or office so it will help you to avoid public charging stations.
• Alternative method of charging: You can carry a power bank along with you to avoid the use of public charging stations.
• Lock your phone: Lock your phone once connected to the charging port. Locking your device once connected to the charging station will prevent it from being able to sync or transfer data.
• Software update: It is important to enable and use your device’s software security measures. Mobile devices have certain technical protections against such vulnerabilities and security threats. 
• Review Settings: Disable your device’s option to automatically transfer data when a charging cable is connected. This is the default on iOS devices. Android users should disable this option in the Settings app. If your device displays a prompt asking you to “trust this computer,” it means you are connected to another device, not simply a power outlet. Deny the permission, as trusting the computer will enable data transfers to and from your device.  So when you plug your device into a USB port and a prompt appears asking permission to "share data" or “trust this computer” or “charge only,” always select “charge only.”

Conclusion:

Cybercriminals or bad actors exploit public charging stations. There have been incidents where malware was planted in the system by the use of a USB cord, During the charging process, the USB cord opens a path into your device that a cybercriminal can exploit, which means the devices can exchange data. That's called juice jacking. Hence avoid using public charging stations, our safety is in our hands and it is significantly important to give priority to best practices and stay protected in the evolving digital landscape.

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.
