Charging your phone at the airport can be risky. The FBI has warned the public about the dangers of using free charging stations at airports, hotels, and shopping centers. These USB charging stations can be modified by hackers to install malware and monitoring software on your device, allowing them to access your personal data, financial information, and even control your phone remotely. This practice, known as juice jacking, can have serious consequences for victims. However, there are ways to keep your data secure while charging your phone in public. Using your own charger and plugging it into an electrical outlet is recommended by the FBI as a safer alternative. Additionally, carrying a portable power bank and utilizing wireless charging options can help you avoid the risks associated with USB charging stations.

The FBI warns against using airport charging stations
The FBI has issued a warning to the public against using public charging stations, especially those found in airports, malls, and hotels. The advisory, which was released by the FBI's Denver field office, highlights the risk of malware and monitoring software being installed on devices via USB charging ports.
According to the FBI, "bad actors" have devised methods to exploit public USB ports to inject malware and monitoring software into devices. This practice, known as "juice jacking," allows hackers to access sensitive data such as usernames and passwords, compromising digital privacy and leading to potential identity theft or financial loss. The FBI recommends carrying your own charger and USB cable and using a power outlet instead of public charging stations.
While the FBI's warning is a precautionary measure and there have been no specific incidents reported, it underscores the growing concern over cybersecurity threats in public spaces. The Federal Communications Commission (FCC) has previously issued similar warnings about juice jacking, urging travelers to avoid public USB charging stations and opt for power outlets or portable chargers instead.
To protect yourself from potential malware injection when using public charging stations, it is advisable to follow the FBI's recommendations. Carry your own charger and USB cable, and if possible, use wireless charging or a portable power bank to minimize direct connections to public USB ports. Additionally, if you must use a public USB charging station, select the "charge only" option if available, to prevent data transfer and reduce the risk of malware installation.
It is important to stay vigilant and take proactive steps to safeguard your personal information and digital privacy, especially when utilizing public amenities like airport charging stations. By following the FBI's guidance and staying informed about cybersecurity risks, you can reduce your exposure to potential threats and protect your data.

How to avoid data theft at the airport
Public phone charging stations, including those at airports, can be risky. According to the FBI, no public phone charging stations are safe from hackers. Attackers can install modified USB sockets into an airport's charging station to transmit malicious code and steal data from your phone. This is known as "juice jacking".
To avoid data theft at the airport, follow these steps:
- Carry your own charger and USB cable. This way, you can use a standard electrical socket to charge your device without risking data theft. Standard electrical outlets are generally safe and also tend to charge your device faster.
- If you must use a USB charging station, use a USB data blocker or a power-only USB cable. These devices prevent data transfer between the charging station and your phone, ensuring that only power is exchanged.
- If you are using a public charging station with a USB port, make sure to select "charge only" if given the option to "share data" or "trust this computer". This will prevent your device from connecting and sharing data with the charging station.
- Opt for wireless chargers if your phone supports wireless charging. Juice jacking does not affect your phone when you charge it wirelessly.
- Invest in a portable power bank. This will allow you to charge your devices on the go without relying on public charging stations.
- Be cautious when using public Wi-Fi networks. Cybercriminals can use these networks to target travelers and gain access to their devices.

Wireless charging at airports
Airports such as Heathrow, Gatwick, JFK, Miami International, Boston Logan International, Dubai International, and Sydney Airport have already implemented Aircharge wireless charging stations. These charging stations can be co-branded by airport partner brands to increase brand awareness and engagement. For instance, airports and their partners can use QR code landing pages and mobile notifications to communicate directly with customers at the point of charge and offer promotional deals and loyalty programs.
While wireless charging at airports is generally considered safe, it is important to be cautious when using any public charging station. "Juice jacking" is a term used to describe a cyberattack where data is stolen from a smartphone or other devices connected to a charging port. This can occur when hackers install modified USB sockets into airport charging stations, allowing them to transmit data from your device to their remote servers. To prevent juice jacking, it is recommended to use a USB data blocker or a power-only USB cable, which blocks data transfer while still allowing your device to charge.
Additionally, it is always a good idea to carry your own charger and USB cable when travelling. This way, you can avoid using unknown chargers or USB slots, reducing the risk of potential data theft or malware attacks. By taking some simple precautions, you can safely charge your devices at wireless charging stations in airports and other public places.

Using your own charger at the airport
To avoid this, it is recommended to carry your own charger and USB cord, and use an electrical outlet instead. Standard electrical outlets are not a threat to transmit data to your phone, and they also tend to charge your device faster. If you are using a USB cable, ensure it is a power-only cable, or use a USB data blocker. If you are using a wireless charging station at the airport, this is also a safer option as your phone is not connected via USB.
If you are using your own charger and cable at the airport, it is still important to be vigilant. Ensure you are using a secure power outlet, and be aware of your surroundings. It is also a good idea to keep your device with you at all times while it is charging.
It is worth noting that some Samsung devices have an Auto Blocker function, which blocks apps from unidentified sources and commands via USB. This can be turned on in your device settings.

Juice jacking and how to avoid it
Juice jacking is a type of cyber attack where hackers use public USB charging ports to gain access to connected devices, such as smartphones or tablets. Attackers can install modified USB sockets into public charging stations, allowing them to transmit malicious code and access data on your device. This data can include personal information, financial details, and even allow them to install malware to monitor your activities.
While the Federal Communications Commission (FCC) has not reported any confirmed cases of juice jacking, the FBI has warned that no public phone charging stations are safe from hackers. This includes stations commonly found in airports, hotels, malls, and other public spaces.
To protect yourself from potential juice jacking, consider the following measures:
- Carry your own charger and USB cable: Avoid using unknown chargers and cables provided at public charging stations. Instead, bring your own charger and plug it into an electrical outlet.
- Use a USB data blocker: Invest in a USB data blocker, also known as a "USB condom," which allows only power to pass through the cable to your device, blocking any potential data transfer.
- Select "Charge Only": When plugging your device into a USB port, always choose the "Charge Only" option if it appears. This prevents any data transfer between your device and the charging station.
- Use wireless charging: If your phone supports wireless charging, opt for wireless chargers at airports or coffee shops. Juice jacking cannot occur through wireless charging.
- Use a power bank: Carry a portable power bank with you when travelling to charge your devices. This eliminates the need to use public charging stations altogether.
- Lock your phone: Ensure your phone is locked with a PIN, fingerprint, or passcode before charging. USB ports typically cannot sync with a locked phone, preventing data access.
By following these simple steps, you can significantly reduce the risk of becoming a victim of juice jacking and protect your personal information while using public charging stations.
