The Transportation Security Administration (TSA) has once again sent a clear message to travelers using airports in the United States. The agency urged not to use the public USB ports available in the terminals, an option that is often tempting for those who need to charge their phone before boarding but which has also become a direct path for cyberattacks. The aim of the warning is to stop a modality that can put personal data at risk and expose passengers to the risk of fraud.
The TSA had already spread a similar message across its networks at the beginning of 2025. He pointed out that the criminals They can install malware on public charging ports to access the devices that connect. An action as simple as connecting a cable can open the door to data extraction or installation of programs that can break a phone. Therefore the general recommendation remains: Avoid USB charging stations and opt for your own chargers or external batteries.
The Federal Communications Commission (FCC) also issued a corresponding notice in 2023. She recommended carrying personal cables and car chargers when traveling. One of their main proposals involves the use of charging-only cables that can prevent data exchange while the device is connected to power. The company emphasized that this type of accessories, purchased from reliable suppliers, significantly reduces the risks associated with public charging stations.
Cybersecurity specialists identify another critical point at airports: open Wi-Fi networks. Eric Plam, Managing Director of SIMO, explained: USA today that any password exchange on public networks can be vulnerable. The risk increases when the passenger browses websites where he enters sensitive data or makes online purchases.
Plam suggested using password managers to encrypt keys and limit the reach of scammers. He also recommended using VPN, which provides an additional layer of security between the device and the servers the user accesses.
The warnings cover specific devices. Instructions given by Forbes They pointed out that iPhone users should adjust the “Wired Accessories” setting, which defaults to “Auto-allow when unlocking.” The recommendation is to change the option “Always ask” or “Ask for new accessories”. This setting forces the user to authorize each connection and gives greater control over access to the device.
The FCC explained that cybercriminals are exploiting a modality called juice jacking, which involves installing malware on USB charging stations to obtain personal information. This allows malware to lock the device or extract passwords directly. Given this danger, experts recommend using USB data blockers. These small devices allow you to charge your phone without transferring information. This is a simple measure that provides an additional barrier against digital theft attempts.
Authorities emphasized that prevention remains the best option. Own accessories, secure networks and appropriate configurations can avoid setbacks for travelers at the airport.
