'Never charge your phone at the airport' – cybersecurity expert explains why

A cybersecurity expert has warned travelers of the hidden dangers of charging their phones at the airport.

After hours of aimlessly scrolling, checking directions, and connecting with friends and family during a flight, many people find that their phone battery has died. So they head to convenient charging stations with USB ports located in airport terminals.

However, while this is convenient and these terminals may seem like an ideal solution, many travelers have been surprised when hackers have discovered ways to overload them with viruses.

Jay Rowe, of plug adapter manufacturer SIGNAL + POWER, explains the three reasons why you should never charge your phone at an airport.

1. Malware risk

According to Jay, the number one reason you should never charge your phone at the airport is “Convenience comes with great security risks”.

“These ports can be compromised to install malware on your device. This malware can lurk undetected, quietly stealing sensitive information such as passwords and banking details. to explain.

In 2023, the US Intelligence and Security Agency issued a message through its official Twitter account in Denver, which stated: “Avoid using free charging stations at airports, hotels, or malls. Criminals have found ways to use public USB ports to inject malware and trackers into devices.”

2. Juice extraction

The expert then warned of a technique called “juice lifting.” This is the case that Malware can be installed through a damaged USB portOr lock the device or export all your personal data and password directly to the perpetrator.

It works because when it comes to smartphones, the power supply and data flow pass through the same cable. “Once infected, your phone is vulnerable not just at the airport, but anywhere you take it with you.” Jay pointed out.

3. Data report

Finally, charging your mobile device at the airport may result in inadvertent data exposure. Even if the charging station has not been hacked, it could still be at risk.

“Charging stations can transfer data and power. While phones require users to choose between 'charge only' and 'file transfer' modes, this protection is often bypassed by charging stations. As a result, your device may be vulnerable to data eavesdropping or exploitation. This stolen data is later used for identity theft or sold on the dark web. The expert revealed.

Tips to stay safe

In addition to issuing the warning, Jay also shared some tips on how to safely charge your phone at the airport if you find yourself in a situation where you need to.

the The first tip is to invest in a portable charger so you don't have to rely on public charging stations.

Second, stick to trusted sources and only use your own personal charger or borrow it from someone you trust – Wall plugs are also better than USB ports.

“If you must use a public station, turn off data transfer on your phone before connecting. This ensures only current flows through the cable. Also consider 'data blocking' cables.” A data blocking USB prevents data transfer between your device and the charging station, which It only allows the transfer of energy.” Jay explained.
