Public USB ports in airports, hotel lobbies or transit stations, might make it easier to keep your phone charged, but they could be giving hackers access to your info! Here’s what you need to know to keep your info safe.

Juice Jacking: What Is It and How Does It work?

This threat, known as “juice jacking,” allows hackers to install malware or steal data by modifying the USB hardware behind charging stations. Once plugged in, your phone might silently authorize a data connection, giving attackers access to personal info, photos, credentials or even remote control.

Researchers at events like Def Con Hacking Conference have demonstrated how easily manipulated kiosks can extract data using hidden hardware elements. In 2025, academics even revealed a new variant called “ChoiceJacking.” In this case, malicious microcontrollers bypass permission prompts.

How common is it? There have been no confirmed large-scale attacks reported but the TSA, FBI, FCC, and other agencies continue to issue advisories due to the severity of the potential threat. Security experts describe it as a “low-probability but high-impact” risk.

Here’s How You Can Protect Yourself

• Use a personal AC charger or portable power bank.
• Use charge-only cables or USB data blockers to block data lines.
• Always decline data access prompts if a public device asks.
• Avoid unknown or suspicious charging stations, especially in high-risk environments like airports or public transit hubs.
• Keep OS and firmware updated; iOS 18.4 and Android 15 include stronger protections—though some devices might still be vulnerable.
• If you plug your device into a USB port and see a message like “share data” or “trust this computer” or “charge only,” always choose “charge only.”

It’s best to consider using a portable hotspot with a built-in battery to skip public charging stations altogether. No cables, no compromises, no risk.

Devices that support multiple connected users can also be great for families, friends or group trips when battery or signal strength becomes an issue.
