Public USB port in airports, hotel lobby or transit stations may be easy to keep your phone easy, but they can provide hackers to your information! Here you should know what to keep your information safe.
Juice Jacking: What is it and how does it work?
This danger, known as “juice jacking”, allows hackers to steal malware or data by modifying USB hardware behind charging stations. Once plugged in, your phone can quietly authorize a data connection, allowing attackers to reach personal information, photos, credentials or even remote controls.
Researchers of events such as DEF Con Hacking Conference have displayed how easily the manipulated kiosks can remove data using hidden hardware elements. In 2025, academics also revealed a new version called “choice of choice”. In this case, the malicious microcontroller indicates the permission to bypass.
How common is this? Large -scale attacks have not been confirmed, but TSA, FBI, FCC and other agencies issue advice due to the severity of potential threats. Security experts describe it as “low-affection but high-effects” risk.
Here's how you can protect yourself
- Use an individual AC charger or portable power bank.
- Use only cable or USB data blockers to block data lines.
- If a public device asks, the data always rejects access signals.
- Avoid unknown or suspected charging stations, especially in high -risk environments such as airports or public transit hubs.
- Keep OS and firmware updated; The iOS 18.4 and Android 15 include strong security – although some equipment may still weaken.
- If you plug your device to the USB port and see messages like “share data” or “relying on this computer” or “only charge”, always choose “only charge”.
It is best to consider using portable hotspots with a built-in battery to completely release public charging stations. No cable, no compromise, no risk.
Tools supporting many connected users can also be great for families, friends or group trips when the strength of a battery or signal becomes a problem.
