The TSA is warning flyers to not use airport USB chargers. Doing so, it says, could result in malware infecting your phone or other device. It’s also warning against using airport Wi-Fi.

The agency advised, "So, when you're at an airport, do not plug your phone directly into a USB port. Bring your TSA-compliant power brick or battery pack and plug in there." ...

According to officials, hackers can “install malware” at USB ports in a trend known as “juice/port jacking.” Cybercriminals can then ransom your device or steal your passwords.
