FBI warns against 'juice jacking' at public charging stations.

The FBI is warning people not to use USB charging stations at airports, hotels, and shopping centers due to "juice jacking," a process where hackers manipulate the USB ports to put malware on people's phones and copy their data. Cybersecurity experts recommend using your own charging block or purchasing a special cord made only for power to protect yourself. The FBI also recommends plugging into a power outlet. If you've already plugged your phone into a USB port in public, you're probably okay, but it's best to stay cautious to keep your data safe.
