FBI warns against 'juice jacking' at public charging stations in airports and hotels.

The FBI has warned against using USB charging stations in public places such as airports, malls, and hotels, as hackers can use them to access personal data and install malware on devices. The agency advises using personal chargers and electrical outlets instead. The warning is part of a regular reminder to keep smartphone users aware of the risks of "juice jacking" and public Wi-Fi networks, which can also be used to target devices and data.
