FBI cautions against using public phone chargers.

The FBI has warned against using public phone charging stations due to the threat of "juice jacking," where bad actors can load malware onto public USB charging stations to maliciously access electronic devices while they are being charged. Cybersecurity experts warn that malware installed through a corrupted USB port can lock a device or export personal data and passwords directly to the perpetrator. To avoid becoming a victim, the FBI recommends using an AC power outlet instead, bringing your own chargers and cables, and carrying a portable charger or external battery.
