The FBI’s Denver bureau tweeted last week that malicious actors are using public USB ports, such as those found at airports and shopping centers, to disseminate malware and monitoring software. The organization did not offer any particular instances.

The organization said in the tweet to “use an electrical outlet and carry your own charger and USB cord.”

When a device’s battery is extremely low, many people find public charging stations appealing; nonetheless, security professionals have long expressed worries about the risk. To characterize the issue, researchers came up with the term “juice jacking” in 2011.
