A couple of weeks ago, the FBI issued a warning about public charging ports.
"Avoid using free charging stations in airports, hotels, or shopping centers," it said. "Bad actors have figured out ways to use public USB ports to introduce malware and monitoring software onto devices. Carry your own charger and USB cord and use an electrical outlet instead."
This advice was parroted widely by media outlets – including NPR, The Washington Post, and even this very newsletter from Digital Trends.
But here's the thing: those warnings might be nonsense. In the weeks following the FBI's tweet, some security professionals have called out the agency and argued that these so-called "juice jacking" attacks aren't a legitimate concern.
"There are no documented cases of juice jacking ever taking place in the wild," says ArsTechnica's security editor Dan Goodin. "No one in the past five years has demonstrated a viable juice jacking attack on a device running a modern version of iOS or Android."
So while carrying your own charger isn't a bad idea in any case, it seems that it might not be as crucial as the FBI would have you believe. For now, evidence suggests that public charging ports are probably safe to use.
