A few years ago I wrote about the danger of “juice jacking” highlighting the security risks posed by USB charging in public places, where a bad actor could attempt to hack your phone or laptop to steal your precious data or install malware/ransomware.
In most cases, there are no risks at home, but it’s when you charge your device in a public place notably an airport or train station that you could be at risk of hacking. If you’re using an Android phone, there’s an easy way to detect Juice Jacking, and whether something fishy is going on as shown in the screenshots below.
On the left screenshot, I connect my phone to a USB charger, all that changed was the battery icon changed to show it’s charging. But on the right screenshot, I connected my smartphone to my laptop, and since it’s trying to access data, I’m offered three options: transfer photos, transfer files, or charge only.
I suppose you can see where it’s going, as if you can see the right screenshot while charing in a public place that’s only supposed to charge your phone, you’ll know something is not right. I’m using Huawei Prime Y9 2019 running Android 10, but this should be similar with other Android phones. More generally, if you connect a device to a charging pod, and it’s asking you whether it’s OK to transfer photos or files, or access any type of data, something is not quite right. So to avoid juice jacking, you may want to make sure it’s only using the device for charging and inform the person in charge of the location.
