Juice Jacking
Related to my last post: there is a cyber attack called “Juice Jacking”: someone installs a malicious USB port at a place where you’d plug in to charge your device, and that port installs hacking software on your device.
You can guard against this by using a “USB Condom”: a special (and cheap) USB adapter that only has the power cords connected. No software can physically cross the wire, so no hacking is possible.
