Comment on Wi-Fi security and fake ac/dc charges threaten your data at the 2014 World Cup by Henry
Thanks for your article. One suggestion I’d add is the recommendation for cell phone users to always carry at least one USB cable which is for charging only, that is, it only contains two wires connected to only two pins on each USB connector at the ends, so only DC can go through. If such cables aren’t ready-made, we have to customize a fully-populated (all pins wired) cable so that only the minimum two go through. (And have an extra as backup in case one fails.) That should foil potential snoops trying to enter via USB.
