KrebsOnSecurity received a nice bump in traffic this week thanks to tweets from the Federal Bureau of Investigation (FBI) and the Federal Communications Commission (FCC) about “juice jacking,” a term first coined here in 2011 to describe a potential threat of data theft when one plugs their mobile device into a public charging kiosk. It remains unclear what may have prompted the alerts, but the good news is that there are some fairly basic things you can do to avoid having to worry about juice jacking.

You’re out and about, and your smartphone’s battery is about to die. Maybe you’re at an airport, hotel, or shopping mall. You don’t have the power cable needed to charge the device, but you do have a USB cord that can supply the needed juice. Then you spot an oasis: A free charging kiosk.

This past week, I was reminded of a conversation I had with an ethical hacker I met at the annual Defcon security conference in Las Vegas, who showed me what may have been (and still remains) the shortest and most elegant trick I’ve seen to crash Internet Explorer 6 Web browser. I was reminded because the guy who told me about it said it still worked, even though he alerted Microsoft to the flaw back in 2004.
