Say you’re going to Sochi for the Winter Olympics. You’ve magically found a hotel that’s actually complete and not full of trash and construction equipment. Crisis averted, right? Not quite—because as NBC Nightly News’ experiment shows, your computer or smartphone could be hacked in seconds in Sochi. Hackers will be going after your computer or smartphone from the minute you land. Yes, as NBC’s Richard Engel shows in this Nightly News segment, devices he brought to Sochi were hacked within mere moments of connecting to a public Wi-Fi network. They were decoys, of course, loaded with bogus information. But it wasn’t just a one-time fluke—every device Engel brought was seemingly hacked. Now, to be fair, public Wi-Fi networks are notoriously dangerous; that’s true in every village around the world, Olympic or otherwise.
