I love paranoia!! Everything is a disaster just waiting to happen. The internet is great for passing along dis-information and fueling paranoia ... gota love the 'net.
Mr. Pot, please to meet Mr. Kettle.
!. Photo Journalists use their smart-phones, not public WiFi, to do their up-loading. Not a problem for a pro. If your not a pro I'm sure your milage does vary
If you bothered to watch the video, you'd have seen where they showed, for example, a Reuters pool advertisement with most of the cameras with the WiFi module attached. I don't even know how you'd get the pictures from your camera to your smart phone, or why you'd bother.
2. My GoPro Hero3 has a name (to control multiple cameras) and is password protected. WOW, such Hi-Tech in a $400.00 camera.
Again, if you had bothered to watch the video, you'd have seen that, yes, the Canon cameras have a "username" and a "password." And a "session ID" and all sorts of other things that, by their names, you'd nominally think would offer security. Thing is, as one would expect from a company that's not yet been publicly burned by a lapse in security, it's all so much window dressing that doesn't even pretend, behind the scenes, to actually do anything to secure the camera.
I have no clue if the GoPro is any better or worse in this regard. If I had to guess, I'd suggest it's probably about the same.
And this isn't at all paranoia. There is a very long history of all sorts of nasty things happening from lack of security. Hell, it was even a major news story a few years back when poor security caused a vice presidential candidate to lose control over her email account, and there's constant stories of somebody famous's cell phone being hacked and the contact list making the news in the tabloids, all those sorts of things.
The only reason the tabloids aren't using this to steal photos off of each others's cameras is because it's so new that cameras have their own built-in WiFi hotspots that it's only now that it's occurring to people that maybe they haven't been secured.
I wouldn't at all be surprised if there's a story that makes the evening news sometime in the next six months about a camera being hacked using the exact flaws the researchers in the video have discovered. Probably sooner, now that the cat's out of the bag.
One thing I can guarantee you: no way, no how does Pete Souza have WiFi turned on on any of his cameras today.
