Details matter. As this article from Defense Tech shows, not understanding the hidden side of technology can have deadly consequences:
When you take a photo with your cellphone, the gps coordinates of the location you took the picture is embedded into the image. When you upload said photo onto the internet for all to see, people can pull the location data from that picture. If you think this is just people being paranoid and that the Taliban would never do this in Afghanistan, think again. Insurgents figured out how to use this to their advantage in Iraq years ago. In 2007, a group of Iraqi insurgents used geotags to destroy several American AH-64 Apache choppers sitting on a flightline in Iraq.
Once again, it’s worth remembering that by far the biggest vulnerability in any secure system is the people involved. In this case, the troopers involved weren’t stupid or reckless – they just needed a little more training on the way their information can be used.
