Posting and sharing photos online seems innocuous, but you could be inadvertently leaking sensitive business and personal information, according to experts.
Virtually all smartphones can track you through what is known as geotagging, adding location data from satellites. If you leave your phone's location services on, this information is added to your photos by default. The tag stays with the picture even after it's shared online, allowing you to be tracked.
Chris Hadnagy, CEO of Social-Engineer, a cybersecurity consulting company, showed CNBC how easy the process is. He used a common tool found in most Macs — called Preview — to gain the GPS coordinates from a picture he found online.
"I just take … those coordinates, and you pop them into something like Google Maps," said Hadnagy, who trains law enforcement and businesses on the dangers of location sharing.
Once in Google maps, Hadnagy found the city, neighborhood and exact house the picture was taken in.
