If your business or home has a live video camera you might be surprised who can view it. Just imagine your conference room has the ability to have live video conferences with clients, if it is not secure others may be able to watch and listen in on all of your meetings. Additionally if the feed is always live as in security cameras in businesses, stores, restaurants, traffic cameras, etc. a person can view this live feed anytime. If a security feed is not secure and someone gains access to confidential company information, just imagine the chaos that may ensue if that information is exposed or sold to a competitor.
There is a search engine called Shodan that allows searches for all devices connected to the Internet. This includes live web cams, refrigerators, routers, GPS receivers, even swimming pool, industrial and medical device control panels. How does Shodan receive this information? Simple it asks these devices "What can you tell me about yourself?" Most of the information discovered is from people who are not even aware that this information is viewable to others. A man was viewing open web cam feeds and discovered a woman yelling and hitting an elderly woman. Shocked by his discovery he recorded it, traced the IP address and submitted it to the police.
John Matherly is the creator of Shodan and is currently the only one maintaining it. Typically the work he does is only done by criminals. He supports this project by charging security companies for access to his entire database, which currently has more than 1.2 billion devices. Currently anyone can search his database for free, but unlimited access will cost you a one time fee of $19. With this information make sure that all of your Internet connected devices are secure.
