Is anyone truly secure in their home? That may not be the case in a world where bridges are being connected by rapidly improving technology. And with off-the-shelf smart devices becoming increasingly common features in homes, it seems that it's easier than ever to invade the sanctity of a personal space.

This was demonstrated by researchers from the American Associates Ben-Gurion University of the Negev (AABGU). Their main body of work focuses on identifying the vulnerabilities of networks and devices in the home. As part of that continuing effort, the team took apart and reverse engineered a slew of gadgets commonly seen in most homes. Through this, they were able to discover that a number of security issues plagued baby monitors, doorbells, thermostats, and home security cameras.

The biggest of these issues lay in the passwords. For one, common default passwords are shared by the same products even if they're sold under different brand names. Very rarely do business owners and consumers come up with new device passwords after buying these products, so there's a good chance they've been using an unsafe password for as long as they've been using a certain device. Moreover, retrieving the password stored in a device allowed the researchers to access entire wi-fi networks.
