One of the basic technologies that enables what we often refer to as the Internet of Things is embedded Linux, a version of Linux that runs on machines that aren't computers in the traditional sense. A lot of the new "smart" devices joining Wi-Fi networks in the home and office are running some variant of it, as do a lot of those home-Wi-Fi routers themselves. Researchers at security-software company Symantec say they've found a worm that proves that, eventually, these devices may be ripe for attack. It's called Linux.Darlloz, and it appears to have been built to infect versions of Linux found in home routers, TV set-top boxes and security cameras, and also some industrial-control systems.

The Internet of Things--a state in the not distant future when hundreds of billions of objects now disconnected from computer networks will routinely transmit data across the web--will require a new privacy paradigm, says the Future of Privacy Forum.
