Internet outage was caused by personal webcams, meaning people provided firepower for shutdown without knowing it

You might well have been responsible for one of the biggest-ever attacks on the internet last week. And you're probably going to do it again. A huge network of webcams and other internet of things devices is being built that can be used as perhaps the biggest cyberweapon ever created. And those people who own the devices probably don't even know that they're infected with the malicious code that allows them to be used that way. To be involved in the attack, you wouldn't need to do more than buy a common webcam – perhaps for keeping an eye on your house, or a pet that lives in it – or any other connected home or internet of things device.
