Do you use a webcam to check on Tiddles the cat or Bonzo the dog while you're at work?
If so, you could be unwittingly turning your internet-connected "smart" home into a weapon of web destruction.
That's the unsettling conclusion to be drawn from the recent web attacks that made use of a botnet army of compromised connected devices, from webcams to printers, to knock out a number of popular websites.
The smart home, it seems, is pretty dumb when it comes to security.
Wi-fi routers, digital video recorders, controllable lighting, security cameras - all these devices offer a potentially easy way in to your network and then the wider internet.
As the Internet Society warned last year: "The interconnected nature of IoT [internet of things] devices means that every poorly secured device that is connected online potentially affects the security and resilience of the internet globally."
