Personal webcams

In 2014 a voyeuristic website popped up in the news.It streamed video from thousands of webcams located in 250 world countries.You might well have been responsible for one of the biggest-ever attacks on the internet last week. 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.

But even if every device that was used in the attack was recalled, the threat will still exist – technologists have repeatedly warned about insecure and unsafe internet of things devices, and people are likely to continue making them.

As it turned out, users all across the globe made the same simple mistake, which let the hackers in.

The users kept the device’s default passwords or chose weak combinations like 12345.

The server this time was a domain name system server, which helps direct browsers to the right websites, run by a company called Dyn.

But next time it could be anything else – and the size of the attack might mean that it needs only be an attack on something relatively dull to cause huge damage across the world.
